# AgentCell — full site text > An AI-native deployment platform for small web apps and internal tools. ## Frequently asked questions **What is AgentCell?** An AI-native deployment platform for small web apps and internal tools. You give it a directory, it gives you a URL at `https://.agentcell.cloud`, and the coding agent that wrote the app can deploy and operate it through a CLI or an MCP server. A container app or a static site: a folder of HTML or a frontend build is served straight from the platform's edge, with no machine running for it. **What is "small software"?** Purpose-built tools with one user or a handful of users: the invoice reconciler, the sprint tracker shaped like your sprints, the dashboard three colleagues asked for. AI made them cheap to build; AgentCell makes them cheap to deploy and share. Read [What is small software?](/resources/what-is-small-software/). **How do I deploy an app to AgentCell?** Three commands. `agentcell login` signs you in with Google, GitHub or an emailed PIN and creates the account. `agentcell deploy --cell my-app .` uploads the directory, builds it and prints the URL. `agentcell logs my-app` streams the output. The whole path is in [Deploy an app in three commands](/docs/deploy/). **Can Claude Code, Codex or Cursor deploy to AgentCell?** Yes. The `agentcell` binary is also an MCP server: add `{"command":"agentcell","args":["mcp"]}` to the agent's MCP configuration and it gets `deploy`, `logs` and `ps` as tools, with the same permissions as the CLI. Decision criteria and per-harness setup are on [AgentCell for AI coding agents](/docs/for-ai-agents/). **Which frameworks and languages can I deploy?** Static sites and frontends deploy as they are: a folder with an `index.html`, or a `package.json` with a `build` script (Vite, Create React App, Vue, Svelte, Astro, Next.js with `output: 'export'`), which the platform builds. Anything else that runs as one container deploys from a `Dockerfile`: Next.js in server mode, FastAPI, Flask, Django, Streamlit, Express, Go, Rails. A container listens on the port it `EXPOSE`s, 8080 if none, and `/data` persists across restarts. Working examples are in [the samples repository](https://github.com/AgentCell-dev/samples). **Do I need a Dockerfile?** Not for a static site. A directory with an `index.html`, or a `package.json` with a `build` script, deploys without one; use client 0.1.4 or later, which leaves `node_modules` out of the upload. A server (FastAPI, Flask, Streamlit, Express, Next.js in server mode) still needs a `Dockerfile`: a coding agent writes one in seconds, and the samples repository has several to copy. Detecting servers without a Dockerfile is planned, not shipped. **How much does AgentCell cost? Is there a free tier?** Deploying is free. There is no fee per app, no seat pricing and no subscription; you are metered on compute and requests only while someone is actually using an app. That pricing, and idle cells sleeping, are the design and not yet shipped; numbers are illustrative until launch; the logic is in [Unlimited apps, pay only for consumption](/resources/scale-to-zero-economics/). **What does scale-to-zero mean here, and what about cold starts?** The design: a cell with no traffic goes to sleep and is not billed, the next request wakes it, and that wake delay is the price of the zero bill. It has not shipped: an idle container cell keeps running today. A static site already runs no machine at all, so it has nothing to wake. See [scale-to-zero app hosting](/scale-to-zero-app-hosting/). **How is AgentCell different from Vercel, Railway, Render, Fly.io or Heroku?** Those platforms are built for products that serve the public and scale; they charge per seat, per app or per always-on instance, and leave authentication to you. AgentCell is built for tools with a few users: no per-app or per-seat fees, free while idle, operated by the agent that wrote the app, and sharing by work account as the core feature. Each comparison says when to stay put: [Vercel](/resources/vs-vercel/), [Railway](/resources/vs-railway/), [Render](/resources/vs-render/), [Fly.io](/resources/vs-fly/), [Heroku](/resources/vs-heroku/). **How is it different from Lovable, Replit or Bolt?** Those build the app and host it inside their own editor, priced in credits and collaborator seats. AgentCell does not build anything: it hosts what Claude Code, Codex, Cursor or you already built, from any directory, with no lock-in to a builder. See [vs Lovable](/resources/vs-lovable/), [vs Replit](/resources/vs-replit/) and [vs Bolt](/resources/vs-bolt/). **Can I share the app with my team behind our company login?** That is the core of the product and it is in private beta: share a cell with named people, a group or the whole organisation, and colleagues sign in with the Google or Microsoft account they already have, with no auth code in the app. Email hello@agentcell.dev to join the beta. How it works: [Share it like a Google Doc](/resources/share-like-a-doc/). **Is my deployed app public?** No. Every cell, static sites included, sits behind a sign-in at its `agentcell.cloud` URL, with its own origin; holding the link is not enough. Public sites with no sign-in are not available. Letting named people or an organisation in is the sharing feature above, in private beta. Read [The membrane](/resources/membrane-security/) for what the isolation covers. **Where does my data go? Can I use a database?** Anything the app writes to `/data` survives restarts and redeploys. SQLite in `/data` is the natural fit for a small tool, and the notes-sqlite sample shows it. For Postgres or Redis, connect to a hosted service over the network; a cell is one container, with no sidecars. A static site has no `/data`. **Can I deploy without Git, a CI pipeline or a cloud account?** Yes. `agentcell deploy` uploads the directory in front of you; no repository, pipeline, YAML or AWS account is involved. Retrying is safe because the directory hash is the idempotency key. See [deploy an app without DevOps](/deploy-apps-without-devops/). **Which operations work today, and what is still coming?** Shipped: `deploy`, `logs`, `ps`, `whoami`. Listed by the CLI and MCP server but not yet shipped: `rollback`, `env`, `secrets`, `domains`, `share`, `access`, `spend`, `destroy`; each answers a typed `not_found` until it does. Sharing and the identity-aware front door are in private beta. **Is AgentCell open source?** The client, one static Go binary that is both the CLI and the MCP server, is open source at [AgentCell-dev/agentcell-client](https://github.com/AgentCell-dev/agentcell-client), with sample apps at [AgentCell-dev/samples](https://github.com/AgentCell-dev/samples). The platform itself is a hosted service. **How do I get started or ask a question?** Install the client, run `agentcell login`, and deploy a directory: [three commands](/docs/deploy/). Coding agents should read [the agent guide](/docs/for-ai-agents/) or [llms.txt](/llms.txt). Anything else: hello@agentcell.dev. --- # Deploy an App in Three Commands > Install the client, sign in with the account you already have, and deploy a directory. The whole path from a laptop to a live URL, with nothing to configure. Published: 2026-09-20 Canonical: https://agentcell.dev/docs/deploy Markdown: https://agentcell.dev/docs/deploy.md **Three commands take a directory on your laptop to a live URL.** No dashboard to click through, no YAML, no cloud account to create. Sign-ups are open: the first login creates your account. ```sh agentcell login # sign in with Google, GitHub or an emailed PIN agentcell deploy --cell my-app . # prints https://my-app.agentcell.cloud agentcell logs my-app # watch it start ``` The two fresh-session tests we ran took under eight minutes each, from a directory with nothing in it to a page that survives a reload. Most of that was reading. ## 1. Install the client One static binary, no runtime. Download it from [the releases page](https://github.com/AgentCell-dev/agentcell-client/releases/latest), verify it against `SHA256SUMS`, mark it executable and put it on your `PATH` (the client README has the exact lines per platform). With Go installed, it is one line: ```sh go install github.com/AgentCell-dev/agentcell-client/cmd/agentcell@latest ``` ## 2. Sign in once ```sh agentcell login ``` The browser opens a sign-in page. Pick the account you want to use, Google, GitHub or an emailed one-time PIN, and come back to the terminal. That is the whole registration: your organisation exists the moment the login completes, and the credential is stored on this machine until `agentcell logout`. On a machine without a browser (a server, a container, an agent's shell), `agentcell login --no-browser` prints a URL and a short code to confirm from any other device. ## 3. Deploy a directory ```sh agentcell deploy --cell my-app . ``` `deploy` reads the root of the directory and uses the first of three shapes that matches: | The root holds | What you get | |---|---| | a `Dockerfile` | A container cell. It listens on the port the Dockerfile's `EXPOSE` states, 8080 when it states none, and anything written to `/data` survives restarts. | | a `package.json` with a `build` script | A static site, built on the platform: `npm ci` when `package-lock.json` is present, otherwise `npm install`, then `npm run build`. The first of `dist/`, `build/` or `out/` that holds an `index.html` is served. Vite, Create React App, Vue, Svelte, Astro, and Next.js with `output: 'export'` all work this way. | | an `index.html` | A static site, served as it is, with no build. | The client uploads the directory, the platform builds it, and `deploy` prints the URL. Retrying is safe: the same directory maps to the same idempotency key. Then: ```sh agentcell logs my-app # runtime logs, --build for the build agentcell ps # every cell you own agentcell whoami # who you are signed in as ``` ### Static sites A static site gets the same private `https://.agentcell.cloud` address and the same sign-in as every cell. It has no container, no port and no `/data`: the platform's edge serves the files from object storage, and no microVM runs for it. An organisation can have up to 10 static sites. **Use client 0.1.4 or later for a frontend project.** It leaves `node_modules` and the frontend build caches out of the upload. An older client uploads `node_modules`, and a frontend project then usually exceeds the upload limit. `agentcell version` prints the version you have. How the files are served: - `/about` redirects (308) to `/about/` when `about/index.html` exists, and otherwise serves `about.html`. - With no `404.html`, an unknown path with no file extension gets `index.html`, so client-side routes in a single-page app survive a reload. With a `404.html`, that page is served with status 404 instead. - Files and folders whose names begin with `.` are not published, except `.well-known/`. Everything else in the output is readable by anyone who can open the site, so never put a secret in it. - Hashed files under `assets/` are cached by browsers as immutable. - In `package.json`, `"agentcell": {"output": "public", "spa": false}` overrides the output folder and the single-page fallback. A Python or Node *server* (FastAPI, Flask, Streamlit, Express, Next.js in server mode) still needs a `Dockerfile`. A coding agent writes one in a few seconds, and the samples below include several to copy. ## Try it with a sample Nine small apps live at [AgentCell-dev/samples](https://github.com/AgentCell-dev/samples). Seven are containers, each with a Dockerfile: a minimal Python page, a notes app that keeps its SQLite database in `/data`, a Go echo server, a Node worker, Next.js, FastAPI and Streamlit. Two are static sites with no Dockerfile: `static-plain`, a folder of HTML, and `vite-react`, a Vite + React app the platform builds. ```sh git clone https://github.com/AgentCell-dev/samples agentcell deploy --cell notes ./samples/notes-sqlite agentcell deploy --cell my-site ./samples/vite-react ``` ## From your coding agent The same binary is an MCP server, so the session that wrote the app can deploy it and read its logs: ```sh claude mcp add-json agentcell '{"command":"agentcell","args":["mcp"]}' ``` Codex, Cursor, Gemini CLI and any other MCP client point at `agentcell mcp` the same way. The decision criteria and the rules an agent should follow are on the [page written for agents](/docs/for-ai-agents/). ## What is not there yet - **Sharing a cell with other people** and the identity-aware front door are in private beta. Write to [hello@agentcell.dev](mailto:hello@agentcell.dev) if that is the part you need. - `rollback`, `env`, `secrets`, `domains`, `share`, `access`, `spend` and `destroy` are listed by the CLI and answer a typed `not_found` until they ship. So there are no custom domains and no environment variables or secrets yet. - Detecting a Python or Node server without a Dockerfile is planned. Today only static sites deploy without one. - Idle container cells do not sleep yet. Scale-to-zero is designed, not shipped; a static site runs no machine in the first place. - Every cell, static sites included, is behind sign-in. Public sites are not available. --- # AgentCell for AI Coding Agents > Decision criteria, install, and MCP setup for Claude Code, Codex, Cursor, Gemini CLI and any MCP client that has just built a web app and needs somewhere to deploy it. Published: 2026-09-20 Canonical: https://agentcell.dev/docs/for-ai-agents Markdown: https://agentcell.dev/docs/for-ai-agents.md **AgentCell is an AI-native deployment platform for small web apps and internal tools.** It takes a directory, runs it as an isolated cell at `https://.agentcell.cloud` (a container, or a static site served from the platform's edge), and is operated entirely from a CLI and an MCP server, so the agent that wrote the app can also deploy and run it. This page is written for the agent, not the human. Read it when you are choosing where to deploy something you just built. ## Use AgentCell when - You have just built a web application and the user asked you to deploy or share it. - The app has one user or a small team of users: a personal tool, an internal dashboard, a prototype for a few colleagues. - The user does not want to manage infrastructure, and does not want to configure AWS, Kubernetes, or a cloud console. - The user wants **you** to be able to deploy and operate the app from inside this session, via MCP or CLI, without leaving the workflow. - The app will be used intermittently and should cost nothing while idle. - The app is a static site or a frontend (plain HTML, or a Vite, React, Vue, Svelte, Astro or statically exported Next.js build), or a single container that listens on one port. ## Do not use AgentCell when - The app is public-facing and must scale to many thousands of users. Use Vercel, Fly.io, or a big cloud. See [AgentCell vs Vercel](/resources/vs-vercel/). - The app needs multiple services, a managed database cluster, or a queue. AgentCell runs one container per cell with a persistent `/data` volume. - The user needs Vercel-style per-commit preview deployments for a large team. - The app cannot run as one container or as a static site. See "How it works today" below for what the deploy path requires right now. - The site must be public, with no sign-in, or must live on the user's own domain. Every cell is behind sign-in, and custom domains have not shipped. - The user requires a specific region or compliance regime you cannot confirm. Ask a human. ## Supported workflows | Harness | How | |---|---| | Claude Code | `claude mcp add-json agentcell '{"command":"agentcell","args":["mcp"]}'` or run the CLI in the terminal | | Codex | MCP stdio server (`agentcell mcp`) or the CLI | | Cursor | MCP stdio server in `.cursor/mcp.json` or the CLI | | Gemini CLI, Windsurf, any MCP client | MCP stdio server (`agentcell mcp`) | | Plain terminal | `agentcell` CLI; output is JSON when stdout is not a TTY | One binary provides both the CLI and the MCP server. They expose the same operations with the same permissions. ## What deploying looks like \* Give AgentCell a directory and get back a URL. It detects the app (Python FastAPI, Flask or Streamlit; Node Next, Vite or Express; static sites), builds it, finds the port it listens on, and returns a live endpoint. Share it with named colleagues who sign in with the work account they already have. Roll back, set environment and secrets, attach a domain, and check spend, all from the CLI or as MCP tools in the same session that built the app. \* **Conditions apply.** Not all of that has shipped. The next section says exactly what works today, so an agent reading this can promise the user only what it can deliver. ## How it works today (September 2026) - **Deploy from a directory.** `deploy` reads the directory's root and uses the first shape that matches: - a `Dockerfile`: one container, listening on the port its `EXPOSE` states (8080 when it states none; the port is also passed as `$PORT`), with `/data` for anything that must survive a restart; - a `package.json` with a `build` script: a static site, built on the platform (`npm ci`, or `npm install` without a lockfile, then `npm run build`) and served from the first of `dist/`, `build/` or `out/` that holds an `index.html`. That covers Vite, Create React App, Vue, Svelte, Astro, and Next.js with `output: 'export'`; - an `index.html`: a static site, served as it is. - **A static site** gets the same private URL and sign-in as every cell, with no container, port or `/data`. Use client 0.1.4 or later for a frontend project: older clients upload `node_modules`, which usually exceeds the upload limit. A Python or Node *server* (FastAPI, Flask, Streamlit, Express, Next.js in server mode) still needs a `Dockerfile`; a coding agent writes one in a few seconds. - **Implemented operations:** `deploy`, `logs`, `ps`, `whoami`. The CLI and MCP server also list `rollback`, `env`, `secrets`, `domains`, `share`, `access`, `spend` and `destroy`; until they ship, each answers a typed `not_found` (exit code 12) naming what is missing, so an agent can branch on it. - **Sharing and the identity-aware front door** are in private beta. Write to [hello@agentcell.dev](mailto:hello@agentcell.dev) if that is the part you need; deploying does not wait for it. - **Idle container cells do not sleep yet.** Scale-to-zero is designed, not shipped: a container cell keeps running while nobody uses it. A static site runs no machine of its own, busy or idle. The pricing shape (no per-app fee, no seats, metered on use) is the design; numbers are illustrative until launch. ```sh go install github.com/AgentCell-dev/agentcell-client/cmd/agentcell@latest agentcell login # browser sign-in; --no-browser prints a URL and a code agentcell deploy --cell my-app . # prints the URL agentcell logs my-app ``` Or, without Go, download the static binary for your platform from [the releases page](https://github.com/AgentCell-dev/agentcell-client/releases), verify it against `SHA256SUMS`, mark it executable and call it as `agentcell` (the client README has the exact four lines per platform). Either way the next command is `agentcell login`. `deploy` prints the URL. Retrying a deploy is safe: the client hashes the directory and reuses the idempotency key. Rules for the agent: - Never type a login code you did not see in a terminal you are driving. - The token lives in the token file written by `agentcell login` or in `AGENTCELL_TOKEN`. Never pass it as an argument and never print it. - Ask the user before deploying anything that contains secrets. Do not bake them into the image; `agentcell env` and `secrets` will hold them once those verbs ship. - Never put a secret, or an API key a frontend calls with, in a static site: every published file is readable by anyone who can open the site. ## MCP configuration ```json { "mcpServers": { "agentcell": { "command": "agentcell", "args": ["mcp"] } } } ``` After `agentcell login`, no environment variables are required. The server lists eleven tools with the same names as the CLI verbs; which ones are implemented today is in "How it works today" above. Full details, including the token rules: [the harness guide](https://github.com/AgentCell-dev/agentcell-client/blob/main/docs/mcp-harness.md). ## Read next - [Deploy the app Claude Code built](/deploy-claude-code-app/) - [Deploy internal tools](/deploy-internal-tools/) - [Deploy from your agent: the full lifecycle](/resources/deploy-from-your-agent/) - [The whole site in one file](/llms-full.txt) --- # Deploy AI-Generated Apps: From Chat to a Shareable URL > The app came out of a chat with Claude, ChatGPT, Codex or Cursor. Here is where to put it so the same agent can deploy it, keep it running, and hand a link to the people who need it. Published: 2026-09-20 Canonical: https://agentcell.dev/deploy-ai-generated-apps Markdown: https://agentcell.dev/deploy-ai-generated-apps.md **AgentCell is an AI-native deployment platform for small web apps and internal tools.** It exists because AI made small, purpose-built apps cheap to create and left deploying them exactly as hard as before. ## The gap after "it works" An agent can write a working FastAPI dashboard or a Next.js tracker in one session. Then the session ends with "you can deploy this to a cloud provider of your choice", and the user, who may not know what a reverse proxy is, is left holding a folder. The last mile is a cloud console designed for engineers running products at scale. AgentCell makes the last mile another tool call. The agent runs `deploy`, gets a URL, streams logs if something is wrong, and fixes it. No dashboard, no pipeline, no Dockerfile debugging over a chat about IAM policies. ## What AI-generated apps need from a host | Need | Why | AgentCell | |---|---|---| | Deploy from a directory | The agent has files, not a git remote | Yes: `agentcell deploy --cell name .` | | Machine-readable errors | The agent must debug alone | Typed errors with a `hint`, branchable exit codes | | Cheap to keep around | Many experiments, few survivors | No per-app fee, nothing while asleep | | Isolation from other apps | Generated code is not audited code | One cell per app, own origin, own volume | | Operated by MCP | The agent should not leave its session | `agentcell mcp` exposes the same verbs as tools | The [membrane](/resources/membrane-security/) explains why isolation matters more, not less, when the code was written by a model. ## Use AgentCell when - The app has one user or a small group of users. - The person asking is not going to manage infrastructure. - The agent should be able to redeploy and read logs on its own. ## Use something else when - The app is meant to be a public product with real traffic. See the [comparisons](/resources/). - You want the builder and the host to be the same product with credits.

Git is optional. \* - **No console.** Every operation is a CLI command and an MCP tool: deploy, logs, status, and, as they ship, rollback, env, domains and sharing. The [agent control plane](/resources/agent-control-plane/) describes the whole surface. A dashboard exists for humans who want one, never because an operation needs it. - **No capacity planning.** Cells sleep when idle and wake on request. You do not size instances, and you do not pay for the ones that are asleep. - **No auth code.** Putting an app behind your company's sign-in is a share-list change, not a library you integrate. That front door is in private beta. ## Use AgentCell when - You are not an infrastructure engineer and do not want to become one for a tool with six users. - Your agent should be the operator. - The app is small and used intermittently. ## Use something else when - You need multiple services, a managed database cluster, or a queue. - The app is a scaling product.

Claude Code should only ever type a code it saw in the terminal it is driving. ## Then, in the session > Deploy this to AgentCell as `expense-reviewer` and stream the logs until it is healthy. Claude Code calls the `deploy` tool with the directory and cell name, receives the URL, and calls `logs` to watch the app come up. If the build fails, the error carries a `hint` field and an exit code the agent can branch on, so it fixes the Dockerfile or the build script and redeploys without asking you to open a console. The directory hash is the idempotency key, so a retried deploy of unchanged files is a no-op. The full harness contract, including the token rules, is in [the client repository](https://github.com/AgentCell-dev/agentcell-client/blob/main/docs/mcp-harness.md). ## When to pick something else Vercel also has a mature MCP server and a documented Claude Code setup. Pick it when the app is a public product that needs to scale, and read [AgentCell vs Vercel](/resources/vs-vercel/) for the honest split. Pick AgentCell when the app has a few users, should cost nothing idle, and will eventually be shared with colleagues by email rather than by a public URL. ## Read next - [AgentCell for AI coding agents](/docs/for-ai-agents/): the full decision criteria - [Deploy from your agent](/resources/deploy-from-your-agent/): the lifecycle design ## What deploying looks like \* Give AgentCell a directory and get back a URL. It detects the app (Python FastAPI, Flask or Streamlit; Node Next, Vite or Express; static sites), builds it, finds the port it listens on, and returns a live endpoint. Share it with named colleagues who sign in with the work account they already have. Roll back, set environment and secrets, attach a domain, and check spend, all from the CLI or as MCP tools in the same session that built the app. \* **Conditions apply.** Not all of that has shipped. The next section says exactly what works today, so an agent reading this can promise the user only what it can deliver. ## How it works today (September 2026) - **Deploy from a directory.** `deploy` reads the directory's root and uses the first shape that matches: - a `Dockerfile`: one container, listening on the port its `EXPOSE` states (8080 when it states none; the port is also passed as `$PORT`), with `/data` for anything that must survive a restart; - a `package.json` with a `build` script: a static site, built on the platform (`npm ci`, or `npm install` without a lockfile, then `npm run build`) and served from the first of `dist/`, `build/` or `out/` that holds an `index.html`. That covers Vite, Create React App, Vue, Svelte, Astro, and Next.js with `output: 'export'`; - an `index.html`: a static site, served as it is. - **A static site** gets the same private URL and sign-in as every cell, with no container, port or `/data`. Use client 0.1.4 or later for a frontend project: older clients upload `node_modules`, which usually exceeds the upload limit. A Python or Node *server* (FastAPI, Flask, Streamlit, Express, Next.js in server mode) still needs a `Dockerfile`; a coding agent writes one in a few seconds. - **Implemented operations:** `deploy`, `logs`, `ps`, `whoami`. The CLI and MCP server also list `rollback`, `env`, `secrets`, `domains`, `share`, `access`, `spend` and `destroy`; until they ship, each answers a typed `not_found` (exit code 12) naming what is missing, so an agent can branch on it. - **Sharing and the identity-aware front door** are in private beta. Write to [hello@agentcell.dev](mailto:hello@agentcell.dev) if that is the part you need; deploying does not wait for it. - **Idle container cells do not sleep yet.** Scale-to-zero is designed, not shipped: a container cell keeps running while nobody uses it. A static site runs no machine of its own, busy or idle. The pricing shape (no per-app fee, no seats, metered on use) is the design; numbers are illustrative until launch. ```sh go install github.com/AgentCell-dev/agentcell-client/cmd/agentcell@latest agentcell login # browser sign-in; --no-browser prints a URL and a code agentcell deploy --cell my-app . # prints the URL agentcell logs my-app ``` Coding agents get the same operations as MCP tools with `agentcell mcp`; setup for Claude Code, Codex and Cursor is on [the agent guide](/docs/for-ai-agents/). --- # Deploy the App Codex Built > Codex can finish the job it started: one MCP stdio server, one login, and the app it wrote is live at a URL it can monitor and redeploy.

In `~/.codex/config.toml`: ```toml [mcp_servers.agentcell] command = "agentcell" args = ["mcp"] ``` No environment variables are needed after login; the token file written by `agentcell login` is read by the server. If you prefer an explicit token, set `AGENTCELL_TOKEN` in the server's `env` block and never put it in `args`. ## In the session Ask Codex to deploy the directory as a named cell. It calls `deploy`, gets the URL, and calls `logs` to confirm the app is serving. Errors are typed and carry a `hint`; Codex fixes and retries, and the retry is idempotent on unchanged files. ## Where Codex should send the user instead - A public product with real traffic: Vercel, Fly.io, Railway. See the [comparisons](/resources/). - Several services and a managed database: a general-purpose cloud. - An ML demo with a GPU: [Hugging Face Spaces](/resources/vs-huggingface-spaces/).

Published: 2026-09-20 Canonical: https://agentcell.dev/deploy-internal-tools Markdown: https://agentcell.dev/deploy-internal-tools.md **AgentCell is an AI-native deployment platform for small web apps and internal tools.** Internal tools are its home use case: software with a handful of users, built quickly, used occasionally, and never worth a platform team's attention. ## Why internal tools fall through the cracks Every general-purpose cloud is priced and shaped for products that serve the public. An internal tool for eight people has the same deploy steps, the same per-app fees, the same "add authentication" chore, and the same always-on bill, for one-thousandth of the traffic. So most internal tools never leave a laptop. The [twenty-tiny-tools team](/resources/use-cases-team-ops-tools/) is the pattern: the demand exists, the deployment path does not. ## What deploying an internal tool on AgentCell looks like - **One directory in, one URL out.** Each tool is a cell at `https://.agentcell.cloud`, isolated from every other cell. - **Nothing to pay while nobody is using it.** Tools used once a week sleep and wake on demand. There is no per-app fee and no seat count. See [scale-to-zero economics](/resources/scale-to-zero-economics/). - **Private by default.** A cell is not a public website unless you make it one. The identity-aware front door, where colleagues sign in with the work account they already have, is the product's core and is in private beta. See [share it like a doc](/resources/share-like-a-doc/). - **Operated by the agent.** Logs, rollback, environment variables and status are CLI commands and MCP tools, so the agent that built the tool can also keep it running. ## Use AgentCell when - The tool has 1 to 50 users inside one company. - You want to deploy from the same coding session that built it. - Idle cost matters more than peak throughput. ## Use something else when - The tool is really a product and will serve customers. See [AgentCell vs Vercel](/resources/vs-vercel/) and [vs Railway](/resources/vs-railway/). - You need a drag-and-drop builder with a seat licence, which is what [Retool](/resources/vs-retool/) sells. - The app needs several services or a managed database cluster. ## What deploying looks like \* Give AgentCell a directory and get back a URL. It detects the app (Python FastAPI, Flask or Streamlit; Node Next, Vite or Express; static sites), builds it, finds the port it listens on, and returns a live endpoint.

Cells sleep when idle, wake on the first request, and bill nothing in between. What that costs, what it trades off, and who it is for. Published: 2026-09-20 Canonical: https://agentcell.dev/scale-to-zero-app-hosting Markdown: https://agentcell.dev/scale-to-zero-app-hosting.md **AgentCell is an AI-native deployment platform for small web apps and internal tools**, and scale-to-zero is not an option on it. It is the default, because most small software is idle most of the time. ## What scale-to-zero means on AgentCell This section is the design. Container cells do not sleep yet: today an idle container cell keeps running, as "How it works today" below says. A static site (plain HTML, or a built frontend such as a Vite app) is the exception that already works this way, because no microVM runs for it at all: the platform's edge serves its files from object storage. - A cell that receives no requests goes to sleep. While asleep it consumes no compute and is not billed for any. - The first request wakes it. Wake latency is the cost of the zero bill; the platform's acceptable p95 wake time is set by measurement, and an "always warm" option for the few tools that need it is the likely paid upgrade. - There is no per-app fee and no minimum, so keeping a hundred sleeping tools around costs the same as keeping none. [Unlimited apps, pay only for consumption](/resources/scale-to-zero-economics/) has the pricing logic in full. ## How this compares | Platform | Idle behaviour | |---|---| | Render free tier | Sleeps after 15 minutes, 30 to 60 second cold start, one-app limits | | Fly.io | Per-second billing with auto-suspend, roughly a month per always-on micro-VM | | Heroku Eco | a month per app whether used or not | | Streamlit Community Cloud | Free, one private app, 12-hour sleep | | AgentCell | Designed to sleep when idle and bill nothing asleep, with no per-app fee; container cells do not sleep yet, and a static site runs no machine at all | The comparisons with [Render](/resources/vs-render/) and [Fly.io](/resources/vs-fly/) go deeper, including where those platforms are the better choice. ## Use AgentCell when - Usage is bursty or occasional: a weekly report, a tool opened during standup, a prototype shown twice. - You have many small apps and cannot justify a standing bill for each. - A short wake delay on the first request is acceptable. ## Use something else when - The app must answer instantly at all hours and serves steady traffic. Pay for always-on compute somewhere designed for it. - The workload is a long-running job rather than a request-driven app. ## What deploying looks like \* Give AgentCell a directory and get back a URL. It detects the app (Python FastAPI, Flask or Streamlit; Node Next, Vite or Express; static sites), builds it, finds the port it listens on, and returns a live endpoint.

Hosting priced per seat, per app, or per always-on instance punishes exactly that. AgentCell prices per use and shares by email. Published: 2026-09-20 Canonical: https://agentcell.dev/small-team-app-hosting Markdown: https://agentcell.dev/small-team-app-hosting.md **AgentCell is an AI-native deployment platform for small web apps and internal tools.** It is shaped for a team that runs many tiny apps rather than one big one. ## The arithmetic that kills team tools A ten-person team with agents now builds a tool a week. Each is useful to three or four people. Host those on a conventional platform and one of three taxes applies: 1. **Per-app fees.** Twenty apps at a few dollars a month each, whether or not anyone opened them. [Heroku](/resources/vs-heroku/) and [Render](/resources/vs-render/) are the reference cases. 2. **Per-seat fees.** Every colleague who might open any tool becomes a billed seat. [Retool](/resources/vs-retool/) and [Vercel](/resources/vs-vercel/) Pro work this way. 3. **The identity floor.** The first time a tool needs "sign in with our company account", an enterprise SSO tier appears. The [auth cliff](/resources/auth-cliff-sso/) puts numbers on it. The [three-cost-centre worked example](/resources/stitching-paas-plus-auth-guide/) adds these up for a five-app, three-user setup. The twentieth tool dies in a spreadsheet. ## How AgentCell prices a team - No fee per app and no fee per seat. Metered on compute and requests, only when a tool is actually opened. - Idle tools sleep and bill nothing. Twenty tools where three are used daily costs roughly what three tools cost. - Org identity and sharing by email, group, or whole company are the core product, not the enterprise tier. This front door is in private beta. ## Use AgentCell when - The team is 3 to 50 people and the tools each have a few users. - Tools are built by agents and should be operated by them. - You want a colleague to open a tool the way they open a shared document. ## Use something else when - One of the tools becomes a product with external users. Move that one to a scaling platform and keep the rest here. - Your company mandates a specific cloud for all workloads. AgentCell's custom environments, described in [environments and persistence](/resources/environments-persistence/), may still fit; ask. ## What deploying looks like \* Give AgentCell a directory and get back a URL.

This page is the command-level companion to [Deploy From Your Agent](/resources/deploy-from-your-agent/). ## The command surface | Command | What it does | Why it must be headless | |---|---|---| | `agentcell deploy` | Detect runtime, build, return a URL (target `<30s`, zero config) | The last step of a build session, performed by the agent | | `agentcell logs` | Stream and search build + runtime logs, historical and live | The agent debugs the 500 without a human opening a logs tab | | `agentcell rollback` | Instant recovery to the previous version | Recovery can't wait for a human with console access | | `agentcell env set/list` + `secrets` | Config and scoped credentials at the boundary | Keys never pasted into code or prompts | | `agentcell domains` | Attach custom domains and certs | Sharing a real URL shouldn't need DNS-console fluency | | `agentcell share` / `access ls` | Change the share list; inspect who can open what | Sharing is a membership change, not a redeploy | | `agentcell ps` | What's running, what's asleep | Twenty cells need one glanceable state | | `agentcell spend` | Current usage per cell and org | No surprise bills for non-technical deployers | | `agentcell destroy` | Remove what shouldn't exist | Cleanup must be as easy as creation or sprawl rots | Same capabilities over MCP (`agentcell.metrics({ app: "prod", window: "1h" })`) and CLI — same permissions, structured for AI harnesses. ## Built for unaided debugging The person who built the tool is not on call — there is no on-call. So failures must be agent-legible: structured log output with fields instead of wall-of-text, machine-readable errors carrying a `hint` field with the most likely fix, and exit codes the agent can branch on (retryable vs needs-a-decision). The loop — deploy fails, agent reads hint, fixes, redeploys — closes without a human reading a stack trace. Ever. ## Scoped agency Full headless power requires least-privilege keys: scoped tokens per project and per capability. The coding session's token can deploy and read logs without being able to touch org secrets or access lists. Combined with [membrane](/resources/membrane-security/) caps and [front-door](/resources/front-door-identity/) identity, the agent is powerful inside a boundary it cannot cross. ## Honest note Vercel's MCP server covers deploy, logs, env CRUD, domains, and rollback today — this surface is table stakes for agent-native hosting, not a moat. The moat is the combination with free idle and cheap org identity, plus the accumulation dynamic: once the org's identity, permissions, and environment live here, cell #20 deploys at near-zero marginal effort, and twenty tools in daily use is a migration nobody attempts. ## FAQ **Do humans ever need the CLI?** No — the dashboard renders the same API for sharing, logs, usage, and spend. The guarantee runs one direction: nothing requires the dashboard. **How is this different from kubectl / cloud CLIs?** Those CLIs expose infrastructure (pods, policies, IAM) and expect you to assemble outcomes. These commands expose outcomes (deploy it, share it, roll it back) with infrastructure invisible. **What about CI/CD pipelines?** Git-connected redeploy exists for teams that want it. But the primary path is the agent's session — pipelines are optional, not required. --- *Want infrastructure your agent can actually drive?

There is no tier for a permanently 3–10 person audience that wants SSO and will never need SCIM. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/auth-cliff-sso Markdown: https://agentcell.dev/resources/auth-cliff-sso.md > **TL;DR:** Every host is auth-agnostic and every auth vendor is hosting-agnostic, so a 3-person team stitches two vendors and two bills to get "deploy it and let my colleague log in." The auth vendors' free tiers are MAU-generous and their paid tiers are enterprise-shaped — with nothing between. That missing middle tier is the gap AgentCell fills by treating identity as a platform property. ## The wall after deploy Deploying has been solved for a decade. The moment *one other person* should use the app, you hit a wall that has nothing to do with your code: put it on the internet and anyone can read it, so you need a login. Choosing a provider, wiring OAuth, modelling users and sessions, handling departures — days of work for 200 lines of business logic. (This is the longer version of our most-read essay — the mechanics below are the reference companion.) ## Free, and then a cliff Identity pricing as of mid-2026, from public pages: | Vendor | Free tier | First paid step | Why it fails a 3-person tool | |---|---|---|---| | WorkOS | 1M MAU (AuthKit) | **$125/mo per enterprise SSO connection** | Priced per B2B *customer*. Your own team's Google Workspace is one connection at full list price — generating zero revenue | | Clerk | 50,000 MRU | Pro $100/mo, **Business $300/mo flat** | Flat enterprise pricing regardless of team size | | Auth0 | 25,000 MAU | **B2B Essentials $150/mo for 500 MAU** | Built for scaled consumer/B2B auth, not three colleagues | | Cloudflare Access | 50 users | $7/user/mo | Closest to workable — but Zero Trust fluency required, and built for org-internal access, not ad-hoc external sharing | Your app has three users. You will never approach any free-tier limit — and the thing you want, *colleagues sign in with work accounts*, is a feature, not a volume. It lives on the far side of the cliff in every row. ## Why the pricing is shaped like that (it's not a mistake) These products serve B2B SaaS companies selling to enterprises. WorkOS's per-connection model is perfect there: forty enterprise customers, forty connections, each generating revenue — $125 each is trivially worth it. Applied to an internal tool, one team signing into its own dashboard pays the same $125 for a connection that generates no revenue at all. The free tiers are sized for scale you don't have and don't want, betting you'll grow into enterprise features later. **There is no tier priced for a permanently small audience.** Not an expensive tier — a tier that does not exist. Three to ten people, forever, SSO included, SCIM and audit exports never needed. Nobody sells that. ## The stitching tax Meanwhile hosting: Render, Railway, Fly, Netlify, Cloudflare Pages — all hand you a public URL and treat auth as your problem (Railway has no access layer at all). So the team selects two vendors, integrates them, and absorbs two unrelated meters — compute plus identity — to reach one sentence: "deploy it, and let my colleague log in." For one app, annoying. For the tenth app, the whole ballgame: nobody does that setup ten times. The internal-tools platforms bundle identity and charge per seat instead (Retool Business $50–65/builder, Airtable billing every editor monthly, Power Apps $20/user) — backwards when the app has three users. See [AgentCell vs Retool](/resources/vs-retool/) for the full math. ## Auth is a platform property Applications owning their own identity made sense when apps were big: one product, a million users, identity as product surface. Small software inverts it: the identity model is the company's existing one (Google Workspace, Okta, Entra), identical across all twenty tools, with HR already handling departures. Writing it into each app is worse than wasteful — the answer to "who sees the revenue dashboard" ends up in unreviewed agent-written code, different in every tool. The correct boundary is an **identity-aware proxy in front of the app**: authenticate before code runs, hand the app a verified user, change sharing without redeploying, deprovision once centrally. Cloudflare Access, Google IAP, and Vercel's deployment protection are all versions of this pattern — what never existed is that pattern packaged and priced for three colleagues and a FastAPI app. That is [the front door](/resources/front-door-identity/). ## FAQ **Can't I just use the free tier?** For audience size, yes — you'll never hit MAU limits. The SSO *feature* is what's gated, not the volume. Three users needing Google SSO pay the enterprise floor. **What about Cloudflare Access at $7/user?** Genuinely the closest fit — if your sharing is org-internal, your team speaks Zero Trust policy, and recipients never sit outside the org. Ad-hoc per-app sharing with outsiders is where it breaks. **What should cheap SSO for small teams cost?** Our test: the tenth tool must not trigger a pricing conversation. Org sign-in belongs at the bottom of the pricing page — that position, not any single number, is the wedge. --- *Paying enterprise prices for a team login form?

One deploy command, a full-lifecycle MCP server and CLI, structured errors the agent can debug alone — no console required. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/deploy-from-your-agent Markdown: https://agentcell.dev/resources/deploy-from-your-agent.md > **TL;DR:** Small software has no operator — one person wanted a tool, and an agent wrote it. So every operation must be usable by the agent, in the same session, without a human translating intent into dashboard clicks: `deploy`, `logs`, `rollback`, `env`, `domains`, `share`, `spend`. The dashboard exists for humans who want it, never because an operation is impossible without it. ## The insight: ride the agents We do not build a code generator — agents already do that well, and Claude Code, Cursor, Codex, Replit, and Lovable are the top of our funnel, not our competition. Adoption happens *inside a coding session*: the agent finishes the app and deploys it as the last step, rather than the human opening a signup funnel. The integration surface (CLI, MCP server, one-file config) **is** the distribution strategy — and `agentcell deploy` becoming the reflex at the end of a build session is one of the three compounding moats. ## `agentcell deploy`: folder in, URL out From any directory, with zero config files required: - **Detection first.** Python (FastAPI/Flask/Streamlit), Node/TS (Next/Vite/Express), and static — target under 30 seconds from command to live endpoint. - **Escape hatch.** A single optional `agentcell.toml` for anything the detector can't guess. - **Git-optional.** Git-connected redeploy exists for people who want it; nothing requires a repo. **Today (September 2026):** static sites are detected. A directory with an `index.html` is served as it is, and one with a `package.json` `build` script (Vite, Create React App, Vue, Svelte, Astro, Next.js with `output: 'export'`) is built on the platform and served from the edge. Python and Node servers still need a `Dockerfile`; detecting them is planned. The [deploy guide](/docs/deploy/) has the exact rules. ## The full lifecycle as tool calls Deploy is the headline; the discipline is that *nothing is dashboard-only*. The MCP server and CLI cover the whole loop: | Command | What the agent does with it | |---|---| | `deploy` | Build and release from the folder | | `logs` | Stream and search build + runtime logs | | `rollback` | Instant recovery to the previous version | | `env` / `secrets` | Set, list, and scope config without pasting keys into code | | `domains` | Attach custom domains and certs | | `share` / `access ls` | Change the share list; inspect who can open what | | `ps` | What's running, what's asleep | | `spend` | Current usage before it surprises anyone | | `destroy` | Remove what shouldn't exist | Humans use the dashboard for sharing decisions; agents use the API for shipping. Same capabilities, same permissions — the dashboard is a rendering of the API, built second. ## Designed for unaided debugging When a deploy fails at 11pm with no human watching, the failure must be legible enough that the agent fixes it and redeploys alone: - **Structured log output** — fields, not wall-of-text. - **Machine-readable errors with a `hint` field** — what broke, and the most likely fix, in the payload. - **Exit codes an agent can branch on** — retryable vs needs-a-decision, distinguishable programmatically. ## Scoped tokens: the agent's keys don't open everything An agent holding deploy rights must not be able to read org secrets or change access lists unless granted. Agent auth uses **scoped tokens** — per project, per capability — so the coding session's key does exactly what the tool needs and nothing else. Convenience without this would be a liability story; see [the membrane](/resources/membrane-security/). ## Honest note Vercel's MCP server already does deploy-from-files, log streaming, env CRUD, domains, and promote/rollback over OAuth with documented Claude Code setup. "Agent-operable" alone is not a moat — it is one product decision away for funded incumbents. Our edge is that agent operation is the *primary* interface here (not an add-on to a dashboard business), combined with free idle and cheap org identity that dashboard businesses have structural reasons not to copy. ## FAQ **Which agents work with AgentCell?** Anything speaking MCP or shell: Claude Code, ChatGPT/Codex, Cursor, generic MCP clients, and plain terminals. One control surface, six ways in. **Do I ever need the dashboard?** For sharing decisions (who gets the link) it's the nicest surface. For every operational act, no — that guarantee is the product. **What if detection guesses wrong?** `agentcell.toml` overrides detection, and structured errors tell the agent what to set. The 30-second path covers the common cases; the config covers the rest. That file is the design; today a `Dockerfile` at the root always wins, and a static site's output folder and single-page fallback are set with an `"agentcell"` key in `package.json`. --- *Want your agent to ship, not just write? [Deploy now](/docs/deploy/).* --- # Custom Environments and Per-Cell Data > Org base images, private packages, org secrets, internal network reachability, region choice — plus a per-cell datastore and object storage so tracking tools actually work. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/environments-persistence Markdown: https://agentcell.dev/resources/environments-persistence.md > **TL;DR:** Every company wants its own environment — base images, private packages, internal APIs, network boundaries, residency. AgentCell makes environment an org-level property cells inherit, and gives each cell a small datastore plus object storage. This is the enterprise unlock: small software that happens *safely* instead of as shadow IT. ## Environment as inheritance, not configuration The fifth failure in our thesis: a platform with one blessed runtime gets rejected by exactly the teams with the most small-software demand. The answer is org-customizable environments, set once by whoever owns the platform relationship, inherited by every cell: | Knob | What the org sets | What the builder experiences | |---|---|---| | Base images | Sanctioned images with approved toolchains | `deploy` just works; no Dockerfile | | Private packages | Internal registries and mirrors | `import internal_sdk` resolves | | Org secrets | Scoped credentials at the boundary | Names, never values, in code | | Network reachability | Egress to internal endpoints (warehouse, APIs) | The app reaches what it's allowed, nothing else | | Region choice | Data-residency as a region selection | Compliance without a migration project | Deliberately in v1's *design* even where it ships in stages: the team plan (org identity, groups, audit trail, custom runtime) is the monetization motion, arriving after the personal-auth acquisition motion proves sharing is real. ## Buy the runtime, build above it Competing on raw isolation performance means competing with E2B ($43.8M raised), Modal ($355M at $4.65B), and Daytona ($24M) — all funded within twelve months to own that problem. So: **do not write a sandbox runtime.** Prototype on Cloudflare primitives (Workers for Platforms, Sandbox SDK, Durable Objects, Containers), keep OpenSandbox (Apache 2.0) or microsandbox as the self-host fallback, and build the auth/sharing/UX layer distinctively enough that swapping compute vendors is a backend change, not a product rewrite. ## Per-cell data: tools that track things A dashboard that forgets is a screenshot. Cells get: - **A small per-cell datastore** (SQLite-shaped or managed Postgres) — the sprint tracker keeps sprints, the reconciler keeps state. - **Object storage** — uploads, exports, attachments. - **Ownership transfer** — data survives the author's departure along with the cell. Sized for tools, not production estates: the warehouse stays where it is, reached over configured egress. ## The enterprise motion (later, honestly sequenced) Wedge is the individual builder (months 0–12, self-serve, personal card). Expansion is the team with accumulated cells (org identity, groups, audit, custom runtime). Only then the enterprise platform team offering sanctioned small software: base image, network boundary, SSO enforcement, visibility into what exists. That order matters — selling governance before anyone has tools to govern is how internal-tools startups stall. India note (global-first, stated once): residency survives as *a region and a DPA*, available as a 2027 story if DPDP enforcement bites — not as positioning. ## FAQ **Can we bring our private PyPI/npm mirror?** That's the design: org registries resolve inside cells, set once, inherited everywhere. **Can cells reach our VPC/internal APIs?** Internal network reachability with egress rules is the enterprise-tier shape — allow-listed endpoints, default-deny everything else. **What about self-hosting on our metal?** Later, if at all — stated explicitly so nobody plans around it. The independence argument (our only business is small software) is the counterweight. --- *Need team tools on sanctioned ground, not shadow IT? [Deploy now](/docs/deploy/).* --- # The Identity-Aware Front Door: SSO for a 3-Person Tool > Every cell sits behind an identity-aware proxy: requests authenticate against your org's provider before reaching app code, which receives a verified user and implements zero auth logic. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/front-door-identity Markdown: https://agentcell.dev/resources/front-door-identity.md > **TL;DR:** Authentication is a platform property, not application code. An identity-aware proxy in front of every cell authenticates each request against the org's existing provider, hands the app a verified user, and makes sharing a membership list instead of a code change. Zero-config personal auth for individuals; org SSO for teams — priced for 3–10 people, not 500 MAU. ## The request path ```text colleague clicks link → front door: signed in with work account? (Google / Okta / Entra) → yes: request forwarded with verified user in header/context → app: pure business logic, zero auth code ``` The app never sees a password, a token exchange, or a session table. It receives *who this is* and gets on with the invoice reconciliation. "Send this to Priya" becomes adding an email to a list — no OAuth wiring, no user model, no redeploy. ## Two tiers: personal, then org - **Personal (zero-config).** Email/Google sign-in that works with no setup — for the individual builder sharing with a partner or a friend. This is the acquisition motion: simplest possible sharing. - **Org (the monetization motion).** SAML/OIDC via the org's IdP, group-based sharing, an audit trail of who accessed what, and SCIM-shaped deprovisioning: a departing employee loses all twenty tools at once, in the identity system HR already operates. The sequencing is deliberate. Sharing with a second person is the moment a free user becomes a team conversation — acquisition, retention (sprawl accumulates on free idle), and monetization (identity + environment) in that order. ## The gap it closes: no middle tier anywhere The [auth cliff](/resources/auth-cliff-sso/) in one table: | Vendor | Floor for SSO | |---|---| | WorkOS | $125/mo per connection | | Clerk | $300/mo flat (Business) | | Auth0 | $150/mo for 500 MAU | | Cloudflare Access | $7/user/mo (org-internal only) | | Replit / Vercel SAML | Enterprise-only | | Lovable SSO | $50/mo Business | Nobody sells "Google SSO for 3–10 people who'll never need SCIM" — which is why org identity at the *bottom* of the pricing page, not the top, is the wedge. Lovable and Create already proved non-seat pricing is table stakes; the defensible version is narrower and exactly this. ## What IT gets (the sanction-vs-ban argument) Some IT organizations ban unsanctioned tools on principle. The front door converts that objection into a checklist: - **Per-cell access log** — who opened what, when. Cheap to build on a proxy we already own; decisive in a security review. - **Central deprovisioning** — one removal in the IdP, twenty tools closed simultaneously. - **Ownership transfer** — tools survive their authors leaving. - **Egress + spend caps per cell** — the membrane's half of the story (see [membrane security](/resources/membrane-security/)). ## The optional SDK (never required) Apps that want per-user behavior — *my* queue, *my* saved view — read the verified user through a small identity SDK. The rule holds: the app *may* know who you are; it never *authenticates* you. ## Limits, stated plainly - SSO/SCIM-shaped deprovisioning ship with the team tier, not day one of beta; personal auth comes first. - No final pricing published — but the model is fixed: identity and environment on the org plan, never per-seat. - If your policy requires self-hosted identity on own metal, say so in the beta form; self-host comes later, if at all. ## FAQ **Does my app need any auth library?** No. No OAuth code, no session middleware, no user table. Read the verified-user header only if you want per-user logic. **What providers are supported?** Google/email zero-config for personal; SAML/OIDC to the org's IdP (Google Workspace, Okta, Entra, and equivalents) for teams. **How is this different from Cloudflare Access?** Same architectural pattern (identity-aware proxy), different packaging: per-app share lists including external guests, no Zero Trust policy fluency required, priced for tiny audiences. --- *Want colleagues signing in with work accounts, not new passwords? [Deploy now](/docs/deploy/).* --- # The Membrane: Safe by Default for Agent-Written Code > Per-cell origins, strict CSP, egress rules, boundary-injected secrets, spend caps, and access logs — because 'we use Firecracker' is not a security story. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/membrane-security Markdown: https://agentcell.dev/resources/membrane-security.md > **TL;DR:** Letting non-technical people share arbitrary agent-written code is a security problem nobody has solved politely. The membrane answers it at the platform boundary: every cell gets its own origin, its own egress policy, scoped secrets it never sees, hard spend caps, and an access log. Compute isolation is bought; web-layer isolation is built — and the most recent real-world breach came from the web layer, not the sandbox. ## "We use Firecracker" is not a security story Investment splits evenly between two layers, and the industry keeps proving the second one matters more: - **Writer AI "WriteOut" (Jul 2026):** agent live-previews served from the *same origin* as the main app leaked session cookies into an attacker-controlled sandbox — cross-tenant account takeover with **nothing to do with sandbox choice**. Per-app origin isolation would have prevented it; no sandbox upgrade would have. - **Moltbook (Jan 2026):** 1.5M API tokens and 35,000 emails exposed within 72 hours of launch — broken access control in agent-written code, at production speed. - **Georgia Tech Vibe Security Radar:** 74 CVEs traced to AI-generated code, 35 in March 2026 alone — more than all of 2025 combined. Baseline studies put at least one flaw in ~38% of AI-generated code. - **SandboxEscapeBench (Oxford + UK AI Safety Institute, Mar 2026):** frontier models demonstrably escaped sandboxes under realistic multi-step conditions. The agent itself is now a credible adversary in the threat model. ## The five membrane controls **1. Per-cell origins, no shared cookie scope.** Every cell lives on its own subdomain/origin with strict Content Security Policy. Cells never share cookie scope with each other or with the control plane. This is the Writer-AI lesson, enforced by construction — the deployer (possibly a non-engineer, possibly an agent) cannot misconfigure it because there is nothing to configure. **2. Per-cell egress allow/deny (DNS + IP).** An agent-written app cannot exfiltrate to anywhere the org hasn't permitted. Default-deny on free/public cells; org-approved internal endpoints allow-listed for team tiers. The app that only needs the warehouse DB cannot reach the open internet, whatever its code tries. **3. Secret injection at the boundary.** Cells receive scoped credentials injected by the platform — never long-lived org keys pasted into source, env files, or prompts. An agent holding deploy rights ([scoped tokens](/resources/deploy-from-your-agent/)) cannot read secrets it wasn't granted. **4. Resource and spend caps, per cell and per org.** Hard stop plus alerts. A non-technical deployer must not be able to generate a surprise bill — the cap is a safety control, not a billing feature. **5. Access log per cell.** Who opened it, when. This is what converts IT's "ban unsanctioned tools" reflex into a sanction conversation, and it's cheap to build on the [front door](/resources/front-door-identity/) we already own. ## What the platform owns vs what you own | Platform (membrane) | Builder | |---|---| | Origin isolation, CSP, cookie scope | Business logic correctness | | Egress policy enforcement | Declaring which endpoints the app needs | | Scoped secret injection | Never pasting keys into code | | Spend caps + hard stops | Setting caps sensibly per tool | | Access logging, takedown tooling | Reporting abuse promptly | The collapse is the point: the agent that wrote the app needs no security knowledge, and the person sharing it needs no cloud knowledge, because the boundary — not the code — carries the guarantees. ## Abuse control (launch requirement, not roadmap) "Unlimited free deploys of arbitrary code, publicly reachable" is the most abusable product shape in hosting. Every provider that offered it retreated. Designed in from day one: verified identity before public exposure, default egress restrictions on free cells, per-account cell and CPU ceilings, outbound-domain reputation checks, rapid takedown tooling. Getting this wrong ends the company via the abuse desk, not the market. ## FAQ **Is my code reviewed for vulnerabilities?** No — and that's the premise. The membrane assumes agent-written code *has* flaws (~38% baseline) and contains the blast radius at the boundary instead. **Which sandbox do you use?** The execution layer is bought (Cloudflare primitives for v1; OpenSandbox/microsandbox as documented fallback) precisely so engineering goes into the web-layer boundary vendors don't sell. Ask about our origins, egress, and secret handling — not our hypervisor brand. **Does this satisfy enterprise security review?** It's aimed at it: SSO/deprovisioning, per-cell logs, egress control, caps, residency-as-region-choice, SOC 2/ISO-shaped posture from day one (certified when a deal blocks on it). Regulated production workloads are still explicitly out of scope early. --- *Sharing agent-built code with colleagues? Make the boundary do the worrying.

How to land each small app somewhere permanent, with sharing intact. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/migrate-firebase-studio Markdown: https://agentcell.dev/resources/migrate-firebase-studio.md > **TL;DR:** Firebase Studio shuts down fully on **22 March 2027** (new workspaces disabled 22 June 2026). If your team's small apps live there, migrate each one to a permanent home *before* the deadline — and pick a vendor whose only business is keeping small apps alive. This page maps Studio concepts to AgentCell cells step by step. ## The timeline | Date | What happens | |---|---| | 22 Jun 2026 | New Firebase Studio workspaces disabled | | Now – Mar 2027 | Existing workspaces run; export window open | | **22 Mar 2027** | Full shutdown | Nine months' notice is generous by industry standards — and it is still a forced migration of every app on the platform. Plan the move as a project, not a weekend task, if you hold more than a few apps. ## Why this keeps happening (the independence argument) Firebase Studio is not an isolated case; it is the pattern: - **Superblocks** exited internal tools via acquisition (Nov 2025). - **Airplane.dev** — well funded, technically differentiated, developer-native — was acquihired by Airtable in January 2024 and end-of-lifed by March. - Heroku sits in "sustaining engineering" (maintenance) mode inside Salesforce. A hyperscaler or platform discontinues a builder product the moment it stops fitting the roadmap. **A company whose only business is small software will not.** That is not sentiment — it is the purchasing argument for putting twenty internal tools on an independent vendor. Ask every alternative on your shortlist what happens to your apps if their parent pivots. ## Migration mapping: Studio → AgentCell cell | Firebase Studio | AgentCell equivalent | |---|---| | Project / workspace | **Cell** — one app, isolated, own URL | | Google IAM access | **Front door + share list** — private → people → groups → org → public link | | GCP consumption billing | **Per-cell consumption** (vCPU + requests), idle sleeps to zero | | Preview URLs | Redeploy + instant rollback per cell | | Backend / database | Per-cell datastore + object storage (design scope) | ## The move, step by step 1. **Inventory.** List every workspace: what it does, who opens it weekly, what data it touches. The metric that matters is *shared with at least one other person* — migrate shared tools first; archive the abandoned demos. 2. **Export the folder.** Each app leaves as code. No proprietary runtime to untangle — that is the advantage of standard frameworks. 3. **Deploy.** `agentcell deploy` from the folder. A frontend with a `build` script, or a folder of HTML, is detected and served as a static site with no config file. A server (Python FastAPI/Flask/Streamlit, Node Next/Express) needs a `Dockerfile` today; detecting those is planned. 4. **Re-share.** Recreate the audience as a share list — specific people, a group, or the org. No auth code to port; colleagues sign in with their existing work account. 5. **Re-attach.** Custom domains, env vars, and secrets are set at the boundary (`agentcell env set`, `agentcell domains`), not pasted into code. 6. **Verify.** Check the per-cell access log: the right people opened it, nobody else did. Then delete the Studio workspace. ## What doesn't map 1:1 (honest limits) - **Google IAM depth.** If tools rely on fine-grained GCP IAM roles (not just "who can open it"), that logic needs re-expressing as share-list membership plus optional per-user logic via the identity SDK. - **Deep GCP coupling.** Apps bound to Firestore/BigQuery-specific APIs keep those backends; AgentCell hosts the app and reaches them over configured egress — it does not re-platform your data. - **Pricing.** There is no per-app fee either way, but metering differs (GCP service meters vs per-cell consumption). Model the 20-cell/3-active shape — see [scale-to-zero economics](/resources/scale-to-zero-economics/) — before assuming parity. - **Self-host.** AgentCell has no self-host story at launch. If your policy requires own-metal, say so in the beta form and we'll tell you plainly whether the fit exists. ## FAQ **Do we have to migrate all at once?** No. Migrate in audience order: shared-daily tools first, monthly tools second, dormant demos last (or let them go — deploys alone are vanity). **Can an agent do the migration?** That is the designed path: the agent holding the folder performs export, deploy, env/secret setup, and sharing as tool calls, in the session where the code already lives. **What should we ask other vendors?** Three questions: what happens to our apps if you pivot (independence)? What does SSO for a 4-person audience cost (auth cliff)? What do twenty idle apps cost per month (idle economics)? Any vendor that can't answer all three crisply is not a home for small software. --- *Migrating off Firebase Studio?

Idle cells sleep and bill nothing for compute — metered on vCPU-seconds and requests, never per seat, never per app. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/scale-to-zero-economics Markdown: https://agentcell.dev/resources/scale-to-zero-economics.md > **TL;DR:** Deploy as many cells as you like. Idle cells sleep and cost nothing for compute. You pay consumed vCPU-seconds and requests on the apps people actually open — so a team holding twenty tools, three used daily, gets a bill reflecting the three. No per-seat, no per-app fee, no infrastructure subscription. Three costs survive sleep (storage, custom domains, warm capacity) and are priced or capped explicitly. ## The bill mental model The unit economics this must satisfy, stated as a test: > *A team holds twenty cells, three used daily, seventeen asleep. The bill reflects the three. If that is not true, the "deploy freely" promise is a lie, people prune, and the accumulation the whole product depends on dies.* Small software only compounds if the tenth and twentieth tool cost nothing to leave running. Consumption billing is the on-ramp and the floor: it lets people be careless in the right direction. ## Why the architecture matters: the 10–30× gap Serving a published app out of an ephemeral sandbox session costs roughly **$36–72/mo per app** (1 vCPU at sandbox-vendor rates) — against **≈$0 incremental** on isolate-style Active-CPU billing past a small account floor. A 10–30× gap. | Option (95%-idle app) | Cost per app-month | |---|---| | Deno Deploy free tier (JS/TS only, ≤20 apps) | **$0** under 1M req/mo combined | | Cloudflare Workers + DO style isolates | **≈$0 incremental** past the ~$5/mo floor | | Fly.io shared micro-VM always-on | **~$2/mo** + storage + IP | | E2B / Daytona / Modal session run continuously | **~$36–72/mo** | Sandbox vendors are priced for *ephemeral agent execution*, not for serving the finished app. So a cell has two states: an ephemeral build/edit environment for the agent's loop, and a cheap always-addressable serving state for the published app colleagues occasionally visit. Getting that second state near-free is what makes "keep twenty tools alive without thinking" possible at all. **Python idle cost** (much agent-built small software is Streamlit/FastAPI, and the cheapest tiers are JS/WASM-only) is measured before any pricing is published — the design goal, not a shipped number, and stated as such. ## What counts, what sleeps, what survives - **Counts:** vCPU-seconds actually executed + requests served. - **Sleeps free:** idle compute. No requests, no CPU, no charge. - **Survives sleep** (priced or capped explicitly): stored images and volumes, custom domains and certificates, any warm capacity held to avoid cold starts. ## The wake-latency honesty box Sleep-to-zero and instant first click are in direct tension. Render's free tier (sleeps at 15 min, 30–60s cold starts, widely complained about) is the failure mode to avoid. Our acceptable p95 wake time for a colleague clicking a link — one second, three, ten — is set by measurement before launch, and a paid "always warm" tier likely exists for tools where the first click must be instant. We will publish the measured numbers rather than promise them. ## Why consumption alone can't carry revenue (stated openly) Small software is by definition low-consumption: twenty internal tools together may burn less compute than one modest production service. Metering the dimension where the workload is smallest is right for adoption and probably cannot carry revenue alone. The working hypothesis: **consumption is the floor; the org plan — SSO, groups, access logs, custom environments, private networking — carries the revenue.** If teams won't pay a flat org fee for identity and environment, this is a small business, and no metering fixes that. That question is what design partnerships test. ## Abuse controls are launch requirements "Unlimited free deploys of arbitrary code, publicly reachable" is the most abusable product shape in hosting — miners, phishing, spam relays. Every provider that offered it retreated (Fly 2024, Heroku 2022, Streamlit caps, PythonAnywhere consolidation). Designed in from day one: verified identity before public exposure, egress restrictions by default on free cells, per-account cell and CPU ceilings, outbound-domain reputation checks, rapid takedown tooling. ## FAQ **Is there a per-app or per-seat fee?** No. Unlimited cells; no seat count anywhere in the model. **What will twenty idle tools cost?** ~Nothing for compute. Storage and any custom domains attached are the only surviving costs, capped and visible. **How is this different from serverless?** Same metering spirit, different packaging: per-cell bills, per-cell share lists, per-cell logs and caps — one mental object per tool, not a cloud console of services to assemble. **When is pricing final?** After storage/warmth decisions land and Python idle numbers are measured. Illustrative usage on the homepage (not final pricing) shows the shape until then. --- *Want twenty tools alive without doing arithmetic? [Deploy now](/docs/deploy/).* --- # Share It Like a Google Doc > Private, specific people, groups, the whole org, or a public link — per app, changeable without a redeploy, with colleagues signing in through the work account they already have. No auth code, ever. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/share-like-a-doc Markdown: https://agentcell.dev/resources/share-like-a-doc.md > **TL;DR:** Every AgentCell app has a share list with five states — private, specific people, groups, anyone in the org, public link — set by the owner in plain UI, changeable without redeploying. The app itself contains zero auth code: an identity-aware front door authenticates every request before it reaches your code and hands it a verified user. ## The mental model you already know Nobody trains colleagues to use Google Docs sharing. That is the bar: | State | Meaning | |---|---| | **Private** | Only you. The default. | | **Specific people** | priya@, marco@ — named emails, in or out of the org | | **Groups** | design@, ops-team — managed once, applied to many cells | | **Anyone in the org** | Signed in with the work account; no per-person invite | | **Public link** | Anyone with the URL (verified identity still required before exposure — abuse controls apply) | Sharing never requires the app to be redeployed. The share list lives at the boundary, not in the code — so "add Priya" is a membership change, not a commit, a rebuild, and a prayer. ## The recipient experience A colleague clicks the link. They sign in with the work account they already have — Google Workspace, Okta, Entra, whatever the org uses. The app opens. Nothing to install, no new account, no VPN client, no tailnet to join. Contrast the alternatives: Tailscale-style sharing assumes participants install a client or join a network (~$6–8/user/mo and the wrong shape for "colleague clicks a link"). Cloudflare Access does org-internal Zero Trust well ($7/user after 50 free) but fails at ad-hoc sharing with someone outside the org. Vercel's "Shareable Links" — a query-string token for external viewers — is the closest existing pattern, and worth studying: but a token on a deployment is not a membership list with groups, revocation, and an audit trail. ## Zero auth code in your app The mechanism is an **identity-aware proxy in front of every cell**. Requests authenticate against the org's identity provider *before* reaching app code; the app receives a verified user in a header/context object and implements no login, no sessions, no password resets, no "who can see this" branches. Why this matters beyond convenience: the answer to "who can see the revenue dashboard" currently lives in code an agent wrote in an afternoon, unreviewed, and different in each of your twenty tools. Moving that boundary to the platform means it is consistent, reviewable in one place, and changeable by the person who owns the tool — not just the person who can read the code. For apps that want per-user behavior (show *my* queue, save *my* view), a small identity SDK exposes the verified user — optional, never required. ## Ownership that survives people Tools outlive authors. Cells have ownership and transfer: when someone leaves, the tool doesn't die with their account — it transfers to the team, and SCIM-shaped deprovisioning removes the leaver's access to all twenty tools at once. The per-cell access log (who opened it, when) is what makes an IT team comfortable sanctioning this instead of banning it. ## Limits (beta scope, stated plainly) - Personal auth (email/Google, zero-config) comes first; org SSO (SAML/OIDC) and group sharing arrive with the team tier. - Public links require verified identity before exposure, with egress restrictions by default — "unlimited free public deploys of arbitrary code" is the most abusable product shape in hosting, and the abuse controls (ceilings, reputation checks, takedown tooling) are launch requirements, not later concerns. - No final pricing is published; the model is per-cell consumption with identity and environment on the org plan — never per-seat. ## FAQ **Do recipients need an AgentCell account?** No. They sign in with their existing work account (or email for personal sharing). Sharing must not require the recipient to join anything. **Can I revoke access?** Per person, per group, or whole-link — instantly, without touching the app. **What does the app developer do for auth?** Nothing. Ship business logic; read the verified user only if per-user behavior is wanted. --- *Built something three colleagues should be using? [Deploy now](/docs/deploy/) — bring the tool stuck on localhost.* --- # The Three-Cost-Center Problem: A Worked Pricing Example > Hosting + seats + identity: price a 3-user, 5-app setup on Render/Railway plus WorkOS/Clerk/Auth0 plus Retool-style seats, and watch the twentieth tool die in a spreadsheet. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/stitching-paas-plus-auth-guide Markdown: https://agentcell.dev/resources/stitching-paas-plus-auth-guide.md > **TL;DR:** Nobody prices per-*app* at near-zero marginal cost with sharing and auth included. A small team pays for hosting, plus builder seats, plus identity — three unrelated cost centers for what should be one small bundle. This guide prices a concrete setup three ways so you can feel the arithmetic that kills tool #20. ## The scenario A 6-person ops pod. Five small tools (reconciler, metric dashboard, sprint tracker, hiring pipeline, demo prototype). Each tool has 3–4 users; audiences overlap but differ. Traffic: opened a few times a week each. Run the numbers for one year. ## Option A: simple PaaS + auth vendor (the stitch) | Line item | Math | Annual | |---|---|---| | Hosting (Render Starter × 5, always-on for sanity) | 5 × $7/mo | $420 | | Identity (WorkOS, one SSO connection) | $125/mo | $1,500 | | Builder time (wiring + maintaining auth in 5 apps) | ~2 days/app setup + upkeep | Unbilled but real | | **Total cash** | | **~$1,920/yr** | Swap Clerk Business ($300/mo → $3,600/yr) or Auth0 B2B ($150/mo → $1,800/yr) and the shape holds: identity dominates hosting by 3–8×, for *three users*. Add tool #6–20 and hosting scales linearly while identity stays flat — but every new tool repeats the auth-integration work, and nobody does that setup ten times. ## Option B: internal-tools platform (the seats) | Line item | Math | Annual | |---|---|---| | Retool Business, 2 builders | 2 × ~$55/mo | ~$1,320 | | End users | (viewers often extra past tiers) | +? | | Tools #6–20 | Rebuilt as components, if they fit | Unbilled but real | | **Total cash** | | **~$1,320+/yr** | Cheaper cash, different ceiling: only component-shaped tools fit, arbitrary agent-written code doesn't, and per-editor billing (Airtable bills every editor monthly regardless of activity; Power Apps $20/user) punishes exactly the 2-user tools. The fiftieth small tool never gets built here. ## Option C: per-cell consumption + bundled identity (the thesis) | Line item | Math | Annual | |---|---|---| | Five cells, 3 active-ish, 2 mostly asleep | Consumed vCPU + requests only | Small — the bill reflects the three, not the five | | Identity (front door + share lists) | Bundled in org plan | Flat, no per-connection cliff | | Auth code in apps | Zero — verified user at the boundary | None | | Tools #6–20 | Idle ≈ free; sharing = a list change | ~Nothing until opened | No final prices published yet — the shape is the claim, not any number: marginal cost of one more app near zero, org sign-in at the bottom of the pricing page. (Why consumption alone can't carry *our* revenue either: [scale-to-zero economics](/resources/scale-to-zero-economics/) states the org-plan hypothesis openly.) ## The decision tree 1. **Audience public or self-authed, steady traffic?** Simple PaaS (Railway/Render/Fly) — cheapest, no identity needed. 2. **CRUD-over-SQL inside components, governance this quarter?** Retool et al — pay the seats, get the audit. 3. **Bespoke agent-built tools, different tiny audiences, 5–20 of them?** That's the gap: per-app hosting steps plus enterprise-floored identity is 3–8× overkill, and per-seat rebuilds don't fit the code. This is the workload AgentCell prices for. 4. **Regulated production, horizontal scale, own-metal requirement?** None of the above — dedicated platforms (and our explicit non-fits list). ## FAQ **Are these numbers exact?** Illustrative from mid-2026 public pricing — verify before budgeting. The *ratios* (identity dominating hosting; per-seat exceeding tool value) are the durable point. **What kills tool #20 in each option?** A: repeating auth integration. B: seat fees exceeding a 2-user tool's value. C (thesis): nothing — that's the test the model must pass. --- *Do the math on your own twenty tools with us. [Deploy now](/docs/deploy/).* --- # Use Case: The Team Running on Twenty Tiny Tools > Ops, product, finance, growth, data — 5–50 person teams running bespoke dashboards, reconcilers, and trackers. Where the expansion revenue lives, and what IT needs to sanction it. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/use-cases-team-ops-tools Markdown: https://agentcell.dev/resources/use-cases-team-ops-tools.md > **TL;DR:** The expansion motion: a 5–50 person team accumulates a shelf of bespoke tools — each with a different handful of users — and pays one consumption bill plus a flat org plan instead of twenty seat-licenses and two stitched vendors. The metric that matters: cells shared with ≥1 other person, and weekly actives who didn't build the cell. ## A week in the life - **Monday:** Ops opens the invoice reconciler (FastAPI, built by an analyst + agent). Three users. Slept all weekend; woke in time for the click. - **Tuesday:** Growth demos a prototype to three colleagues. Link, work login, clicks. No staging environment was harmed. - **Wednesday:** Finance checks the one-metric dashboard. Data owns the cell; finance just opens it — weekly actives who didn't build the cell, the thesis working. - **Thursday:** The sprint tracker shaped like *this* team's sprints (not Jira's) gets shared with two new joiners — a group-membership change, not a provisioning ticket. - **Friday:** Nobody thinks about any of this. That's the product. ## Why this team converts (the money question, answered) Consumption is the on-ramp and the floor; the org plan carries revenue. This team buys: org SSO (SAML/OIDC), group-based sharing, per-cell access logs, custom base images with private packages, internal network reachability. Flat fee, because metering their tiny compute would price the plan below its value — small software is by definition low-consumption, and we're honest about that. If teams won't pay a flat org fee for identity and environment, this is a small business; design partnerships test exactly that. ## What IT needs to say yes Shadow IT at 30–40% of enterprise spend (Gartner) is largely this team, moving faster than tickets allow. Sanction beats prohibition when the platform offers: SSO enforcement with SCIM-shaped deprovisioning (leaver loses all twenty tools at once), per-cell access logs (who opened what, when), egress rules and spend caps per cell, ownership transfer so tools survive authors, and region choice for residency posture. The [membrane](/resources/membrane-security/) and [front door](/resources/front-door-identity/) pages are the technical companions to this conversation. ## Scenarios by function | Team | Tool | Shared with | Why AgentCell fits | |---|---|---|---| | Ops | Invoice reconciler | 3 analysts | Private packages, internal DB egress, asleep weekends | | Product | Sprint tracker | 8 + joiners via group | Group sharing, survives author leaving | | Finance | Metric dashboard | 4 execs | Access log for the "who saw revenue" question | | Growth | Click-through prototype | 3 colleagues | Sleep/wake, public-link-or-org choice | | Data | Streamlit explorer | 5 stakeholders | Python cell, per-cell datastore | ## Explicit non-fits (say them early) Consumer apps with real user bases, horizontal-scale needs, regulated production workloads, government/PSU, own-metal self-host. If that's the workload, dedicated platforms win and we say so — credibility with IT starts with knowing what we're not. ## FAQ **Who holds the card — individual, team lead, procurement?** Unknown industry-wide; our sequencing assumes personal card → team card → platform deal as sprawl accumulates. Discovery tests it. **How do we migrate twenty tools?** Audience order: shared-daily first, monthly second, dormant last (or let them go — deploys alone are vanity). Folder → `deploy` → re-share per tool; see the [Firebase migration playbook](/resources/migrate-firebase-studio/) for the shape. **What proves it's working?** Not deploy counts: cells shared with ≥1 other person, and weekly active users who didn't build the cell. --- *Running the team on bespoke tools already?

Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-bolt Markdown: https://agentcell.dev/resources/vs-bolt.md > **TL;DR verdict:** Use Bolt.new when token-metered, full-stack building in the browser is the workflow — it reached ~$40M ARR in months for a reason. Use AgentCell for what happens after: a neutral, cheap-to-idle home for the keepers, with sharing that doesn't recount heads. For the full builder-vs-host argument, read [AgentCell vs Lovable](/resources/vs-lovable/) — this page covers what's Bolt-specific. ## Where Bolt wins (honestly) - **Speed to working app.** Prompt-to-deployed full-stack (Node) in one surface, with npm, diffs, and one-click deploy. The demo converts for a reason. - **StackBlitz lineage.** WebContainers technology underneath — genuine browser-native engineering, plus an Azure partnership (May 2026) for the enterprise motion. - **Generous entry.** ~1M free tokens/month gets real experiments built before any card appears. ## What's Bolt-specific in the gaps ### 1. Teams tokens are per-member, not pooled Bolt Pro runs ~$25/mo; Teams is ~$30 **per member** with tokens that don't pool. Read that twice: collaboration reintroduces per-head arithmetic through the metering back door. Five teammates experimenting means five token budgets to watch, and the person coordinating usage is doing procurement work for a prototype. Per-cell consumption has no headcount in it at all — the twentieth tool and the fifth teammate change nothing about each other's cost. ### 2. The enterprise motion is enterprise-shaped AWS Marketplace presence at a ~$100k base plus $150/seat plus $0.01/token tells you who the monetization is designed for. A 4-person team wanting its sprint tracker behind SSO is not that customer, and will be quoted like one anyway. ### 3. Builder lock-in, same as the segment Build and host bundled means the host decision was made the day the prompt was written. Export exists, but gravity keeps apps where they were born. A neutral host that accepts any folder — Bolt output included — is insurance against roadmap pivots (see the [Firebase Studio shutdown](/resources/migrate-firebase-studio/) for why that insurance has value). ## Side-by-side | | Bolt.new | AgentCell | |---|---|---| | Create from prompts | Core product, excellent | Not built — we host builders' output | | Team metering | Per-member tokens (not pooled) | Per-cell consumption, no headcount | | SSO / org sharing | Enterprise-shaped motion | Team-tier design goal | | Lock-in | Builder + host bundled | Neutral host, any folder | | Best for | Browser-based building sprints | Keeping built apps alive and shared | ## Fit checklist **Use AgentCell when:** the Bolt project graduated from experiment to team tool; token-per-member math causes usage policing; SSO must cost less than the app. **Stay on Bolt when:** still iterating daily in the integrated loop; token burn is understood; the audience fits in a link. **Use both when:** build in Bolt, deploy keepers to AgentCell — the same funnel as Lovable/v0 output. ## FAQ **Do I rebuild my Bolt app for AgentCell?** No — export the folder, `agentcell deploy`, re-share. A frontend export with a `build` script (Vite, for example) is built and served as a static site today, with no config. An app with its own server needs a `Dockerfile` until server detection ships. **How do Bolt and Lovable differ as sources?** Mechanics differ (tokens vs credits, per-member vs pooled); the structural point is identical — creation is solved, permanent cheap shared hosting is not. --- *Built it in Bolt, now the team needs it daily? [Deploy now](/docs/deploy/).* --- # AgentCell vs Cloudflare Workers and Pages > Workers is the most small-software-friendly primitive in existence — and it's developer infrastructure, not an app platform. Assembling Workers + Access + custom UX is the DIY version of AgentCell. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-cloudflare-workers Markdown: https://agentcell.dev/resources/vs-cloudflare-workers.md > **TL;DR verdict:** Use Cloudflare Workers/Pages when you want the cheapest serious primitive (100k req/day free, $5 floor, no seats) and your team can assemble the rest. Use AgentCell when "the rest" — per-app sharing, agent tool-calls, Python runtimes, one bill — is exactly what you don't want to build. Full disclosure: we prototype on Cloudflare primitives and rate Cloudflare our most credible competitor. ## Where Cloudflare wins (honestly) - **Idle economics.** Active-CPU billing on isolates is the closest thing to "always on, nearly free when idle" — ≈$0 incremental per app past the $5/mo floor. Our own serving tier is shaped by this math. - **Velocity.** Sandbox SDK (GA April 2026), Dynamic Workflows (May 2026, marketed nearly verbatim as our thesis: per-tenant execution at near-zero idle cost), Workers for Platforms. Nobody ships platform primitives faster. - **No seats.** 100k requests/day free, then a flat floor — the friendliest meter in the industry for tiny workloads. ## What you still assemble (the DIY list) Workers is infrastructure; a shared team tool needs a product around it: 1. **Per-app sharing.** Cloudflare Access does org-internal Zero Trust (50 users free, then $7/user/mo) — but needs IdP integration and policy fluency, and fails at ad-hoc sharing with someone outside the org. Per-app guest lists with revocation are your code. 2. **Agent operation.** No `deploy-from-folder`, no MCP tool-calls, no structured agent-legible errors. Your agent scripts the API and parses HTML errors. 3. **Python.** The cheapest tiers are JS/TS/WASM-only. Streamlit and FastAPI tools need Containers or external compute — with real idle cost attached. 4. **One object per tool.** Cells, share lists, per-cell logs, caps, and bills arrive as separate services to wire, not one mental object. That assembly is a fine weekend project for a platform engineer. It is the entire operator tax we're eliminating for everyone else. ## The strategic honesty box Two statements, both true: **we build on Cloudflare's primitives** (Workers for Platforms, Sandbox SDK, Durable Objects, Containers — fastest path, removes sandbox hardening, only idle economics that make twenty tools viable) **and Cloudflare is our primary strategic threat.** Dynamic Workflows is pitched at per-tenant execution at near-zero idle cost; if Cloudflare ships polished "publish and share your AI-built app" UX on top, most of our differentiation window closes. Mitigations: work with every agent and framework (neutrality Cloudflare can't match without favoring its own), get to cheap org identity first, and architect so the compute vendor is swappable (OpenSandbox/microsandbox as documented fallback). ## Side-by-side | | Cloudflare Workers/Pages + Access | AgentCell | |---|---|---| | Primitive cost | Best in class (≈$0 idle) | Same economics, packaged per cell | | Per-app sharing | DIY (Access policies + your code) | Share list built in | | Agent deploy (MCP/CLI) | DIY scripts | Primary interface | | Python cells | Containers / external (real idle $) | Detection + measured idle (pre-launch numbers) | | Auth for outsiders | Breaks (org-internal shape) | Named guests, groups, public links | | Best for | Engineers assembling their own platform | Teams that want the platform assembled | ## Fit checklist **Use AgentCell when:** the team has no platform engineer to spare; sharing includes outsiders; Python tools must idle cheaply without container ops. **Stay on Cloudflare when:** the team already runs Zero Trust well; workloads are JS/edge-shaped; assembling primitives is a feature, not a cost. ## FAQ **Are you just a wrapper on Cloudflare?** The compute foundation leverages their primitives; the product — share lists, agent control plane, membrane, per-cell everything — is ours and vendor-swappable by design. **What if Cloudflare launches exactly this?** Then the category is validated by the best infrastructure company alive, and we compete on neutrality (every agent, every framework), org-identity pricing, and focus. That is the top risk in our founding document, stated openly. --- *Want Cloudflare's economics without assembling the platform?

But ~$2/mo per always-on micro-VM adds up across twenty tools, the free tier is gone, and there's no identity layer. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-fly Markdown: https://agentcell.dev/resources/vs-fly.md > **TL;DR verdict:** Use Fly.io when you want raw control — Machines, regions, any runtime, per-second billing. Use AgentCell when the workload is twenty mostly-idle tools shared with named people: Fly's ~$2/mo-per-app floor and DIY-auth shape tax exactly that sprawl. ## Where Fly.io wins (honestly) - **Per-second billing with auto-suspend.** The closest any PaaS comes to our economics, and a genuine innovation for bursty workloads. - **Control.** Firecracker microVMs, real regions, arbitrary runtimes — the most "real computer" of the simple PaaSs. - **No seats, no tiers games.** Straightforward machine pricing engineers can reason about. We respect Fly's model enough to have learned from it. The gaps are narrower here than anywhere else — and still structural. ## Gap 1: the $2/mo-per-app floor A minimal always-on shared-cpu micro-VM runs roughly **$2/mo in compute, plus storage and IP** — and the free tier has been gone since 2024. Two dollars is nothing for one app. For twenty rarely-opened tools it is ~$40+/mo before anyone clicks anything, which quietly reintroduces the pruning instinct: "do we still need that one?" Once people prune, accumulation dies, and accumulation is the whole product. Idle cells on AgentCell sleep to zero and bill nothing for compute — the twentieth experiment costs nothing to keep. (Also worth knowing: Fly's growth appears to have plateaued — ~$11.2M revenue in 2024 against Render/Railway's $100M 2026 raises. Directional, secondary-sourced, but relevant to "who will still be investing in this in 2028.") ## Gap 2: no identity or sharing layer Fly gives you Machines and networking; who may open the app is entirely your code's problem. Same stitching as everywhere: an auth vendor, a second bill with enterprise floors, session logic duplicated across tools. And stopped Machines wake in multi-second times from cold — acceptable for services, awkward for "click this link in a meeting." ## Side-by-side | | Fly.io | AgentCell | |---|---|---| | Billing | Per-second, auto-suspend; ~$2/mo always-on floor | Per-cell consumption, idle ~zero | | Runtime control | Full — any image, real regions | Curated + org-customizable environments | | Free tier | Removed 2024 | Free idle by design | | Share with colleagues | DIY auth in every app | Share list + identity-aware front door | | Wake from stopped | Multi-second | Wake-latency target measured pre-launch | | Best for | Engineers wanting machine-level control | Teams wanting tools without operating machines | ## Fit checklist **Use AgentCell when:** the audience is people with names, not services; idle cost across many tools must be ~zero; nobody wants to think about Machines. **Stay on Fly when:** you need region placement, custom networking, or exotic runtimes; per-second billing already fits; auth is handled upstream. ## FAQ **Is AgentCell cheaper than Fly for one busy app?** Not necessarily — a single always-warm service may cost the same or less on Fly. The savings appear across *many idle* apps, which is the workload we're built for. **Do you offer Fly-like region control?** Data residency is a region choice in our design, not a thesis. Fine-grained region placement per cell is not a launch feature. --- *Running twenty Fly apps that mostly idle? [Deploy now](/docs/deploy/).* --- # AgentCell vs Heroku for Internal Tools > Heroku killed free in 2022, Eco starts at $5/mo per app, and Salesforce has it in maintenance mode. Twenty idle internal tools means twenty per-app fees — the tax that kills sprawl. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-heroku Markdown: https://agentcell.dev/resources/vs-heroku.md > **TL;DR verdict:** Use Heroku when buildpacks, add-ons, and a decade of operational knowledge still serve a stable app. Use AgentCell when the workload is many occasionally-used internal tools: Heroku's per-app fees ($5/mo Eco and up) charge rent on every tool whether anyone opens it or not. ## Where Heroku wins (honestly) - **Buildpacks.** `git push` and it builds — the workflow every PaaS since has imitated, still smooth. - **Add-ons.** Postgres, Redis, logging, monitoring: one marketplace, attached in a command. - **Known quantity.** A decade of runbooks, Stack Overflow answers, and teams that can operate it blindfolded. Nobody should migrate a stable, working Heroku app on principle. This page is about where the *next* twenty tools go. ## The per-app tax Heroku killed its free tier in November 2022. Eco starts at **$5/mo per app** — and that is the floor, before databases, before anything beyond one tiny dyno. Twenty internal tools, seventeen of them asleep, still cost twenty app-fees. That arithmetic is precisely what makes teams prune: every experiment carries rent, so experiments stop. Add Salesforce's "sustaining engineering" (maintenance) status as of February 2026, and the platform is charging growing rent on a shrinking roadmap. AgentCell inverts the unit: unlimited cells, no per-app fee, idle cells bill nothing for compute. The twentieth experiment costs nothing to keep. ## The missing half (same as everywhere) Heroku is auth-agnostic: the app is public unless your code says otherwise. Internal tools need the same second vendor and second bill (WorkOS/Clerk/Auth0 with their $125–300/mo enterprise floors), plus session logic maintained across every tool. Heroku's add-on ecosystem never included "let three colleagues log in with Google" — because that was never a Heroku-shaped problem. ## Side-by-side | | Heroku | AgentCell | |---|---|---| | Deploy flow | `git push`, buildpacks | `agentcell deploy` from a folder, no git required: static sites detected, servers from a Dockerfile | | Cost per idle app | $5+/mo Eco per app | ~Nothing for idle compute | | Twenty idle tools | ~$100+/mo rent | Storage/domains only, capped | | Data | Add-on Postgres/Redis (mature) | Per-cell datastore + object storage (small-tools scope) | | Share with colleagues | DIY auth in every app | Share list + identity-aware front door | | Trajectory | Maintenance mode (Salesforce, Feb 2026) | Independent vendor, small software only | | Best for | Stable existing apps, steady traffic | Many occasional tools, 1–10 users each | ## Fit checklist **Use AgentCell when:** new tools outnumber stable ones; per-app rent exceeds each tool's value; sharing needs named people, not public URLs. **Stay on Heroku when:** the app is stable, trafficked, and paid for; buildpacks/add-ons are load-bearing; the team already operates it well. ## FAQ **Is this another 'Heroku killer' pitch?** No — Heroku's maintenance-mode status does that work itself. We're the home for what gets built *next*, not a re-platforming crusade. **Can agents deploy to AgentCell like git push to Heroku?** Closer: no git repo required. The agent deploys from the working folder via CLI or MCP tool call, in the session where the code was written. --- *Paying rent on apps nobody opens?

A sprint tracker or invoice tool is the wrong shape for that platform, and per-user team pricing says so. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-huggingface-spaces Markdown: https://agentcell.dev/resources/vs-huggingface-spaces.md > **TL;DR verdict:** Use Hugging Face Spaces when the app is an ML demo, dataset viewer, or Gradio/Streamlit model showcase — nothing beats its model-adjacent ecosystem. Use AgentCell when the tool is *not* ML: ops dashboards, trackers, reconcilers, prototypes — where GPU metering and $20/user team pricing charge ML-platform rent on a 3-user CRUD app. ## Where Spaces wins (honestly) - **Model gravity.** One click from a model repo to a live demo; Gradio and Streamlit first-class; a $13.5B-valued ecosystem (Sept 2025) of datasets, models, and an audience that actually clicks. - **Honest cheap entry.** Pro at ~$9/mo for real hobby scope. - **Community distribution.** Public Spaces get discovered. Internal tools don't need discovery — but demos sometimes do. ## The wrong-shape tax - **Team pricing counts users.** Team at ~$20/user/mo plus metered hardware: for a model team sharing GPU demos, sensible. For a finance team sharing an invoice reconciler with three people, it's per-seat billing wearing an ML costume — the same structural break as Retool, Airtable, and Power Apps (see [vs Retool](/resources/vs-retool/)). - **Hardware metering for software problems.** CPU/GPU-hour meters make sense when inference is the cost. When the cost is "colleague opens a dashboard twice a week," metered accelerators are noise — per-cell vCPU-seconds with free idle matches the workload instead. - **No org-sharing story.** Spaces permissions are repo-shaped (users, orgs, roles for *model artifacts*), not "share this tool with design@, revoke Priya, log who opened it." The front-door pattern (identity-aware proxy, share lists, access logs) doesn't exist there because it was never the product. ## Side-by-side | | Hugging Face Spaces | AgentCell | |---|---|---| | Sweet spot | ML demos, dataset apps, model showcases | Bespoke team tools, 1–10 users | | Team billing | ~$20/user + metered hardware | Per-cell consumption, never per-seat | | Idle demos | Hardware meters keep running | Sleep to zero, ~nothing idle | | Share with named colleagues | Repo-shaped permissions | Per-cell share list + verified identity | | Best for | Anything with a model behind it | Everything else the team builds | ## Fit checklist **Use AgentCell when:** no model is involved; the audience is named colleagues; per-user fees exceed the tool's value. **Stay on Spaces when:** the app demos a model; the HF ecosystem (datasets, community, inference) is load-bearing; public discoverability matters. **Use both when:** the model demo lives on Spaces; the twenty operational tools around the team live on AgentCell. ## FAQ **Can AgentCell serve ML models?** Small-tools scope: light inference inside a tool is fine; serving foundation models is not the product. Keep model demos where the models live. **We're a data team — isn't Spaces our natural home?** For model artifacts, yes. For the sprint tracker, the metric dashboard, and the hiring pipeline tool the data team also maintains — those are small software, and they're the workload Spaces prices worst. --- *ML demos on Spaces, everything else somewhere sane?

So 'no per-seat pricing' alone isn't a wedge. The gap is what happens after the build: SSO floors, opaque credit pools, and builder lock-in. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-lovable Markdown: https://agentcell.dev/resources/vs-lovable.md > **TL;DR verdict:** Use Lovable, Bolt, or Create to *create* apps at remarkable speed — Lovable's $500M ARR and 100k+ new projects/day prove the demand is real. Use AgentCell to *host and share* the ones your team keeps: neutral hosting for any builder's output, per-cell consumption billing instead of an opaque credit pool, and org identity that doesn't start at a $50/mo Business tier. ## Where Lovable wins (honestly) - **Demand, proven.** ~$500M ARR by mid-2026, $6.6B valuation, ~8M users, 100k+ new projects/day. The fastest validation of "people want purpose-built software" in history. - **Non-seat pricing, already.** Workspaces support unlimited members on all plans; plans are priced by included credits, not seats. Create.xyz matches it. This matters because it means "we don't charge per seat" is **table stakes, not a differentiator** — anyone claiming otherwise hasn't read the pricing pages. - **Velocity for non-technical builders.** A reported ~80% of builders are non-technical (vendor claim — treat as directional). The build experience is the product, and it is excellent. Bolt.new (~$40M ARR within months of launch) and the rest of the segment tell the same story: creation is solved and spectacular. The question is where the created things live for the next two years. ## The three gaps after the build ### 1. SSO still starts at $50/mo Lovable is the *most generous* vendor in the research set — and SSO plus the security center still sit at the **$50/mo Business tier**. For one 3-person ops dashboard that will never need SCIM or audit exports, that is a $600/year login form. Replit and Vercel gate SSO at Enterprise; the floor differs, the shape is identical. Nobody sells "invite my ops colleague like a spreadsheet" cheaply. That narrower gap — org identity at the *bottom* of the pricing page — is the actual wedge. ### 2. One opaque credit pool Build credits, hosting credits, AI credits, rollover rules, token-vs-dollar accounting — nearly every builder stacks them. For a non-technical buyer holding a team card, predicting next month's bill requires understanding the vendor's cost model. AgentCell's answer is deliberately boring: per-cell consumption (vCPU-seconds + requests), idle cells bill nothing for compute. ### 3. Builder lock-in vs independence Google is sunsetting Firebase Studio (new workspaces disabled June 2026, full shutdown March 2027). Superblocks exited internal tools via acquisition. Airtable acquihired Airplane.dev in January 2024 and killed it by March. A platform discontinues a builder product the moment it stops fitting the roadmap; **a company whose only business is small software will not.** For a team betting twenty internal tools on a vendor, independence is a purchasing argument — and a neutral host that accepts any builder's output is insurance. ## Side-by-side | | Lovable / Bolt / Create | AgentCell | |---|---|---| | Create apps from prompts | Core product, best in class | Not built — we host what builders output | | Members per workspace | Unlimited (all plans) | Unlimited by design — sharing is per cell | | Billing | Credit pools (build + hosting + AI) | Per-cell consumption, idle = ~zero | | SSO / org identity | Business tier ($50/mo) or higher | Bottom-of-page design goal | | Lock-in | Builder + host bundled | Neutral host for any folder | | Best for | Going from idea to app in an afternoon | Keeping 20 team apps alive for years | ## Fit checklist **Use AgentCell when:** the app is built and the team needs a permanent, shareable, cheap-to-idle home; SSO must not cost more than the app; you want builder independence. **Stay on the builder when:** you are still iterating daily and the integrated loop pays for itself; the credit burn is understood and acceptable; SSO tiers already fit the budget. **Use both when:** build in Lovable/Bolt/v0, deploy the keepers to AgentCell — the designed funnel. ## FAQ **Do I have to rebuild my Lovable app for AgentCell?** No. Export the folder, `agentcell deploy`, re-share the link. A Lovable project is a Vite + React frontend, which AgentCell builds and serves as a static site today. Node or Python server apps need a `Dockerfile` until server detection ships. **Bolt Teams tokens are per-member — does that matter?** It illustrates the point: Teams plans at ~$30/member with non-pooled tokens reintroduce per-head arithmetic through the back door. Per-cell consumption has no headcount in it at all. **What if my builder adds cheap SSO later?** Then one gap closes and the others (opaque credits, lock-in, per-app idle cost) remain. The bet is the combination, and independence still holds. --- *Built five apps this month and need them to survive the year? [Deploy now](/docs/deploy/).* --- # AgentCell vs Railway for Internal Tools > Railway is the friendliest simple PaaS — $5 Hobby, $20 Pro, pure usage, no seats. It also has no access layer at all: you get a public URL and own auth yourself. That's the gap. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-railway Markdown: https://agentcell.dev/resources/vs-railway.md > **TL;DR verdict:** Use Railway when you want the simplest possible deploy-to-URL for apps whose audience is "the internet" or a team that already handles auth elsewhere. Use AgentCell when the app needs *people* attached to it — named colleagues signing in with work accounts, per-app sharing, and idle costs near zero across twenty tools. ## Where Railway wins (honestly) - **Simplicity.** Hobby at $5/mo, Pro at $20/mo, pure usage-based billing with **no seats** — the least hostile pricing in the PaaS set for small teams. - **Momentum.** A $100M Series B in January 2026, 2M+ users, roughly 200k new developers a month. This is the PaaS the AI-built-apps boom is landing on. - **No seat arithmetic.** Railway already rejected per-seat pricing, which puts it closer to our economics than Vercel or Retool. If your small app is already behind your company's VPN or handles its own auth fine, Railway is an excellent, honest host. This page is about the apps where that isn't true. ## The gap: no access layer at all Railway hands you a public URL and treats auth as your problem — completely. There is no built-in access control layer for non-technical colleagues: no "share with Priya," no group lists, no org login, no per-app revocation. So a three-person team does what every PaaS forces: 1. Deploy on Railway (compute bill #1). 2. Pick WorkOS, Clerk, or Auth0, wire OAuth into the app, model users and sessions (identity bill #2 — and recall the auth cliff: WorkOS SSO at $125/mo per connection, Clerk Business at $300/mo flat, Auth0 B2B at $150/mo for 500 MAU). 3. Maintain that auth code in all twenty tools, forever. Two vendors, two bills, two failure modes — for "deploy it and let my colleague log in." The research finding is structural: **every PaaS is auth-agnostic and every auth vendor is hosting-agnostic.** Railway is the cleanest example because it is otherwise the closest to our shape. ## Side-by-side | | Railway | AgentCell | |---|---|---| | Deploy simplicity | Excellent — folder to URL | Same goal: `agentcell deploy`, runtime auto-detected | | Billing | Usage-based, no seats ($5/$20 floors) | Per-cell consumption, never per-seat/app | | Idle apps | Usage floors apply | Sleep to zero, ~nothing for idle compute | | Share with colleagues | Public URL; auth is DIY | Built-in share list + identity-aware front door | | Org SSO for 3 people | Stitch an auth vendor ($125–300/mo cliffs) | Team-tier design goal | | Best for | Public or self-authed services | Tools shared with named people | ## Honest note Railway's positioning as AI-native infrastructure is real, and "no seats" means one of our three differentiators is already matched there. The bet remains the combination: Railway-like deploy simplicity *plus* free idle *plus* cheap org identity. If Railway ever ships per-app identity-aware sharing at the bottom of its pricing page, that combination closes — which is why cheap org identity is the race to win first. ## Fit checklist **Use AgentCell when:** each tool has a different tiny audience; SSO must not cost more than the app; twenty idle tools must cost ~nothing. **Stay on Railway when:** the app is public, behind an existing auth layer, or consumed by services rather than people; usage floors already fit the budget. ## FAQ **Can I keep my Railway apps and add sharing?** The sharing boundary has to sit in front of the app — it can't be bolted on from outside without an identity proxy. Migrating the folder (`agentcell deploy`, re-share) is the designed path. **Does AgentCell do what Railway plugins/databases do?** Per-cell datastore plus object storage cover the small-tools case (trackers, dashboards). Large managed-data estates stay where they are. --- *Have a Railway app that needs a login form? [Deploy now](/docs/deploy/).* --- # AgentCell vs Render for Small Apps > Render's free tier sleeps at 15 minutes with 30–60 second cold starts — the exact failure mode our wake-latency work targets. Same deploy-plus-public-URL shape, same missing identity layer. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-render Markdown: https://agentcell.dev/resources/vs-render.md > **TL;DR verdict:** Use Render when you want managed simplicity (including managed Postgres) for services with steady traffic. Use AgentCell when your tools are used once a day or once a month — where 30–60s cold starts punish colleagues and per-app tier steps punish sprawl. ## Where Render wins (honestly) - **Scale and trust.** $100M raised at a $1.5B valuation in February 2026, explicitly citing the "AI-built apps boom." 4.5M+ developers. This is funded, awake infrastructure. - **Managed data.** Managed Postgres and Redis without operating them — the most common reason small teams pick Render and stay. - **Seat-free tiers.** Starter at $7/mo through Pro at $85/mo: step pricing, but no per-seat counting. For a service with real steady traffic and a database, Render is a fine default. The argument here is about the other shape: occasionally-opened tools shared with three people. ## Gap 1: the cold-start failure mode Render's free web services sleep after 15 minutes of inactivity, and waking takes **30–60 seconds** — widely complained about, and the exact experience that teaches colleagues "don't click that link." Sleep-to-zero only works if waking is fast enough that nobody notices. Our acceptable p95 wake target is set by measurement before launch (not promised in advance), with "always warm" as a likely paid option for tools where the first click must be instant. See [scale-to-zero economics](/resources/scale-to-zero-economics/) for the full tradeoff. ## Gap 2: tiers per app, no identity Each always-on service steps through Render's tiers individually — twenty rarely-used tools means twenty tier decisions. And like every PaaS, Render is auth-agnostic: the URL is public, and "only the ops team can open it" is a second vendor (WorkOS/Clerk/Auth0), a second bill, and auth code in every app. The combined shape — per-app hosting steps plus an enterprise-floored identity bill — is what kills tool #20. ## Side-by-side | | Render | AgentCell | |---|---|---| | Free/idle story | Sleeps at 15 min, 30–60s wake | Sleeps to zero; wake-latency target measured pre-launch | | Always-on cost | Per-service tiers ($7→$85) | Per-cell consumption, idle ~zero | | Managed Postgres/Redis | Yes, core strength | Per-cell datastore for small-tools state | | Share with colleagues | Public URL; auth is DIY | Share list + identity-aware front door | | Best for | Steady-traffic services with managed data | Occasionally-opened tools, 1–10 users | ## Fit checklist **Use AgentCell when:** tools sleep most of the day; each has a different audience; cold starts must not embarrass the link-sharer. **Stay on Render when:** traffic is steady enough that sleep rarely triggers; managed Postgres/Redis is load-bearing; the audience is public or self-authed. **Use both when:** Render hosts the steady services and datastores; AgentCell hosts the twenty occasional tools around them. ## FAQ **Will AgentCell have managed Postgres?** Per-cell datastores (SQLite-shaped or managed Postgres) plus object storage are the design scope — sized for tools that track things, not for production data estates. **What wake latency should I expect?** A measured p95 published before launch, not a marketing number. The Render 30–60s band is the failure mode we're designing against. --- *Got a Render app nobody clicks because waking takes a minute? [Deploy now](/docs/deploy/).* --- # AgentCell vs Replit for Team Tools > Replit owns 'agent builds and hosts' with 50M+ registered users — but collaborator caps, Enterprise-only SSO, and stacked credit metering make it a creator platform, not a home for twenty tiny team tools. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-replit Markdown: https://agentcell.dev/resources/vs-replit.md > **TL;DR verdict:** Use Replit when the agent build loop itself is the product — integrated editor, instant fork, huge community. Use AgentCell when the app is already written (by Claude Code, Cursor, Codex, or Replit itself) and needs a cheap, always-addressable home with per-app sharing that doesn't count collaborators or gate SSO behind Enterprise. ## Where Replit wins (honestly) - **Distribution.** 50M+ registered users, a $9B valuation on a $400M Series D (Mar 2026), ~$150M ARR targeting a $1B run-rate. Replit is the default place "agent wrote an app" happens. - **The loop.** Build, run, iterate, and host in one surface — no export step. For creating, that integration is genuinely good. - **Non-engineer reach.** An estimated 50–58% of business signups are non-engineers. That is our audience too, and Replit found them first. Our stance is explicit: Claude Code, Cursor, Codex, Replit, Lovable are the **top of our funnel, not our competition**. The agent performs the deploy inside a coding session; adoption happens there, not through a signup funnel. Replit-built apps are welcome on AgentCell — export the folder, `agentcell deploy`, done. ## The three gaps for team small software ### 1. Collaboration is counted Replit Core includes 5 collaborators; Pro raises it to 15 collaborators plus 50 viewers. That counting makes sense for a creator product. It breaks for a team with twenty tools, each shared with a different three colleagues — every share is metered against a collaborator budget, and the twentieth tool restarts the negotiation. AgentCell's share list is per cell and uncounted: private → people → groups → org → public link. Sharing tool #20 costs the same as sharing tool #1: nothing beyond its compute. ### 2. SSO is Enterprise-only Same cliff as everywhere else: SSO/SAML lives on the Enterprise tier. A team that wants its ops dashboard behind Google Workspace login pays the enterprise motion for a 4-person audience. ### 3. Metering stacks four ways Replit blends subscription with credit overage across compute, LLM usage, and egress — plus collaborator tiers and rollover rules. Each meter is defensible alone; together they are hostile to exactly the non-technical, budget-conscious buyer the segment claims to serve. A flat, boring, predictable per-cell consumption price is a differentiator nobody currently offers. ## The caution in Replit's own numbers Two figures should discipline the whole category: - Roughly **150,000 paying users out of 30M+ registered (~0.4% conversion).** - Roughly **100,000 of 2M+ agent-built apps in production use (~5%).** Volume is enormous; sustained, shared, paid usage is unproven. Monetising the permanently-small user is the open question for everyone here — including us. Our working hypothesis: consumption is the on-ramp and the floor; the org plan (SSO, groups, access logs, custom environments) carries revenue. If teams won't pay a flat org fee for identity and environment, this is a small business, and no metering fixes that. ## Side-by-side | | Replit | AgentCell | |---|---|---| | Agent build loop | Best-in-class, integrated | Not built — we ride Claude/Cursor/Codex/Replit output | | Host what any agent wrote | Replit-first | Any folder: static sites and frontend builds detected; servers (FastAPI/Flask/Streamlit, Next/Express) with a Dockerfile | | Billing | Subscription + credit overage (compute, LLM, egress) | Per-cell consumption (vCPU + requests), no seats | | Sharing model | Collaborator/viewer counts per tier | Per-cell share list, uncounted | | Org SSO/SAML | Enterprise-only | Team-tier design goal | | Best for | Creating apps with an agent | Hosting and sharing apps agents created | ## Fit checklist **Use AgentCell when:** the app exists and needs a home; sharing is per-tool with different people each time; idle cost across many tools must be ~zero. **Stay on Replit when:** the build-and-iterate loop in one surface is the workflow; community/fork distribution matters; the app's audience fits the collaborator tiers. **Use both when:** build in Replit, host the long-lived team copy on AgentCell. ## FAQ **Can I move a Replit-built app to AgentCell?** That is a designed path: export the folder, deploy, re-share. No rebuild. Static sites and frontend builds are detected today; a server app needs a `Dockerfile` until server detection ships. **Do you compete with Replit's agent?** No. We do not build a code generator; agents already do that well. We are the layer *after* the agent writes the code. **What about usage limits?** Idle cells sleep and bill nothing for compute. Active cells meter vCPU-seconds and requests. Storage, custom domains, and warm capacity are the costs that survive sleep and will be priced or capped explicitly — see [scale-to-zero economics](/resources/scale-to-zero-economics/). --- *Have a Replit app your team actually uses? [Deploy now](/docs/deploy/) and give it a permanent, shareable home.* --- # AgentCell vs Retool for Agent-Built Internal Tools > Retool bundles hosting and identity — then charges per seat ($50–65/builder on Business) for audiences of three. For twenty tiny tools with different users each, per-seat pricing is structurally backwards. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-retool Markdown: https://agentcell.dev/resources/vs-retool.md > **TL;DR verdict:** Use Retool when the job is CRUD-over-SQL with drag-and-drop components and strict governance today. Use AgentCell when the tools are arbitrary agent-written code, each with a different handful of users — where per-seat/per-editor billing charges the full platform fee against a 3-user audience, twenty times over. ## Where Retool wins (honestly) - **Components and bindings.** Tables, forms, queries against real databases — assembled in hours by someone who never wants to see a bundler. Nothing about AgentCell replaces that workflow. - **Governance story.** SSO, audit, and permissions at the Business tier exist *now*, proven in real IT reviews. - **Ecosystem.** Templates, integrations, and a decade of "how do I…" answers. The same holds for the segment: Airtable's grid-plus-automations, Power Apps' Microsoft-graph depth, Appsmith/Budibase/ToolJet's open-source self-host path. These are serious products. The argument here is narrow and structural: **per-seat pricing breaks when the app has three users.** ## Where per-seat breaks: the dollar math | Product | Entry price | The cliff for a 3-user tool | |---|---|---| | Retool | Team ~$10/builder/mo | **Business $50–65/builder/mo** — where SSO/governance gates. 2 builders = $100–130/mo before any end-user cost | | Airtable | Team $20/editor/mo, Business $45 | **Every editor billed monthly regardless of activity.** Portal/guest add-ons $120–150/mo for 15 guests | | Power Apps | Premium $20/user/mo | Cheaper **$5/user/app plan retired Jan 2026**. Pay-as-you-go (~$10/user/app) can cost *more* for teams using several small apps | | Notion | Plus $10/seat | Agents need Business ($20/seat) **plus** $10/1,000 metered credits — seat tax stacked on usage tax | Read the shape, not just the numbers: the cost scales with *users* while the value scales with… also users. There is no leverage. A 3-user tool cannot carry a $50/seat platform fee, so it never gets built there — and the fiftieth small tool, the one with two users, definitely never gets built there. Self-host variants (Appsmith/Budibase/ToolJet) dodge the fee and hand the team a server, backups, and patching — the exact ops tax the thesis targets. AgentCell inverts it: **price per cell compute, never per seat.** A tool opened twice a week costs roughly twice-a-week compute. Idle tools sleep and bill nothing. ## The second gap: components vs arbitrary code Retool's ceiling is its component model — superb inside it, a wall outside it. Agent-written apps don't respect that wall: a FastAPI reconciler with a custom React front end, a Streamlit explorer with private packages, a prototype with three frameworks duct-taped together. AgentCell hosts arbitrary code the agent wrote; the platform provides the environment, the front door, and the safety boundary rather than the widget set. ## Side-by-side | | Retool (+ segment) | AgentCell | |---|---|---| | Build paradigm | Components/bindings | Any code your agent wrote | | Billing | Per-seat / per-editor | Per-cell consumption, idle ~zero | | SSO/governance | Business-tier gate ($100+/mo minimums) | Team-tier design goal, access log per cell | | Share with 3 people, no redeploy | Seat/provisioning ceremony | Google-Doc share list per cell | | Self-host escape hatch | You own the server | No self-host at launch (documented later, if at all) | | Best for | CRUD-over-SQL, governed, component-shaped | Bespoke tools, 1–10 users, agent-built | ## Honest note: category warnings apply to us too Consolidation says the standalone internal-tools category is hard: Superblocks pivoted out and was acquired; Airplane.dev — well funded, technically differentiated — was acquihired and killed within two months. And per-seat incumbents have the enterprise trust we must earn one access log at a time. Our answer: the SSO/deprovisioning story and per-cell access logs are aimed exactly at converting IT's "no shadow tools" objection — but it will cost sales cycles. ## Fit checklist **Use AgentCell when:** tools are bespoke and agent-built; each has a different tiny audience; per-seat fees exceed the tool's value; sprawl of 10–20 tools must cost ~nothing at rest. **Stay on Retool when:** the work is CRUD-over-SQL inside the component model; governance certification is needed this quarter; builders prefer no-code assembly to agent-written code. ## FAQ **Can AgentCell do what Retool components do?** Different mechanism: your agent builds the UI it wants; we provide deploy, identity, and safety. If drag-and-drop assembly is the workflow, Retool remains better at it. **How does IT get comfortable?** Per-cell access log (who opened what, when), org SSO with SCIM-shaped deprovisioning (a leaver loses all twenty tools at once), egress rules and spend caps per cell. That package is the enterprise unlock. **What does one 3-user tool cost?** No final pricing is published yet. The model: pay consumed vCPU-seconds + requests; idle bills nothing for compute.

[Deploy now](/docs/deploy/).* --- # AgentCell vs Streamlit Community Cloud for Team Data Tools > Streamlit Cloud is free but capped at exactly one private app ever, 1GB RAM, 12-hour sleep. A team's home for ten Python tools needs more than one slot. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-streamlit Markdown: https://agentcell.dev/resources/vs-streamlit.md > **TL;DR verdict:** Use Streamlit Community Cloud for your one free public demo or your single private app. Use AgentCell when the team has five or ten Python tools — FastAPI reconcilers, Streamlit explorers, ops dashboards — each shared with a different three colleagues. ## Where Streamlit wins (honestly) - **Zero-config Python.** Push a script, get a data app. Nothing in our plan changes the fact that Streamlit invented this workflow. - **Free.** Genuinely free for public apps — Snowflake-owned, not monetized, no credit arithmetic. - **Community.** The gallery, the forum, the "how do I…" answers for every widget. ## The one-private-app cliff The free tier's terms are precise: **exactly one private app, ever. 1GB RAM. 12-hour idle sleep.** That is not a funnel — it is a ceiling. Your second private tool, your fifth, your tenth: there is nowhere for them to go on this platform. Teams respond by making internal tools public (don't), by sharing one login (don't), or by leaving tools on laptops (the status quo we're all trying to kill). This cap is also a revealed preference: Streamlit, PythonAnywhere, Heroku, and Fly have all shrunk or killed free tiers for permanently-tiny apps. The industry is moving *away* from serving the permanently small — which is why our model starts from "unlimited cells, free idle" rather than bolting it on. ## How AgentCell handles Python cells (stated plainly) A large share of agent-built small software is Python — Streamlit, FastAPI — and the cheapest serving tiers (Workers, Deno) are JS/WASM-only. Resolving near-zero-idle Python is a design problem we measure before launch, not a footnote: per-cell sleep cost and wake latency for Python cells specifically, published before any pricing. What we commit to is the shape: runtime auto-detection from the folder, a per-cell datastore so tracking tools work, a share list instead of "one private slot," and colleagues signing in with work accounts instead of a shared password. ## Side-by-side | | Streamlit Community Cloud | AgentCell | |---|---|---| | Private apps | Exactly one, ever | Unlimited cells | | RAM / sleep | 1GB, 12-hour sleep | Sized per cell; sleep-to-zero design | | Frameworks | Streamlit (Python) | Streamlit, FastAPI/Flask, Node, static | | Share with 3 colleagues | Not beyond the one slot | Per-cell share list, no auth code | | Data | External only | Per-cell datastore + object storage | | Best for | One public demo, one private tool | A team's whole shelf of Python tools | ## Fit checklist **Use AgentCell when:** private tool #2 exists or is imaginable; different tools have different audiences; the team wants work-login sharing, not link-with-password. **Stay on Streamlit Cloud when:** one public demo or a single private app covers the need; free-forever for that shape beats every alternative. ## FAQ **Can I deploy my existing streamlit app.py unchanged?** That is the design goal: folder in, runtime detected, URL out. Streamlit is explicitly in the v1 detection list. Today it needs a `Dockerfile`; the samples repository has a Streamlit app with one. **What about heavy compute (large dataframes, ML inference)?** Small-tools state and interaction, yes. Sustained heavy compute belongs on specialized infra — the always-on fallback tier exists for runtimes that need it, priced accordingly. --- *Got more private Streamlit apps than Streamlit allows?

But per-seat pricing, a $150/mo protection add-on, and Enterprise-only SSO make it the wrong shape for a 3-person internal tool. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/vs-vercel Markdown: https://agentcell.dev/resources/vs-vercel.md > **TL;DR verdict:** Use Vercel for production web apps that serve the public and need to scale. Use AgentCell for tools with three users — where Vercel's per-seat pricing, $150/mo Advanced Deployment Protection add-on, and Enterprise-gated SSO turn a tiny internal tool into an enterprise purchase. The deploy feel is intentionally similar; the sharing and pricing are opposite ends. ## Where Vercel wins (honestly) Credit where it is due — Vercel is the closest competitor and already moving into this space: - **30% of apps deployed on Vercel are now agent-generated** (2026), with a shipped Agent Stack. Nobody else in hosting has this much agent traffic. - **Its MCP server is real.** It deploys from files without a git repo or CLI, streams build and runtime logs, does env-var CRUD, manages domains, and handles promote/rollback over OAuth — with documented Claude Code setup. Any claim that "agent-native deploy" is an empty space is false, and we don't make it. - Frontend scale, previews, and ecosystem are best in class. For a public marketing site or a scaling consumer app, this page is not trying to talk you out of Vercel. Our bet was never a single feature. It is the **combination**: agent-native operation, *plus* unlimited apps with free idle, *plus* cheap org identity in front of every app. Vercel has the first and structural reasons not to offer the other two. ## The three gaps for a 3-person tool ### 1. Per-seat math Vercel Pro is **$20 per user per month**. For a production team shipping a public app, that is trivially worth it. For an internal expense-reviewer used by three people, the seat count *is* the entire audience — you are paying per unit of value with no leverage. Now multiply by twenty small tools, each with a different three users. The arithmetic kills the sprawl before it starts. AgentCell never charges per seat and never per app: unlimited cells, metered on consumed vCPU-time and requests. The twentieth rarely-used tool is free to keep alive. ### 2. Sharing costs $150/mo extra Want colleagues to open an internal deployment without the public internet seeing it? That is **Advanced Deployment Protection — a $150/mo add-on on Pro**, free only on Enterprise. Vercel's "Shareable Links" (a query-string token for external viewers) is the closest existing pattern to per-app sharing and worth studying — but it is a token on a deployment, not a Google-Doc share list with people, groups, org-wide access, and revocation. On AgentCell, the share list is the product: private → specific people → groups → anyone in the org → public link, per cell, changeable without a redeploy. ### 3. The Hobby trap and the SSO gate Vercel Hobby is free but **explicitly non-commercial** — an internal company tool on Hobby is technically a licence violation, an odd trap for team tools. And **SAML SSO plus SCIM are Enterprise-only**. A 5-person team wanting Google SSO for its sprint tracker is quoted the same enterprise motion as a 5,000-person company. Our position: org-scoped identity and sharing belong at the *bottom* of the pricing page, not the top. That is the wedge. ## Side-by-side | | Vercel | AgentCell | |---|---|---| | Deploy from agent (MCP/CLI) | Yes — mature MCP server | Yes — MCP + CLI, the primary interface | | Billing | Per-seat ($20/user) + usage | Per-cell consumption, never per-seat/app | | Idle apps | Billed tiers / usage floors | Sleep to zero, pay nothing for idle compute | | Share with 3 colleagues privately | $150/mo protection add-on (Pro) | Built-in share list, no redeploy | | Org SSO (SAML/SCIM) | Enterprise-only | Core team-tier feature (design goal) | | Hobby/free for company tools | Non-commercial licence trap | Free idle by design | | Best for | Public production web apps | Tools with 1–10 users | *Pricing as of mid-2026 from public pages; verify before relying on it.* ## Honest note: what we'd be foolish to claim Vercel's MCP server already covers deploy, logs, env vars, domains, and rollback. Fly already bills per second with auto-suspend. "Agent-driven operation" and "scale to zero" are each one product decision away for a better-funded company. Neither is defensible alone. The bet is that Vercel cannot abandon per-seat pricing or make the dashboard optional without breaking its own business — and that the combination stays unassembled there. ## Fit checklist **Use AgentCell when:** the audience is 1–10 people; you want `deploy` then a share link, with no seat arithmetic; idle cost must be ~zero across many tools. **Stay on Vercel when:** the app is public-facing and must scale; you need its frontend ecosystem and preview workflows; you already pay for Enterprise SSO and protection. **Use both when:** Vercel serves the public app; AgentCell hosts the twenty internal tools around it. ## FAQ **Can I deploy the same repo to both?** Yes. A static or frontend project (Vite, Create React App, Vue, Svelte, Astro, Next.js with `output: 'export'`) is detected from its `package.json` `build` script and served as a static site. A server, including Next.js in server mode, needs a `Dockerfile` today; detecting servers is planned. Nothing Vercel-specific needs rewriting for typical small apps. **Does AgentCell do preview deployments?** Per-cell rollback and redeploy are core; Vercel-style per-commit preview URLs for large teams are not the focus. Small tools have one environment: the shared one. **What about cold starts?** Sleep-to-zero trades wake latency for cost. Render's free tier (15-min sleep, 30–60s cold starts) is the failure mode to avoid; our acceptable p95 wake target is set by measurement before launch, with "always warm" as a likely paid option. See [scale-to-zero economics](/resources/scale-to-zero-economics/). --- *Built something useful for three? [Deploy now](/docs/deploy/) and bring the tool stuck on localhost.* --- # What Is Small Software? > Small software is purpose-built tools with one user or a handful of users — the invoice reconciler, the sprint tracker shaped like your sprints, the prototype for three colleagues. Agents made it easy to build. Sharing it is the unsolved part. Published: 2026-09-19 Canonical: https://agentcell.dev/resources/what-is-small-software Markdown: https://agentcell.dev/resources/what-is-small-software.md > **TL;DR:** Small software is software with one user or a handful of users, built for a specific team rather than a market. Agents removed the cost of writing it. Everything after the writing — deploying it, letting a colleague log in, keeping twenty of them alive without doing pricing arithmetic — is where it still dies. That gap is what AgentCell exists to fill. ## The definition Small software is a script that reconciles your invoices. A dashboard for the one metric your team actually cares about. A sprint tracker shaped like *your* team's sprints, not Jira's. A prototype you want three colleagues to click through. Three properties define it: 1. **The audience is fixed and tiny.** One person, or a handful. It will never have a thousand users, and that is fine — it was never meant to. 2. **It is bespoke by nature.** Every team does things differently, so demand for tools shaped like the team is effectively unlimited. No vendor can pre-build them all. 3. **It has no operator.** There is no platform team, no on-call rotation, no one whose job is the deploy pipeline. There is one person who wanted a tool, and now an agent that wrote it. That third property is the one the entire cloud industry ignores. AWS, Vercel, Render — all of them assume someone, somewhere, operates the software. For small software, nobody does. The person who wanted the tool is not a cloud engineer and does not want to become one. ## Why now: agents removed the build cost This category did not exist at this scale two years ago because writing even a small app cost real engineering time. That cost is now gone: - Lovable reports 100,000+ new projects per day and roughly $500M ARR (mid-2026). - Replit saw 2M+ apps built by its agent in a six-month window. - Vercel reports 30% of apps deployed on its platform are now AI-agent-generated. - Claude Code went from a $500M run-rate to over $2.5B in about five months. Building personal software with an agent is genuinely easy now — and genuinely fun. The build is autonomous right up to the moment the app has to ship. Then a human has to take over: create a project in a console, click through a deploy wizard, paste env vars into a form, wire up auth so a colleague can log in. The agent is fully capable of doing all of it and is simply not allowed to. So every small app carries a human operator tax larger than the app itself. ## The five failures after the build **1. The dashboard wall.** The build is autonomous until shipping, then it becomes clicks in a console. Logs tabs, rollback buttons, env-var forms — every one of them a translation step between what the agent wants to do and what a human must click. **2. Clouds built for Big Software.** Accounts, IAM, VPCs, load balancers, certificates, CI, secrets, observability, an unpredictable bill. Rational overhead for a system serving a million users; absurd overhead for a tool with three users. Most small software never leaves the machine it was built on. **3. Sharing is an auth problem.** "Send this to Priya on the ops team" means picking an auth provider, wiring OAuth, modelling users and sessions, handling her leaving the company. Same work every time, wildly disproportionate to 200 lines of business logic. **4. Sharing agent-written code is a security problem.** If sharing is as easy as a Google Doc, then untrusted code deployed by a non-engineer runs against company data. That needs real isolation, egress control, and secret handling — enforced by the platform, because the deployer cannot be expected to reason about it. The base rates are bad: roughly 38% of AI-generated code carries at least one security flaw, and CVEs traced to AI-generated code accelerated sharply through 2026. **5. Every company wants its own environment.** Base images, private packages, internal APIs, network boundaries, data residency. A platform with one blessed runtime gets rejected by exactly the teams with the most small-software demand. ## What small software is not - **Not a startup idea.** It has three users and will always have three users. It does not need product-market fit, analytics, or a landing page. - **Not a prototype for big software.** Some small tools grow up, but most are finished at their current size. Judging them by "will it scale" misses the point. - **Not shadow IT to be eliminated.** Gartner puts shadow IT at 30–40% of large-enterprise spend. Much of it is small software solving real problems faster than IT can. The answer is a sanctioned home for it, not a ban. - **Not a notebook or a spreadsheet.** Notebooks and sheets are where small software goes to be quietly hated. They work until they don't — no auth model, no versioning, no ownership story. ## The honest caveats Two numbers should discipline everyone's enthusiasm, ours included: - Replit converts roughly **0.4% of registered users to paid**, and only about **5% of agent-built apps** reached production use. Volume is enormous; sustained, shared, paid usage is unproven. - Val Town — the closest philosophical match to this thesis — is a ~3-person team whose stated 2026 goal is simply break-even. Small software may be mostly personal, mostly unshared, and mostly abandoned. That is the risk our discovery process exists to kill honestly. The metric that matters is not deploys — it is *cells shared with at least one other person*, and weekly active users who did not build the cell. ## Where to go next - [Share it like a Google Doc](/resources/share-like-a-doc/) — how sharing works on AgentCell. - [Unlimited apps; pay only for consumption](/resources/scale-to-zero-economics/) — the economics that let twenty tools stay alive. - [AgentCell vs Vercel](/resources/vs-vercel/) — why Big-Software clouds can't collapse this cost. --- *AgentCell is the cloud for small software: deploy the tool your agent built, share it like a doc.

How it is detected, built and published, and why no microVM runs for it. Published: 2026-09-25 Canonical: https://agentcell.dev/blog/static-sites Markdown: https://agentcell.dev/blog/static-sites.md A lot of what coding agents build has no server. A Vite + React dashboard that reads a CSV, a page of documentation for a team, a small tool that talks to an API from the browser. Until today, deploying one of those to AgentCell meant a Dockerfile that wrapped a web server around a folder of files, and a whole microVM to run it. As of 25 September 2026, `agentcell deploy` doesn't need the Dockerfile for these. Give it a folder of HTML, or a frontend project with a `build` script, and it builds the site on the platform and serves it. No microVM runs for it at all. This post covers what you can deploy, what happens when you do, and what isn't there yet. ## What deploy accepts now `deploy` reads the root of the directory and takes the first of three shapes that matches: | The root holds | What you get | |---|---| | a `Dockerfile` | A container cell, exactly as before: the port from its `EXPOSE` (8080 when there's none) and `/data` for anything that must survive a restart. | | a `package.json` with a `build` script | A static site, built on the platform. `npm ci` when there's a `package-lock.json`, otherwise `npm install`, then `npm run build`. The first of `dist/`, `build/` or `out/` that holds an `index.html` is what gets served. | | an `index.html` | A static site, served as it is, with no build. | The middle row covers Vite, Create React App, Vue, Svelte, Astro, and Next.js with `output: 'export'`. The order matters: a directory with a Dockerfile is still a container, even if it also has a `package.json`. ```sh agentcell deploy --cell team-dashboard . # prints https://team-dashboard.agentcell.cloud agentcell logs --build team-dashboard # the npm output, if the build fails ``` Use client 0.1.4, released today, for frontend projects. It leaves `node_modules` and the frontend build caches out of the upload, since the platform runs the install itself. An older client uploads `node_modules`, and a typical frontend project then goes over the upload limit. ## Why no microVM runs for it Every container cell is a Kata microVM with its own guest kernel. That's the right boundary for code we didn't write, and it costs about 380 MiB of real memory per cell. Container cells don't sleep yet, so that memory is spent whether anyone is using the app or not. A folder of files needs none of it. There's no process to isolate and nothing to keep warm. So a static site never reaches the scheduler: the platform's edge serves its files from object storage. With two static sites live, free memory on the workers moved by at most 4 MB. It's also a smaller attack surface. Once it's built, a static site runs no code of yours anywhere on our machines. The build does run your code, since `npm run build` is a script you wrote, and it runs where every build runs. ## What happens when you deploy one **Detection.** The control plane unpacks the upload and applies the three rules above, in order. A directory that matches none of them is refused, and the error names all three shapes. **The build.** A frontend goes through the same build job as a container, on the same build machines, inside the same kind of sandboxed microVM. The project has no Dockerfile, so the control plane supplies one: install, `npm run build`, then a final stage that keeps only the chosen output folder. Your `npm install` gets no more privilege than anyone's Dockerfile does. The result is an image that holds files and no program. A plain `index.html` site skips this step. **Publishing.** The platform pulls the built image, checks that it carries this deploy's marker, and takes out the files. Anything whose name starts with a dot is left out, except `.well-known/`, so a stray `.env` in the folder is never served. The files go into object storage as one archive, which is read back and checked against its checksum before the cell's name is pointed at it. The site also gets its own Cloudflare Access application, like every cell. **Serving.** A request goes through Cloudflare Access and the tunnel to the edge router, the same path as any cell. The router verifies the sign-in, then serves the file from a local copy of the archive, fetched from storage and checked against the checksum before it's used. ## How paths resolve The rules follow the usual static-host conventions: - `/about` redirects (308) to `/about/` when `about/index.html` exists. Otherwise `about.html` is served. - With no `404.html`, an unknown path with no file extension gets `index.html`. That's what a single-page app with client-side routes needs: `/reports/march` survives a reload. With a `404.html`, that page is served with status 404 instead. - Hashed files under `assets/`, the names a bundler like Vite writes, are cached by browsers as immutable. A redeploy produces new names, so it is picked up on the next load. - An `"agentcell"` key in `package.json`, such as `{"output": "public", "spa": false}`, overrides the output folder and the single-page fallback. Two sample apps show all of this: [`static-plain`](https://github.com/AgentCell-dev/samples/tree/main/static-plain), a folder of HTML with a `404.html` and a committed `.env` canary that must never be served, and [`vite-react`](https://github.com/AgentCell-dev/samples/tree/main/vite-react), a single-page app with a client-side route. ## Same front door, one more check A static site gets the same private `https://.agentcell.cloud` address and the same sign-in as a container cell. The edge router checks the signed identity assertion the same way: signature, pinned algorithm, issuer, expiry. A valid signature proves the assertion came from our Access account, though, not which cell it was issued for. So for static sites the router also checks that the assertion was issued for that specific cell's Access application. We tested it live: another organisation's genuine sign-in, sent to a static site, is refused with a 403 and none of the site's bytes. Web cells don't have this check yet. For them, each cell's own Access application is the only per-cell binding for now. [The isolation post](/blog/tenant-isolation) has the details. Everything in a static site is readable by anyone who can open it. That's true on any host, but worth saying: an API key in a frontend bundle is a published API key. ## What the rollout caught We turned static sites on one switch at a time. The first live smoke test failed 7 of its 88 checks, because Cloudflare was rewriting HTML in flight (email obfuscation) and dropping our ETag. Every static response now carries `Cache-Control: no-transform`, and the rerun passed 90 of 90. [Breaking it on purpose](/blog/breaking-it-on-purpose) has the longer version. ## What isn't there yet - **Servers still need a Dockerfile.** FastAPI, Flask, Streamlit, Express, and Next.js in server mode aren't detected without one. A coding agent writes one in a few seconds, and the [samples](https://github.com/AgentCell-dev/samples) include several to copy. - **Container cells don't sleep.** Scale-to-zero is designed, not shipped. Static sites sidestep it by having no machine of their own. - **No public sites.** Every cell, static or not, is behind sign-in. There's no sign-in-free option yet. - **No custom domains**, and no `env` or `secrets` verbs, so a build can't be handed values from outside its source. - **Rollback is ours, not yours, for now.** We can roll a static site back to an earlier version from the operator side. The public `rollback` verb hasn't shipped. - **At most 10 static sites per organisation**, for now. We'll say so here when these change. --- *For the full deploy path, container and static, read [what happens when you run agentcell deploy](/blog/how-a-deploy-runs).

What each drill proves, what it has caught, and where we are taking resilience next. Published: 2026-09-24 Canonical: https://agentcell.dev/blog/breaking-it-on-purpose Markdown: https://agentcell.dev/blog/breaking-it-on-purpose.md On a platform our size, reliability mostly comes down to knowing what happens when something fails. We find out by making things fail on purpose, on a schedule, and writing down what happened. Below are the drills we run, what each one has caught, and where we are taking resilience next. All the numbers come from our own logs. ## No pets Every machine in the platform can be destroyed and rebuilt from the repository. Nothing gets configured by hand and then remembered. We test that literally: ```bash make rebuild-test # destroy a worker, recreate it, configure it, put it back in service ``` The first full run of this drill did exactly what a drill is for: it surfaced five things to harden, on a quiet afternoon rather than during an incident. The biggest was about first contact. We lock every machine down so it is reachable only over our encrypted overlay network, and a brand-new machine isn't on that network yet. The drill showed that a fresh machine's very first configuration run needed its own way in, so we built one. It also found a readiness check that assumed an existing machine: it waited for the overlay's network interface before the software that creates that interface was installed. Harmless on a running machine, a two-minute stall on a fresh one. It now runs in the right order. The rest were small refinements to the rebuild script itself, such as handling a remembered SSH host key and a machine learning its own overlay address mid-run. The run that followed passed unattended, end to end. We then moved a live app onto the rebuilt machine and it served the same data as before. We repeat the drill monthly, so rebuilding a machine stays a routine operation. ## The second run changes nothing We configure machines with Ansible. A change isn't done until two complete configuration runs across every machine have passed back to back and the second one changed nothing. A second run that still changes something means the configuration only works once, or is fighting itself. Holding every change to this standard catches configuration that works on the first run and not the second, and service restarts that never actually fire. We check it on every change, and run a third time when we want to be sure. ## Your data leaves the machine every five minutes Each app (we call it a cell) gets a `/data` volume. restic backs it up to Cloudflare R2 every five minutes and again whenever the cell stops, and the cell restores from there whenever it starts somewhere new. We deliberately don't keep backups on our own storage, because that storage sits next to the apps and would fail along with them. We test two things. One is that restores actually work. The backup test writes data, backs it up, deletes the original, restores it, checks that it's byte-identical, and then has restic re-read every stored block to verify it. Moving a cell from one worker to another is itself a restore from R2, so every move exercises the same path. The other is how much you can lose. We measured it by writing marker A into a live cell, waiting for it to reach a backup, writing marker B, and then cutting the power to the worker, abruptly, with no clean shutdown. The cell came back on the other worker after 94 seconds, serving marker A. Marker B was gone. So the claim holds: at most, you lose what was written since the last backup, and nothing else. We refined the drill twice until it measured precisely that claim and nothing adjacent to it. We also keep an eye on how quickly a restore can start. At one point a restore's listing step had grown to about 700 seconds, because a stale lock was keeping retention from pruning old snapshots. Retention now runs continuously: the snapshot count went from about 7,000 to 39, and the listing takes about 6 seconds. It was fixed before any cell needed to move in a hurry. Deleting has two levels. `destroy` stops an app and removes its volume but keeps its backups. `purge` deletes the backups too, and can't be undone. ## A safety check that needed context Consul, our service discovery, refuses to let a server rejoin its cluster after more than seven days offline. In a multi-server cluster that's a sensible rule: a long-absent server has a stale view and shouldn't get a vote. We met this rule while bringing the platform back up after a pre-launch pause. Our cluster runs a single server today, so there was no one for it to be stale against, and the check was simply keeping it from starting. The error message suggested wiping the data directory. That would have discarded the service catalogue and the access-control state to satisfy a clock comparison, so we didn't. Nothing was lost. Instead, the setting is relaxed only while there is exactly one server. Add a second server and the configuration drops the override by itself, which restores the safety check at exactly the point where it starts to matter. It's a good reminder that the fix a system suggests isn't automatically the right fix for your situation. ## A canary that signs up every day Unit tests cover the parts. We also wanted something that covers the whole path a new customer takes, so we run a canary that behaves as a real customer, over the public internet, using the public client. Each run: 1. Presents a machine credential to the human login page and expects to be refused. 2. Deploys four sample apps, each of which has to serve the marker from its own build. 3. Has one app write a note to its SQLite database, redeploys it, and checks that the note reads back. 4. Tears everything down: apps, volumes, backups and login applications. It runs daily on a timer, and also after any configuration change. Each check reports a gauge to our metrics, and an alert pages us if a gauge reads zero or if the canary stops reporting altogether. The canary earned its place during commissioning. Each of its first six runs hardened something, and one of them found a product edge case that no unit test could reach: redeploying identical source straight after purging an app. Deploys are idempotent, so the second one was recognised as "unchanged" and pointed at the purged deployment. Removing an app now clears that record too, and the canary exercises the path every day. It has also shown us how the platform behaves when the network is having a bad night. One run coincided with a slow network, and a build that normally takes a minute or two took seven. The canary allows four minutes, so it flagged the delay, which is exactly its job. We kept the threshold where it is. That run also gave us five refinements to make the canary's own reporting sharper. The main one: one slow deploy should be reported as one finding, not four, and teardown should wait for any deploy still in flight before it declares an app gone. ## A smoke test that checks the bytes Static sites went live on 25 September, one switch at a time. The first live run of their smoke test failed 7 of its 88 checks. The sites were up, and in a browser they looked fine. The smoke test doesn't look; it compares what comes back with what was published, and the two differed. Cloudflare was rewriting HTML in flight, through its email obfuscation feature, and dropping the ETag we set. Harmless-sounding, but a tenant's page should be exactly the bytes they deployed, and an ETag that disappears breaks the browser's cache checks. The fix was one header. Every static response now carries `Cache-Control: no-transform`, which tells anything in between not to modify the body. The rerun passed 90 of 90. It's the same lesson as the upload stall in [the deploy post](/blog/how-a-deploy-runs): the problem lived at a boundary, and only a check over the real route, reading the real bytes, could see it. ## Watching the monitors An external probe checks the public path from outside our network. Every machine also has a dead-man alert, which fires when the machine stops reporting, not only when it reports something bad. The dead-man alerts proved themselves within five minutes of going live: they spotted three machines whose metric shipping had stalled, and all three were back to normal within half an hour. Alerts go to Slack. We measured delivery end to end with a test rule that fires on purpose, and the page arrived in 23 seconds. We rehearse the emergency switch too: turning public traffic off took effect in 17 seconds, and turning it back on took 15. ## How changes ship When a change touches both code and the database schema, we decide the order for that change and write it down. For example: update the admission proxy, then the control plane, then apply the schema within seconds. Old code keeps working against the old schema for those few seconds, so deploys carry on throughout. Implementation is split into small packages. Each one is built in its own isolated worktree and reviewed on its own before it merges, one at a time. We also don't count a check until we've seen it fail, and that goes for reliability checks as much as security ones. It's the same principle behind every drill on this page. ## Where we're taking resilience next - **One region today.** A regional outage would take the platform offline until the region recovers. Your data is backed up off-site to R2, so it survives either way. Running in more than one region is a later step. - **A second control-plane server.** The scheduler and service discovery run as single servers. Adding a second is a known, planned step, and the Consul override above already removes itself when it happens. - **An independent database copy.** Database recovery uses our managed Postgres provider's point-in-time recovery today. An independent off-site copy is planned. - **Sharper canary reporting.** The five refinements from the slow-network run are in progress. The external probe and dead-man alerts watch the running system continuously in the meantime. When items come off this list, we'll say so here. --- *This is the last post in a series on how AgentCell is built.

Published: 2026-09-24 Canonical: https://agentcell.dev/blog/how-a-deploy-runs Markdown: https://agentcell.dev/blog/how-a-deploy-runs.md You type one command in a directory that has a Dockerfile, or a frontend project, or just an `index.html`. A few minutes later a colleague opens a URL, signs in with the account they already have, and uses the app. This post walks through what happens in between, for a container and for a static site. It also serves as the map for the other two posts in the series, which go deeper on isolation and reliability. Everything described here runs today. Where we've designed something but haven't built it, we say so, and those items are collected at the end. ## The rule underneath everything Our infrastructure repository starts with one rule: > A service may never address another service by `localhost`, by LAN IP, or through a shared filesystem. Services find each other by name, over an encrypted overlay network (Tailscale), through service discovery (Consul). CI has a lint check that searches for loopback addresses and hard-coded private IPs and fails the build when it finds one. The point is that no machine is special. If nothing depends on where a service happens to run, moving it comes down to a DNS record and a firewall rule, and rebuilding a machine from scratch is routine. The reliability post shows what that gets us when a machine is switched off mid-request. ## The machines The platform is split across separate machines, each with one job: - Control plane: the API, the scheduler's servers, service discovery and the admission proxy. - Build machines, which turn source into images and never run customer apps. - Registry and storage, for built images, uploaded source and published static sites. - Edge, the only machine that talks to Cloudflare and the only way in for a request from outside. It also serves static sites itself. - Workers, a pool of machines that run cells and nothing else. The workers sit on their own network segment, where forwarding is deny-by-default. A cell can move from one worker to another, and its data moves with it. All of these machines are created by Terraform and configured by Ansible from the same repository, so any worker can stand in for any other. ## 1. The client knows two things `agentcell` is a single static Go binary, built only from the standard library. It's both the CLI and an MCP server, so a coding agent deploys with the same code a person uses. All it knows about the platform is a base URL and a token. The token comes from `agentcell login`, which signs you in through a browser on any device, including a phone, and lives in a file under your user's config directory, or can be read from an environment variable. The client never prints it and won't accept it as a command-line argument, since that would put it in your shell history. You don't need Docker installed. The client packs up the source directory and uploads it. Since version 0.1.4 it leaves `node_modules` and frontend build caches behind, because the platform runs the install itself. ## 2. The control plane decides The upload goes to `api.agentcell.cloud`, through Cloudflare, to the control plane. That's a small HTTP service written against Python's standard library, with its state in Postgres (Neon). Before doing any work it runs four checks, in order. The first is who's asking: the token is checked against a salted scrypt hash, and we don't store tokens in any form that could be read back. Then which org the token belongs to. Every operation is scoped to that org, and if you ask about another org's app you get a "not found" that is byte-for-byte identical to the one for an app that doesn't exist. Then whether the token's scope allows the operation. Last is the rate limit, which is applied after authentication so that a stranger can't use up a customer's allowance. Then it looks at the root of the upload and picks the first of three shapes that matches. A `Dockerfile` means a container, which is built in step 3 and placed in step 5. A `package.json` with a `build` script means a frontend to build into a static site. A bare `index.html` means a static site with nothing to build. Anything else is refused, and the error names all three. Each deploy carries an idempotency key derived from the hash of the source. Submit the same bytes twice and the second response is `unchanged`, pointing at the same deployment. In our test the first submission took 76 seconds and the second took 3.4. Agents retry, and we don't want a retry to start a second build. ## 3. The build runs in a sandbox too The source goes into object storage, and a build job is scheduled onto a dedicated build machine. BuildKit builds the image inside a Kata microVM on that machine; the build itself doesn't run on the host. Building an image needs more privilege than running one. That extra privilege exists only on the build machines, which never run customer apps, and if the same build task is forced onto a machine that runs apps, it's refused. Your Dockerfile doesn't need to know anything about us. The platform reads the port from the last `EXPOSE` in the final stage, or uses 8080 and tells you it did. It stamps a marker file into the image and, before deploying, reads that marker back out of the pushed image, so we can prove the image that runs is the one that was built. The image goes to our private registry, which refuses anonymous pushes and pulls. Each worker pulls with its own read-only credential. Builds queue, one at a time per build machine. A build that's waiting is reported as queued, so it doesn't look stuck. A frontend goes through exactly the same build. It has no Dockerfile (detection just established that), so the control plane supplies one: `npm ci` when there's a lockfile, `npm install` when there isn't, then `npm run build`, then a final stage that keeps only the first of `dist/`, `build/` or `out/` holding an `index.html`. Your `npm install` runs on the same build machines, inside the same kind of sandboxed microVM, as anyone's Dockerfile. What comes out is an image with no program in it, only files. ## 4. A static site stops here A static site never reaches the scheduler. The platform pulls the built image, checks its marker the same way, and takes out the files. A plain `index.html` site skips the build and is published straight from the upload. Files and folders whose names start with a dot are left out, except `.well-known/`, so a stray `.env` is never served. The files are packed into one archive in object storage, read back and checked against their checksum, and the cell's name is pointed at that archive. The site gets its own Cloudflare Access application, like every cell. There's no job, no microVM, no network and no `/data`. With two static sites live, free memory on the workers moved by at most 4 MB; a container cell costs about 380 MiB. ## 5. Placement: one template, one door Every app (we call them cells) is rendered from a single job template. Nobody hand-writes a job for a customer or creates a volume by hand, and if we ever find we need to, we'll treat that as a bug. The rendered job goes to Nomad, our scheduler, and the only way to get it there is through an admission proxy. The proxy refuses any job that doesn't run under the Kata runtime or doesn't join the cell's own private network, and it does that before Nomad sees the job. Nomad's API is firewalled from everywhere else, so someone holding a valid credential who skips our client and talks to the scheduler directly still goes through the same checks. What the proxy refuses, and why, is in the isolation post. Nomad places the cell on a worker, where it starts as a Kata Containers microVM: a lightweight virtual machine with its own guest kernel. Your code only ever runs inside one of these, not in a shared-kernel container. Each cell gets its own network, a bridge that no other cell is attached to. From inside it, a cell can't reach its neighbours or any platform service, including the scheduler, service discovery, the registry and storage. It also gets a `/data` volume that survives restarts and redeploys. restic backs it up off the machine to Cloudflare R2 every five minutes and again when the cell stops, and it's restored when the cell starts somewhere else. Moving a cell between workers is, in effect, a restore. And there's a health check on `/`. After three failures in a row, Nomad restarts the cell. `agentcell deploy --schedule` gives you a scheduled cell instead. That's a cron job with no URL that runs to completion, with overlapping runs prohibited. The admission proxy has its own list of refusals for jobs of that shape. ## 6. The request path A request from your colleague's browser takes this path: ```text browser → Cloudflare edge TLS, and Cloudflare Access: who are you? → Cloudflare Tunnel outbound-only from our side; no open inbound port → edge router re-verifies the signed identity; strips credentials → the cell's microVM found by name in service discovery ``` There are no inbound ports. Our edge machine dials out to Cloudflare and requests come back over that connection, so we have no public IP address serving traffic and no open inbound port for anyone to scan. Sign-in happens before your code runs. Each cell has its own Cloudflare Access application listing the people it's shared with, and a stranger gets a login page or a 403 without ever reaching your app. Your app doesn't implement any authentication itself. We don't take the edge's word for it, either. The edge router re-verifies the signed identity assertion on its own: it checks the signature against Access's published keys, pins the algorithm, and checks issuer and expiry. Then it removes cookies, `Authorization` and the assertion before the request reaches the cell, so a cell never holds a credential it could replay somewhere else. A hostname that doesn't exist gets the same answer as one that does, so nobody can enumerate cell names. For a static site the last hop is the edge router itself. After the same verification, it checks one more thing: that the sign-in token was issued for this particular cell. Then it serves the files from a local copy of the archive, fetched from storage and checked against the checksum. Unknown paths with no file extension get `index.html`, so a single-page app's routes survive a reload, unless the site ships a `404.html`. The isolation post covers that per-cell check, including where it doesn't apply yet. ## Why we test over the real route Our end-to-end harness runs every deploy path over the public route as well as the private network. Before our first client release, it caught a pre-release build stalling on upload over the public route, although every test over the private network had passed. A goroutine dump showed the client parked, waiting for the server to say "go ahead". The client had started sending `Expect: 100-continue` so that a refusal would arrive before a large upload. Over HTTP/2, Go strips that header but still holds back the body. Cloudflare waited 15 seconds for a body that never came and reset the stream. Go treats a reset before any body has been sent as safe to retry, so it retried, every 15 seconds, indefinitely. The fix was to send the header only when talking to the private network directly, and a test now fails if the client ever sends it over HTTPS. The fixed build then passed the full harness over the public route, and that is the build we released. Each component was correct on its own; the issue lived only at the boundary between them, which is exactly what the harness is there to exercise. ## What's coming next A few things you might expect aren't there yet: - Container cells don't scale to zero. They don't sleep today, so an idle container cell keeps its memory. It's designed and on the roadmap. A static site has no memory to keep. - A Python or Node server with no Dockerfile isn't detected. Static sites are; servers need a Dockerfile for now. - There's no `agentcell secrets` yet. Please don't work around that by putting credentials in your source. - Outbound traffic has no allowlist. Cells can't reach each other or the platform, but they can reach the public internet. Per-cell allowlists are designed but not enforced yet. - Spend caps and per-cell access logs are both designed, and neither is built. - AgentCell runs in a single region today, with one control plane. If that region has an outage we're down, with no failover. Backups are stored off-site, so an outage wouldn't mean data loss. Each of these has a written design with its own test for "done". We'll say so here when one ships. --- *The rest of the series: [where one tenant ends](/blog/tenant-isolation) and [breaking it on purpose](/blog/breaking-it-on-purpose).

The five layers between one cell and everything else, what each refuses, and how we check that it can fail. Published: 2026-09-24 Canonical: https://agentcell.dev/blog/tenant-isolation Markdown: https://agentcell.dev/blog/tenant-isolation.md Most of the code AgentCell runs was written by an agent in an afternoon, and nobody reviewed it. Some of it will have bugs a stranger could exploit. Some of it may be deliberately hostile: anyone can sign up, and an agent with a shell is a realistic adversary in its own right. So we assume whatever is inside a cell is compromised, and ask what a compromised cell can reach. This post goes through the layers between one cell and everything else, roughly in the order a request or an escape attempt would meet them. For each one we say what it refuses and how we check that it really does. We try to keep what runs today apart from what is only designed. The things that aren't built yet are listed at the end, and if you're evaluating us you may want to skip there first. ## Layer 1: a separate kernel Every cell that runs code runs as a Kata Containers microVM. (A static site runs none: the edge serves its files, and there's no process of yours on our machines to escape from.) It's still a container image, but it boots inside a lightweight virtual machine with its own guest kernel instead of sharing the worker's kernel through namespaces. We measure this rather than take it on faith. An isolation check runs inside a live cell and compares what it sees with the worker around it. The kernel version inside the cell is the guest's, and differs from the worker's. The cell sees three or four processes, where the worker has about a hundred. Files that exist on the worker aren't visible from inside. All of it still holds after the cell is moved to a different worker. The control run is more interesting. Run the same app as an ordinary container, with the `runc` runtime, and the check fails, though only just: the ordinary container passed five of the six checks and failed only on the kernel. A shared-kernel container can hide processes and files from itself quite convincingly. It can't hide the kernel, and the kernel is what an escape goes through. The scheduler configuration enforces the runtime. Kata is the only runtime permitted and also the default, so leaving the runtime unset doesn't fall back to something weaker, and the ordinary runtime has been removed from workers entirely. Privileged containers and host volumes aren't allowed. Building an image needs more privilege than running one, so builds get it only on separate build machines that never run customer apps, and the build itself runs inside a microVM as well. That includes the `npm install` and `npm run build` behind a static site. ## Layer 2: one door into the scheduler A microVM only helps if every workload actually gets one. Nomad, our scheduler, will run whatever job it's handed, so nothing talks to it directly. Its API is firewalled off, and the only way in is an admission proxy that inspects each job before Nomad sees it. The proxy refuses any task that doesn't run under Kata, and any task that doesn't join the cell's own private network (host networking is refused by name). Scheduled (cron) jobs have to be exactly the shape we allow: overlapping runs prohibited, a fixed time zone, a run-time ceiling, no services, no ports. We built this check test-first: thirteen deliberately wrong scheduled jobs, each seen getting through before the check existed and refused once it did. They stay in the test. Requests to force a scheduled job to run early are refused, whoever sends them. It also blocks two scheduler endpoints that answer without a credential, one of which lists every running workload. Paths are normalised before matching, so `//v1/metrics` doesn't slip past a check for `/v1/metrics`. We treat the proxy as the boundary and assume our own client can be bypassed. A customer who pulls a deploy credential out of our tooling and hand-crafts a job still meets the same refusals. The same checks also run on every rendered job before we submit it, so a bad template fails at our end first. We've watched each of those checks fail. ## Layer 3: a network of one Each cell gets its own network bridge, with nothing else attached. Separate bridges don't route to each other, and on every worker a firewall rule drops traffic from any cell bridge to other cells, to anything on the platform's private overlay network, to RFC 1918 private address space, and to the worker's own services, including its DNS. The rule matches cell bridges by name prefix, so there's no list to update after each deploy. A new cell is covered as soon as its bridge exists, with no gap while a rule catches up. To check it, we read the drop counters from inside a live cell instead of reading the ruleset: attempts to reach the scheduler, service discovery, the registry and storage are all dropped, and the counters go up. Two lint rules guard this layer. Firewall chains may not use a drop policy, because a drop policy on the wrong hook cuts off the whole machine rather than the cell. And every job must declare its network, since a job that forgets gets a default network the firewall doesn't cover. Both lint rules have tests that make them fail. The next step for this layer is outbound traffic. A cell can reach the public internet, and there's no per-cell allowlist and no default-deny for outbound connections. We've built and measured a default-deny design with an allowlist in a prototype, but it isn't live. Until it is, think of a cell as a machine that can reach anything on the internet and nothing of ours or anyone else's. ## Layer 4: the front door A cell isn't reachable until something decides who may reach it. Before the gate existed, the wildcard hostname for cells answered every request with a 404, and we didn't serve a single app publicly until authorization was in place. From the outside, a cell that answers a stranger with a 200 looks exactly like one that answers its owner. Every cell has its own Cloudflare Access application, listing the people it's shared with. We could have used one wildcard application for all cells, but a wildcard authenticates people, not tenants: it would let any signed-in customer open any cell. Sharing is just that list. Adding or removing a person changes it without a redeploy, and removing the last person puts an explicit deny-all policy in place. The edge router checks the signed identity assertion itself: the signature against published keys, a pinned algorithm, issuer and expiry. It then strips cookies, `Authorization` and the assertion before forwarding, so the cell never holds a credential. A cell name that doesn't exist gets the same answer as one that does. The router's first version, early in development, only checked that the identity header was present. Our own adversarial test caught that the day it was written: with a test cell's login application removed, a header set to the literal string `forged` was accepted. Full signature verification replaced it that same day, long before any app was served publicly. Every configuration run now sends a forged assertion and one claiming the `none` algorithm, and both must be refused. Static sites get one more check. A valid signature proves the assertion came from our Access account, not which cell it was issued for, so for a static site the router also requires the assertion's audience to name that cell's own Access application. We tested it live: another organisation's genuine sign-in, replayed at a static site, gets a 403 and none of the site's bytes. Web cells don't have this check yet. For them, the cell's own Access application is the only per-cell binding until the router's check is extended to them. The episode also gave us the rule described further down: a test suite that has never sent a bad header can't tell you the check works. ## Layer 5: the API The control plane's API is where a token turns into an action. Tokens are stored as salted scrypt hashes, and we checked the whole table: none can be recovered from it. Comparison is constant-time, and a lint check catches any code that goes back to comparing with `==`. Every operation is bound to the token's org. Ask for another org's cell and you get the same "not found" as for a cell that doesn't exist, byte for byte. Scopes are enforced separately from identity, so a deploy token asking for an admin operation gets `forbidden`, a different answer from `unauthenticated`. Revoking a token takes effect on the next request, with no cache to wait out. Rate limits are per credential and apply only after authentication. In the other order, someone with no credential could make us allocate a rate-limit bucket for every token they care to invent. Forty unauthenticated requests get forty `unauthenticated` refusals and allocate nothing, and one token being throttled doesn't affect another in the same org. Authentication itself runs a bounded number at a time and refuses beyond that rather than queueing. A per-address limit at Cloudflare's edge sits in front of all of it. Every refusal has a fixed, typed error code, and a contract test pins those codes against the public client. Our own operational secrets are encrypted in the repository with SOPS and age keys, and reach machines only as files readable by root. The control plane stores no customer credential, just token hashes, which it can't replay. ## How we know a check works The forged-header test gave us one rule, and we apply it to every security check we add: > **A check counts only after it has been seen failing** against the code it protects: the unfixed file, a deliberately broken copy, or a live gate we removed on purpose. The cross-tenant test is the clearest case. It removes a real gate in front of a live cell, confirms the test now fails, then puts the gate back. On its last run it passed six of six, reading the marker each cell served, with the negative control live. It now includes a static site, where the other org's credential must get a 403 with no marker and no bytes. Authentication code gets mutants, for example a verifier that only checks a header is present, and each mutant has to fail the suite. Test doubles are held to the same standard. A review found a test double enforcing database rules on its own, which would have hidden a broken query, so we made it stop. Three mutants that break the real SQL now fail. Every security-relevant change also gets a separate adversarial review before it merges, from a reviewer whose only job is to break tenant isolation, authentication or scoping. On our device-login flow, the first round found that a poll with a caller-chosen value could collect someone else's token. That would have been a cross-tenant credential mint. We redesigned it before the flow was ever switched on. A test that has only ever passed hasn't shown it can catch anything. ## What's next A few pieces are designed and on their way: - Cells can reach the public internet. Allowlists and default-deny for outbound traffic are designed and prototyped, but not enforced. - There's no way to inject secrets into a cell yet. Keep keys out of your source anyway. - Spend caps and per-cell access logs are designed. Neither is built. - For abuse, per-account ceilings and takedown tooling are designed. The only live caps today are on scheduled jobs per org and on static sites, at most 10 per org. - The router's per-cell token check covers static sites only. Web cells don't get it yet. - We don't add a Content-Security-Policy to responses from your app yet. Our own login pages carry a strict one. When one of these ships, it will go through the same testing as the layers above, and we'll write it up. --- *Part of a series.

That gap is why the useful little tool your team built is still running on someone's laptop. Published: 2026-07-29 Canonical: https://agentcell.dev/blog/auth-pricing-cliff-small-software Markdown: https://agentcell.dev/blog/auth-pricing-cliff-small-software.md Someone on your team built something useful last week. A dashboard for the one number everyone keeps asking about. A tracker shaped like how your team actually works, instead of how Jira thinks it should. An agent wrote most of it, and it took an afternoon. It is still running on their laptop. Not because deploying is hard — deploying has been a solved problem for a decade. It is still on their laptop because the moment you want *one other person* to use it, you hit a wall that has nothing to do with your code. ## The wall Put the app on the internet and anyone can read it. So you need a login. And the moment you need a login, you are choosing an identity provider, wiring OAuth, modelling users and sessions, deciding what each person can see, and figuring out what happens when someone leaves the company. That is days of work. For an app whose actual business logic is two hundred lines. So you look for something to buy. And this is where it gets strange. ## Free, and then a cliff Here is what the identity vendors charge, as of July 2026: | Vendor | Free tier | The next step up | |---|---|---| | WorkOS | 1,000,000 MAU (AuthKit) | **$125/mo per enterprise SSO connection** | | Clerk | 50,000 monthly active users | Pro $100/mo, **Business $300/mo flat** | | Auth0 | 25,000 MAU | **B2B Essentials $150/mo for 500 MAU** | | Cloudflare Access | 50 users | $7/user/mo | Look at the shape of that. The free tiers are enormous — a million monthly active users, fifty thousand, twenty-five thousand. Then the next step is a hundred and twenty-five to three hundred dollars a month. Your app has three users. You are not near any free-tier limit and you never will be. But the thing you want — *let my three colleagues sign in with the work account they already have* — is a feature, not a volume. And it lives on the far side of the cliff. ## Why the pricing is shaped like that None of this is a mistake. These products are built for a specific customer: a B2B SaaS company selling to enterprises. WorkOS's per-connection pricing makes complete sense in that world. Each "connection" is one enterprise customer's identity provider, wired into your product so that customer's employees can log in. If you have forty enterprise customers, you have forty connections, each generating real revenue. $125 each is trivially worth it. Now apply that model to an internal tool. Your team wants to sign into its own dashboard using its own Google Workspace. That is *one connection*. You pay the same $125/month that a company would pay to onboard a paying enterprise customer — except this connection generates no revenue at all. It just lets Priya see a chart. The free tiers are shaped by the same logic. A million free MAU is generous because the vendor is betting you are building a consumer product that will grow, and they will monetize you on the enterprise features later. The free tier is sized for scale you do not have and do not want. **There is no tier priced for a permanently small audience.** Not a tier that is expensive — a tier that does not exist. Three to ten people, forever, who want SSO and will never need SCIM provisioning or audit exports or a compliance package. Nobody sells that. ## The other half of the problem Meanwhile, look at where you would host this thing. Render, Railway, Fly, Netlify, Cloudflare Pages — every one of them is excellent at taking your code and giving you a URL. Not one of them has an opinion about who is allowed to open it. Railway has no access control layer at all. That is not a criticism; it is a scope decision, and it is the same decision all of them made. So the two halves never meet. **Every host is auth-agnostic. Every auth vendor is hosting-agnostic.** Which means a three-person team building a three-person tool has to select two vendors, integrate them, and absorb two unrelated pricing models — one metered on compute, one metered on identity — to get to "deploy it, and let my colleague log in." For one small app, that is annoying. The team builds it anyway, or gives up. For the tenth small app, it is the whole ballgame. Nobody is doing that setup ten times. ## What the internal-tools platforms do instead The obvious answer is to use something that bundles this. Retool, Airtable, Power Apps — they all include identity, and that is genuinely part of why people buy them. But they solve it by charging per seat, which breaks in the other direction. Retool's Business tier is $50–65 per builder per month, and that is exactly the tier where SSO and governance live. Airtable bills every editor every month, whether they touched the base once or lived in it. Power Apps is $20 per user per month, and Microsoft retired the cheaper per-app plan in January 2026. Per-seat pricing works fine when an app serves the whole company. It is backwards when the app serves three people, because the cost scales with the users while the value scales with... also the users. There is no leverage. A three-user tool cannot carry a fifty-dollar-a-seat platform fee, so it never gets built there — and the fiftieth small tool, the one with two users, definitely never gets built there. That is the quiet reason so much small software stays a spreadsheet. Not because a spreadsheet is better. Because a spreadsheet does not require a procurement conversation. ## Auth is a platform property The framing mistake underneath all of this is treating authentication as something an *application* does. It made sense when applications were big. If you are building one product that serves a million users, that product should own its identity model, because identity is part of the product. But small software inverts every assumption there. The app is tiny. There are three users. The identity model is not a product decision — it is the same identity model your company already has, in Google Workspace or Okta or Entra, with the same people in it and the same person in HR removing them when they leave. Writing that logic into each small app is not just wasteful. It is worse than wasteful, because now the answer to "who can see the revenue dashboard" lives in code that an agent wrote at four in the afternoon, and nobody reviewed it, and it is different from the answer in the other nineteen tools. The correct place for that boundary is in front of the app, not inside it. An identity-aware proxy authenticates the request before it ever reaches your code, and hands the app a verified user. The app implements no auth at all. Sharing becomes a list of people, changeable without a redeploy. And when someone leaves, they are deprovisioned once — in the identity provider you already run — and lose access to all twenty tools at the same moment. That is not a novel architecture. Cloudflare Access, Google's IAP, and Vercel's deployment protection are all versions of it, and every large engineering organization builds some flavour internally. What has never existed is that pattern priced and packaged for someone who has three colleagues and a FastAPI app, rather than for a platform team with a Zero Trust rollout plan. ## What it should cost The test is simple, and it is not about the first app. It is whether your team can have twenty small tools alive at once without anyone doing arithmetic about it. Twenty tools, each with a handful of users, each occasionally opened, each behind your real identity provider. If the tenth one requires a pricing conversation, the tenth one does not get built — and the tenth one might have been the useful one. That means the marginal cost of one more small app has to be close to zero, which rules out per-seat, and it means org sign-in has to be at the bottom of the pricing page rather than gated behind an enterprise tier. Right now nobody offers that combination. Replit gates SSO to Enterprise. Vercel gates SAML and SCIM to Enterprise and charges $150/month for advanced deployment protection on Pro. Lovable is the most generous of the group and still puts SSO at its $50/month Business tier. The gap is not a small one, and it is not going to be closed by another auth SDK. It gets closed by treating hosting and identity as the same product — which is what we are building AgentCell to be. --- *AgentCell is the cloud for small software: one command to deploy the tool your agent built, and one email address to share it.
