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:
- Deploy on Railway (compute bill #1).
- 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).
- 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.
