Does Railway have a region in France?

No, its European region is in Amsterdam. while hosts in France.

Does my agent see my variables?

On Railway, it can retrieve them, even into a .env file. On while, it never sees your keys.

Which one has a spending cap?

Railway stops your services at the limit you set. On while, each project has its budget: a change that would exceed it waits for your approval, an alert goes out at 80% and at 100%, and a live app is never cut off.

Railway vs while: the French alternative for your AI agent

Railway is one of the most pleasant hosts for an AI agent. while goes further on production: what could break it waits for your approval, your agent never sees your keys, and your data stays in France.

What changes between Railway and while

What matters	Railway	while
Who it’s for	Developers who want to deploy fast, with or without an agent	People who build their apps with an AI agent, solo or as a team
Your AI agent	An MCP server, with OAuth, on the projects you choose¹	Connected over MCP, with OAuth: it deploys, creates the database, reads the logs and fixes things
What protects production	A confirmation your AI tool asks for, if it honors the flag on destructive actions¹	Sensitive actions, like deleting a production database, wait for a person
Your API keys	Your agent can retrieve your variables¹	Your agent never sees them: they stay in while
The database	PostgreSQL in a single request, from a template¹	PostgreSQL in while, backed up every day, with point-in-time recovery
In France	No, Amsterdam is the closest²	Yes, with Nextmap, a French company
To get started	Hobby at $5 per month, with up to $5 of usage included³	A trial without an account. Then €0 to get started, and €13.75 per month for an app and its database

Railway, one of the smoothest hosts for an agent

With OAuth, you choose which projects your agent sees, and it creates a PostgreSQL database in a single request¹. Railway bills by usage, and it stops your services at the spending limit you set^3,4.

With while, your AI agent does the rest

Your agent deploys, over MCP. It writes while.yaml, creates the database, reads the logs and fixes things, with no command line to learn.
Nothing serious happens without you. Deleting a production database waits for your approval, before it runs, and every action is recorded in a signed activity log.
Your keys stay secret. Your app uses them, your agent never sees them.
Your colleagues sign in with the company account. Google Workspace or Microsoft 365, on the Pro plan, with no sign-in page to code.
A mistake is quickly undone. In the 30 minutes after a deployment, the previous version comes back in a second, and your database goes back to a precise moment.

Moving from Railway to while

Take over your app

You, to your agent: Move our Railway app to while.

Your agent writes while.yaml from your code. A Node.js, Python or Go app starts without a Dockerfile, the others with yours.

Copy your PostgreSQL database

You, to your agent: Copy our PostgreSQL database to while.

Your agent exports the database with pg_dump, then loads it into while.

Carry over your variables

You, to your agent: Carry over our environment variables.

Your agent carries your settings over to while. You enter your secret keys yourself: it never sees them.

Which one to choose

Choose Railway if your apps must stop dead at a spending limit, production included, and France doesn’t matter.
Choose while if your AI agent deploys your apps, and you want to stay in control without reviewing every command, with your data in France.
