Every Railway project starts with code that already exists, written by you or, increasingly, your agent. Agents now handle the operating too: many of you ask yours to deploy services, provision resources, or troubleshoot issues.

But if all you have is an idea, no code, no repo, there hasn't been a way to build it on Railway directly.

We thought, can we make a good zero to one experience, that takes advantage of our platform that helps you scale from one to one million? dev.new is that missing piece, now in preview: a zero to deployed experience on the platform.

Log in with your Railway account and describe what you want to build. The Railway Agent builds the app while you watch it take shape in a live preview. And because it's the Railway Agent under the hood, the same chat handles more than UI tweaks: ask it to add a database, change the domain, or wire up variables.

When you're happy with what you have, publish, and the app deploys into your Railway account.

Build a one-off internal tool, or grow the same app into a production system, ultra-fast, using our new in-place builder. Either way, there's no migration cliff between the prototype and the real thing.

You'll notice dev.new is a separate experience from the Railway dashboard, that said, your dev.new projects are Railway Projects under the hood, use the agent or go to the dashboard to perform any advanced configuration. Down the line, the goal is to fold everything into one unified experience.
