Buildy turns ideas you describe in chat into real, hosted web apps with their own URL and a database, so any AI can use and update them later.

How do I build an app with Buildy?

Ask any AI to build it: ChatGPT, Claude, or a coding agent. Buildy gives the AI a way to create the app, give it a real URL, and store its data.

Does my Buildy app keep working after I close the chat?

Yes. Each Buildy app has its own URL and persistent storage. You can open it later in a browser, on your phone, or from a different AI chat and the data is still there.

Can other AIs use a Buildy app I created?

Yes. Buildy apps are AI-ready: any AI that supports MCP, or that can make HTTP calls, can read and update the data in your app.

How much does Buildy cost?

You can build and host Buildy apps for free during the open preview. No signup is required to try one of the starter apps.

Software that’s finally yours.

Your agent builds an app you can keep using and updating. It stays live at its own URL after the chat ends.
