Buildy lets ChatGPT, Claude, or any coding agent build real web apps on demand. The app works across agents, so you can build it once and keep using the same app/data from ChatGPT, Claude, Codex, or wherever your agent runs.

Chat apps disappear. Buildy apps stick around.

Ask any AI to build it. Buildy gives it a real URL and a database — and your AI can use it and update it, long after the chat is closed.

How it works

One app. Hosted by Buildy. Open anywhere.

◆ Your data lives in one place — every surface shows the same thing. ◆ One datastore — read/write via query_app · mutate_app · POST /app/<id>/api/<op> — from the UI, the API, or any connected agent.

Starter apps you can customize.

Use one as-is, or ask AI to personalize it.
