A chat product, not a demo.

Everything that normally stands between an API key and something you could charge for — already built, typed, and tested. Sign in to use the app you'd be shipping.

What do I actually get?

Everything a chat product needs before you write your first feature:

  • Streaming chat — token-by-token over AG-UI, no hosted gateway in between
  • Typed tools — client and server, with an approval step before anything runs
  • Provider switching — Anthropic, OpenAI, Gemini, or your own endpoint
  • Image generation — a second panel sharing the same thread history
  • Accounts and threads — Better Auth over Postgres, conversations that persist

Plus rate limiting, a Playwright and Vitest suite, and a Docker deploy that runs migrations before it swaps containers.
