Questions before you install.

Getting started →
Is SuperChat a chat app?

No. It is the library you build an agent’s answers with, inside your own product.

Does the model write UI code?

No. It picks a card kind and fills in a spec. The spec is validated before anything renders, and your renderers decide how it looks.

Do I need a hosted gateway?

No. The backend is one route handler on your own server. It holds your key, runs your auth and records usage.

Which providers does it support?

OpenAI (Responses and Chat Completions), Anthropic, and OpenAI-compatible endpoints.

Is it free?

Yes. Apache-2.0.
