About

UnoRouter

UnoRouter is an LLM gateway for developers and AI app builders. Existing OpenAI SDK code, Claude Code and chat clients work after changing the base URL, and every model behind it is selected by name. Requests fail over to another healthy provider when one is down. The code is public on GitHub, the chat stores history in the browser, and billing is a free tier followed by pay as you go.
