An open source, OpenAI-compatible gateway to every major AI model

About

UnoRouter gives builders one API key and one endpoint for models from OpenAI, Anthropic, Google, DeepSeek, Qwen and others. Because it speaks the OpenAI format, existing SDK code and tools like Claude Code or Cline work after a base URL change. Traffic is routed across healthy providers with automatic failover. The full stack is open source, the chat keeps history in the browser, and billing is a free tier followed by pay as you go.
