UnoRouter

UnoRouter is a single API for working with AI models from many vendors. Teams that use OpenAI, Anthropic, Google, DeepSeek or Qwen side by side can drop the separate accounts and keys and send everything through one OpenAI compatible endpoint.

Engineering teams keep their existing SDK code, change the base URL, and choose a model per request. When a provider slows down or fails, traffic moves to another healthy route automatically, so features built on LLMs stay up.

The project is open source end to end, the built in chat keeps history in the browser, and billing is a free tier followed by pay as you go credit with no subscription.
