UnoRouter

UnoRouter is a developer tool for calling large language models through one OpenAI compatible endpoint. Keep the OpenAI SDK you already use in Python, TypeScript, Go or any other language, set the base URL to UnoRouter, and pick Claude, Gemini, GPT, DeepSeek or Qwen per request with the model field.

Under the hood it routes each call to a healthy provider and retries elsewhere when one errors, so a single upstream outage does not break your build or your production app. It also plugs into coding agents such as Cline and Claude Code.

Open source across the whole stack, free tier to start, pay as you go afterwards with no subscription.
