About UnoRouter

Every AI company wants its own account, API key and billing. UnoRouter removes that overhead: one OpenAI-compatible key reaches models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and others. Existing apps that use the OpenAI SDK only need a new base URL, and coding agents like Claude Code and Cline work the same way. When one provider is down or rate limited, smart routing retries the request on another healthy provider, so your app keeps answering. The whole stack is open source and the chat app keeps conversations in your browser. Start on the free tier, then pay as you go with no subscription.

Questions about UnoRouter

Is UnoRouter free?

Yes. Every model ending in :free costs nothing, with a limit of about one request per minute per model. Paid models are pay as you go from a $1 top up, and that credit never expires. No credit card is needed to start.

Is UnoRouter safe to use?

Chats in the UnoRouter chat app are stored in your browser, not on our servers. Some providers keep or train on inputs; for those you see a notice or give consent once per provider before any request reaches them. All of the code is open source.

Is UnoRouter down?

Usually not: when a free model stops answering, every provider for that model is busy for a few minutes. Switch to another free model, or check the status page, which shows each model live.

Founder story Why we built one key for every AI model

We kept paying for separate accounts at OpenAI, Anthropic and Google just to compare answers, and every outage meant patching code at night. So we put one OpenAI-compatible endpoint in front of all of them, added routing...
