UnoRouter

UnoRouter is an OpenAI-compatible gateway that puts 300 AI models behind a single API key. Instead of holding separate accounts, keys and invoices for OpenAI, Anthropic, Google, DeepSeek, Qwen and Mistral, you point your existing SDK at one base URL and switch models with a string change.

Because it speaks the OpenAI API, it drops into code you have already written, and into Claude Code, SillyTavern, RisuAI, Cline and other clients with no adapter layer. Smart routing spreads traffic across healthy providers and fails over automatically, so one provider going down does not take your app with it.

The whole stack is open source, and chat is local-first: conversations stay in your browser rather than on our servers, which makes the privacy claim auditable instead of a promise. There is a free tier to start and pay-as-you-go after that, with no subscription.
