About UnoRouter: free AI API key for every major model

UnoRouter is a free AI API gateway for developers who want every major model behind a single key instead of a separate account per provider.

Sign up, copy one key, and point any OpenAI-compatible SDK or client at the UnoRouter base URL. From there GPT, Claude, Gemini, Llama, DeepSeek, Qwen and Mistral models are a model name away, and a set of free models lets you build and test without paying anything up front.

Requests are routed across healthy providers, so when one upstream fails the call moves to another instead of erroring out. The same key works in your own code, in Claude Code and Cline, and in chat clients such as SillyTavern.

The full stack is open source, and the built-in chat keeps conversations in your browser rather than on a server. Pricing is a free tier followed by pay-as-you-go credits, with no subscription.
