UnoRouter

UnoRouter is an LLM gateway for anyone building on several AI models at once. Instead of signing up with every vendor, you call one OpenAI compatible endpoint with one key and choose the model per request: OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and more are behind it. Requests are routed to healthy upstreams and fail over automatically when a provider has trouble. It works in your own code and in tools like Claude Code, Cline, SillyTavern and other OpenAI style clients. The code is open source, chat history stays in your browser, and you can start free and pay as you go later, with no subscription.
