UnoRouter
Open source LLM gateway with one OpenAI compatible key for many model vendors
About UnoRouter
UnoRouter is an open source, OpenAI compatible gateway for large language models. Instead of managing separate accounts for each vendor, you get one API key that reaches models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and more. The router picks a healthy upstream for every request and fails over automatically if a provider errors or slows down, so your app keeps answering. Existing OpenAI SDK code works after changing the base URL, and it plugs into Claude Code, Cline, SillyTavern and RisuAI. The built in chat is local first: your history stays in the browser. Pricing is a free tier to start, then pay as you go with no subscription.
