UnoRouter is an open source LLM gateway for developers who are tired of keeping a separate key, bill and SDK for every model provider.
- One endpoint speaks the OpenAI API, so existing code, Claude Code, Cline or SillyTavern work by changing the base URL
- Models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and more behind that one key
- Smart routing with automatic failover when a provider goes down
- Chat is local first: conversations stay in your browser
- Free tier to start, then pay as you go with no subscription
