UnoRouter is a gateway for large language models that speaks the OpenAI API. You point your existing SDK or client at one base URL, keep one key, and pick models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and many other providers by changing the model string.
Why it exists
Running the same app against several AI vendors usually means several accounts, several keys, several invoices and slightly different SDKs. UnoRouter collapses that into one endpoint and one balance.
What you get
- Drop in compatibility: works with the OpenAI SDKs, Claude Code, Cline, SillyTavern, RisuAI and other clients that accept a custom base URL.
- Failover routing: when a provider times out or errors, the request is retried on another healthy provider instead of failing your app.
- Open source: the whole stack is public, so you can read how routing and billing work.
- Local first chat: the built in chat keeps conversations in your browser rather than on a server.
- Simple pricing: a free tier to try it, then pay as you go with no subscription.
