UnoRouter is an OpenAI-compatible gateway that puts models from OpenAI, Anthropic, Google, DeepSeek, Qwen and many other providers behind a single endpoint and a single key. Switching from one model to another is a change to the model string, not a new SDK or a new billing account. Requests are routed across healthy providers and fail over automatically when one goes down. The whole stack is open source, the built in chat keeps conversations in your browser, and a set of models can be used for free before any pay as you go spending.

### What it does
- Exposes many providers through one OpenAI-compatible endpoint
- Routes requests to healthy providers and fails over automatically
- Bills usage pay as you go with no subscription
- Offers a local-first chat that stores conversations in the browser

### Who it is for
- Developers who call several LLM providers from one app
- Teams that want failover between AI providers
- Users of Claude Code, Cline, SillyTavern and other OpenAI-compatible clients

### Pros
- One key and one bill instead of one per provider
- Drop-in for existing OpenAI SDK code
- Open source stack
- Free models available to start

### Cons
- Pay as you go only, no fixed monthly bundle
- Model availability follows what upstream providers offer
