UnoRouter is an AI API for makers who prototype on free models first and switch to premium ones from OpenAI, Anthropic or Google with the same key.
How it works
You get one OpenAI-compatible endpoint. Behind it sit models from OpenAI, Anthropic, Google, Meta, DeepSeek, Qwen and Mistral, and a set of free models you can call without adding a card. When a provider has an outage, smart routing fails over to another one so your app keeps answering.
Where to use it
- Your own code, through any OpenAI SDK
- Coding agents such as Claude Code, Cline and OpenCode
- The built-in web chat, which is local-first and keeps conversations in your browser
Cost
Start on the free tier, then pay as you go. There is no subscription, and the whole project is open source.
