UnoRouter

UnoRouter is an AI model gateway for SaaS builders who want to ship AI features without wiring up a different provider for each model. One API key and one OpenAI-compatible endpoint give you models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and more, so moving a feature from one model to another is a config change.

It is built for production traffic: every request is routed to a healthy provider, and if that provider errors or times out the call fails over to another one automatically, so an upstream outage does not become your outage.

It also works outside your own code. Claude Code, Cline, OpenCode, LibreChat and other clients that accept a custom base URL can use the same key.

Pricing is simple: a free tier with free models and no card, then pay-as-you-go credit with no subscription. The whole stack is open source, and the web chat keeps conversations in your browser.
