UnoRouter
An open-source, OpenAI-compatible gateway: one key and one endpoint for models from every major AI provider, with automatic failover.
Overview
UnoRouter is a gateway for developers who are tired of keeping a separate key, SDK and bill for every AI provider. You point any OpenAI-compatible client at one endpoint, use one key, and choose models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and many others by changing a model string instead of rewriting code.
Routing is handled for you. When a provider is slow or down, requests move to a healthy one automatically, so a single outage does not take your app or your agent offline.
It fits into tools you already use: your own backend, Claude Code and other coding agents, CLI tools, and chat clients such as SillyTavern or Cline. There is also a built-in chat app that keeps conversations in your browser rather than on a server.
The entire stack is open source and public on GitHub, so you can read exactly how requests are handled. You can start on the free tier with no card, then pay as you go for usage. There is no subscription.

Frequently asked questions
Is there a free tier?
Yes. You can start without a card, and models marked free cost nothing within their usage limits. Paid usage is pay as you go.
Do I need to change my code?
No. UnoRouter speaks the OpenAI API, so you change the base URL and key and keep the rest.
Is it open source?
Yes. The whole stack is public at github.com/unorouter, and chat history in the web app stays in your browser.
