UnoRouter

UnoRouter is a fully open source AI gateway for makers who want to see how their traffic is handled, giving them one OpenAI-compatible key and routing that steps around provider failures. Every layer is published on GitHub: the web app, the backend that holds your account, the gateway that forwards requests and the tooling that keeps the provider list in sync. Nothing about how a request is chosen, retried or billed is hidden behind a closed service. In practice you point an OpenAI SDK, Claude Code, Cline or OpenCode at the UnoRouter base URL and pick a model by name. If the route serving that model errors or hits a rate limit, the gateway moves the call to another healthy route, so your app keeps answering. Privacy follows the same idea. The chat app on the site keeps your conversations in local browser storage, so there is no chat history on our servers to leak. Start with the free models and the free tier, no card needed, then top up and pay as you go. There is no subscription.
