UnoRouter

UnoRouter is an open source, OpenAI-compatible gateway. One API key reaches Claude plus models from OpenAI, Google, DeepSeek, Qwen and other providers, so you can point Claude Code, Cline, an OpenAI SDK or a chat client like SillyTavern at a single base URL and switch models by name.

It is for developers who want to compare or mix models without a separate account and bill per vendor. When a provider has an outage, requests fail over to a healthy one. The web chat keeps conversations in your browser. Free models and a free tier to start, then pay as you go with no subscription.
