UnoRouter

UnoRouter is for developers and teams who build on large language models and are tired of managing a separate account, key and bill for every provider. It gives you one OpenAI compatible API endpoint and one key for models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and many others. Requests are routed to a healthy provider and fail over automatically, so one outage does not take your product down. It works with OpenAI SDKs and with clients such as Claude Code, Cline and SillyTavern. The project is open source and its web chat stores conversations in the browser. Start on the free tier, then pay as you go with no subscription.
