UnoRouter

UnoRouter is a small, open source LLM gateway built by an indie team that got tired of keeping a separate key, bill and SDK for every AI provider. You get one OpenAI compatible endpoint and one key, and switching between GPT, Claude, Gemini, DeepSeek or Qwen becomes a change to the model string. When a provider goes down, requests are routed to a healthy one automatically. The chat is local first, so conversations stay in your browser. Free tier to start, then pay as you go with no subscription.
