UnoRouter

UnoRouter is an LLM gateway for developers who would rather write code than manage vendor accounts. Point any OpenAI SDK, Claude Code or Cline at one base URL, use one key, and pick Claude, GPT, Gemini, DeepSeek or Qwen by model name. Requests that fail upstream are retried on another healthy provider automatically. The whole stack is open source, the web chat stores history in your browser only, there are free models to experiment with, and paid usage is pay as you go without a subscription.
