UnoRouter

UnoRouter is an OpenAI-compatible API gateway. One key and one request format reach models from OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and many other providers, so you stop maintaining a separate integration for each vendor.

Because the endpoint speaks the standard chat-completions format, existing OpenAI SDKs work unchanged. Point the base URL at UnoRouter and your current code keeps running, including streaming, tool calling and vision requests.

Requests fail over between providers automatically, so one upstream outage or rate limit does not take your application down. Every call is logged with its token counts and cost, which makes spend across several providers visible in one place instead of scattered across vendor dashboards.

There is a free tier to start on, with pay-as-you-go pricing afterwards and no subscription.
