UnoRouter

UnoRouter is an open-source, OpenAI-compatible API gateway that reaches 300 AI models through a single key, covering OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek and Qwen.

Running several model providers normally means a separate integration, key and invoice for each one. UnoRouter collapses that into a single base URL, so switching models is a string change rather than a rewrite. Existing OpenAI-compatible code keeps working unchanged, including Claude Code, Cline, SillyTavern and RisuAI.

Smart routing picks a healthy provider for every request and fails over automatically when one rate-limits or goes down. Usage logs record cost and token counts per request, so spend stays visible. Chat is local-first, meaning conversations stay in the browser rather than on a server.

There is a free tier with genuinely free models, then pay-as-you-go pricing with no subscription and no minimum commitment.
