UnoRouter

About UnoRouter

UnoRouter is an AI API gateway that gives developers a single API key for 315+ AI models from 47+ providers, including OpenAI, Anthropic, Google, Meta, Mistral and DeepSeek. Teams point one OpenAI-compatible endpoint at UnoRouter and switch models by changing a string. Smart routing selects a healthy provider per request and automatic failover retries elsewhere when one degrades or rate-limits. Existing tooling works without code changes: coding agents, chat clients, CLI wrappers and any SDK already targeting OpenAI. A browser-based chat client with free models needs no signup or key.
