UnoRouter
A unified API and browser chat client that gives access to 326+ AI models through OpenAI-compatible endpoints.
UnoRouter gives developers, AI builders, and power users a single API key for accessing hundreds of AI models across dozens of providers. Instead of creating separate accounts and integrations for every model vendor, you connect once and route requests through one OpenAI-compatible API. The platform also includes a browser-based chat client, making it easy to test models or chat without writing code.
It's designed for developers building AI applications, autonomous agents, coding assistants, chat clients, and automation workflows that need reliable access to multiple model providers through one endpoint. Automatic provider routing and failover help keep requests running even if an upstream provider becomes unavailable.
