UnoRouter
Open source LLM gateway: one OpenAI compatible API for many model providers, with automatic failover
About
UnoRouter gives developers one OpenAI compatible endpoint and one key for models from OpenAI, Anthropic, Google, DeepSeek, Qwen and other providers. Each request is sent to a healthy provider. If a call errors or is rate limited, it is retried on another provider automatically, so an outage at one vendor does not take your product down. Moving over is a base URL change in existing SDK code, Claude Code, Cline or any OpenAI client. Spend and usage across all providers sit in one dashboard with a single balance. The project is open source. Free tier to start, then pay as you go.
