In their own words
YoloRouter
YoloRouter is a gateway that sends AI model requests to multiple providers through a compatible API. It accepts OpenAI Chat Completions and Responses, Anthropic Messages, and Gemini generateContent protocols, and translates between supported formats when the client and provider use different ones. Routing includes ordered provider candidates, failover, and pooling of upstream keys; the documentation lists access to providers including OpenAI and Anthropic through one endpoint. Streaming uses Server-Sent Events with usage tracking. Alongside chat, the gateway exposes OpenAI Images and Videos APIs, with billing based on delivered images or video seconds. It can compress bulky tool output before forwarding it upstream and report measured savings. API keys can have model allowlists, rate and concurrency limits, budget caps, expiry, and revocation. The admin console supports multiple users, single sign-on, usage visibility, and account controls. Self-hosted deployment is a single binary with an embedded console, SQLite by default, or optional PostgreSQL. The self-hosted plan is free. Cloud billing uses top-up credits, with no subscription or minimum spend.
