Open-source AI gateway you run yourself, with single sign-on and request logs

Kaeso is an open-source AI gateway that sits in the request path between your apps and model providers. It handles provider keys, routing, limits and request logs in one place, with single sign-on for each organization and MCP server management.

The gateway is written in Rust and licensed MIT. Teams self-host it and connect their own providers, including Cerebras as a built-in provider since release 0.5.6. A console shows usage, spend and an audit log.
