Kaeso

Kaeso is an open-source AI gateway that you deploy on your own infrastructure. Applications use OpenAI- and Anthropic-compatible APIs while you manage provider keys, routing, usage and access centrally. It includes SSO, roles, budgets, rate limits and request logs. The stable release is 0.5.6 and the source code is MIT-licensed. Infrastructure and upstream model-provider usage are separate costs; free software does not mean free inference. Kaeso is a gateway layer, not an LLM model or a hosted inference service.
