Apiman

Apiman is an open source API management platform for controlling the full API lifecycle. It exposes existing APIs to external consumers securely and gives teams a central place to discover and govern those APIs.

It pairs an API design and configuration layer with a fast, modular runtime. You extend behavior with simple Java plugins, and a skinnable developer portal lets external developers browse and sign up to APIs in a marketplace-style experience.

Apiman 4 is the current line of active development. It runs on Java 11 or later and ships as container images and packaged binaries, so you can start from the quickstart or run it as a container.
