Apiman is a flexible open source API Management platform aimed at enterprise users. It combines a rich API design and configuration layer with a fast, modular runtime, and can be customised via simple Java plugins. It covers the full API Management lifecycle, including governance, security, documentation, monitoring, and a developer portal. Apiman Gateways are decoupled from the Apiman Manager so gateways keep running even if the manager goes down.
