Jet offers four modules: Common, Server, OpenAPI Annotations, OpenAPI Annotations Plugin, and Client.
Jet is a wrapper around the excellent Jetty web client and server library. Jetty provides the battle-tested low-level protocol handling, while Jet focuses on providing a modern and consistent interface with superb documentation and an amazing developer experience.

The Client module is a still a WIP, but the Server, OpenAPI Annotations, and OpenAPI Annotations Plugin modules are production-ready!
