ActiveJ

ActiveJ is an alternative Java platform built from the ground up as a replacement of Spring, Spark, Quarkus, Micronauts, and other solutions. It is minimalistic, boilerplate-free, and incomparably faster, which is proven by benchmarks. ActiveJ has minimum third-party dependencies, yet features a full stack of technologies with an efficient async programming model and powerful DI library ActiveInject.

ActiveJ consists of several loosely coupled components that complement and empower each other: async core (Promise, Eventloop), efficient I/O processing (CSP, Datastream), high-performance Jetty and Netty alternatives that can be used independently of ActiveJ (HTTP, Net), and handy boot utilities (Launcher, Service Graph, etc).
