NanoHTTPD is a light-weight HTTP server designed for embedding in other applications, released under a Modified BSD licence. It is being developed at Github and uses Apache Maven for builds & unit testing. Nanolets are like servlets only that they have a extremely low profile. They offer an easy to use system for a more complex server application. We are currently in the process of stabilizing NanoHTTPD from the many pull requests and feature requests that were integrated over the last few months. The next release will come soon, and there will not be any more "intended" major changes before the next release. If you want to use the bleeding edge version, you can clone it from Github, or get it from sonatype.org (see "Maven dependencies / Living on the edge" below). Fully functional HTTP(s) server consisting of one (1) Java file, ready to be customized/inherited for your own project. Simple examples on how to customize NanoHTTPD.

Milkman is heavily inspired by Postman. But I got sick of all those electron-based applications that need ages and loads of memory to start up. Therefore, this is a JavaFx-based workbench for crafting requests/responses. It is not limited to e.g. HTTP (or more specifically rest) requests. Due to nearly everything being a plugin, other things are possible, like database requests or GRPC, GraphQl, etc. Request-types (e.g. Http Request), request-aspects (e.g. Headers, Body, etc), editors for request aspects (e.g. table-based editors for headers), importers, whatever it is, you can extend it. The core application only handles Workspaces with Environments, Collections, Requests, and their aspects. Several plugins are provided already that extend the core application to be a replacement for postman. Crafting and Executing Http/Rest requests with json highlighting. Support Proxy-server configuration and SSE.

Reactor Netty offers non-blocking and backpressure-ready TCP/HTTP/UDP/QUIC clients & servers based on Netty framework. With Gradle from repo.spring.io or Maven Central repositories (stable releases only). Reactor is a fourth-generation reactive library, based on the Reactive Streams specification, for building non-blocking applications on the JVM. Reactor is fully non-blocking and provides efficient demand management. It directly interacts with Java's functional API, CompletableFuture, Stream, and Duration. Reactor offers two reactive and composable APIs, Flux [N] and Mono [0|1], which extensively implement Reactive Extensions. Well-suited for a microservices architecture, Reactor offers backpressure-ready network engines for HTTP (including Websockets), TCP, and UDP.

Jetty provides a web server and servlet container, additionally providing support for HTTP/2, WebSocket, OSGi, JMX, JNDI, JAAS and many other integrations. These components are open source and are freely available for commercial use and distribution. Jetty is used in a wide variety of projects and products, both in development and production. Jetty has long been loved by developers due to its long history of being easily embedded in devices, tools, frameworks, application servers, and modern cloud services. With the direction of Java and the JakartaEE project (formerly JavaEE) in 2020, the current recommended version of Jetty for use depends upon the servlet api version, desired licensing, and package namespace as well as the intended Java version.

Proxyee is a JAVA-written HTTP proxy server library that supports HTTP, HTTPS, and WebSocket protocols, and supports MITM (Man-in-the-middle), which can capture and tamper with HTTP, and HTTPS packets. The CA certificate (src/resources/ca.crt) from the project needs to be imported to a trusted root certificate authority. The CA certificate (src/resources/ca.crt) from the project needs to be imported to a trusted root certificate authority. You can use the CertDownIntercept interceptor to enable the web certificate download feature.
