Open Source Java HTTP Servers

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards: WMS, WFS, WCS, WPS and REST

HSQLDB is a relational database engine written in Java, with a JDBC driver, conforming to ANSI SQL:2023. A small, fast, multithreaded engine and server with memory and disk tables, LOBs, transaction isolation, multiversion concurrency and ACID.

A free and open source manga reader server that runs extensions built for Tachiyomi. Suwayomi is an independent Tachiyomi compatible software and is not a Fork of Tachiyomi. Suwayomi-Server is as multi-platform as you can get. Any platform that runs java and/or has a modern browser can run it. This includes Windows, Linux, macOS, chrome OS, etc. Follow Downloading and Running the app for installation instructions.

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.

http-kit is a minimalist, event-driven, high-performance Clojure HTTP server/client library with WebSocket and asynchronous support. A simple, high-performance event-driven HTTP client+server for Clojure. HTTP Kit is an (almost) drop-in replacement for the standard Ring Jetty adapter. So you can use it with all your current libraries (e.g. Compojure) and middleware. Using an event-driven architecture like Nginx, HTTP-kit is very, very fast. It comfortably handles tens of thousands of requests/sec on even midrange hardware. Here is another test about how it stacks up with others. It's not only fast, but efficient! Each connection costs nothing but a few kB of memory. RAM usage grows O(n) with connections. Written from the ground-up to be lean, the entire client/server is available as a single ~90kB JAR with zero dependencies and ~3k lines of (mostly Java) code. Synchronous is simple. Asynchronous is fast & flexible.

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.

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.

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.

Feign is a Java to HTTP client binder that was built primarily to make writing Java http clients easier. Inspired by previous projects Retrofit, JAXRS-2.0 and WebSocket, Feign was designed to reduce the complexity that is often involved in binding the Denominator uniformly to HTTP APIs, no matter the ReSTfulness. Feign works by processing annotations into a templatized request, to which arguments are applied in a straightforward manner before output. While it may only support text-based APIs, it simplifies system aspects dramatically and makes it much easier to unit test your conversions. Feign makes use of great tools like Jersey and CXF for writing Java clients for ReST or SOAP services. It also lets you write your own code on top of http libraries, and connects your code to http APIs with little overhead.

This library is based on the Http protocol and encapsulates the OkHttp network request framework. It is easier to use than Retrofit, supports RxJava, RxJava2, supports custom caching, and supports batch breakpoint download management and batch upload management functions. Completely imitating WeChat's image selection library, it comes with rectangular image cropping and circular image cropping functions, which can be downloaded and used if necessary. Similar to Qzone, WeChat Moments, Weibo homepage, etc., the Jiugongge control that displays pictures automatically determines the size of the picture and the size of the control according to the number of pictures, uses the Adapter mode to set the picture, provides external interface callbacks, and uses the interface to load pictures, supporting arbitrary Image loading frameworks such as: Glide, ImageLoader, xUtils3, Picasso, etc., support click on the image to preview the large image in full screen.

LocalServer is a Web Server software for Windows that allows you to make your Computer into a Web Server Locally in which there is the Apache Server, PHP, and MySQL Server, which has been summarized in a single container setup.exe. The advantages of this software is Free except you do not need to advance other similar software, which is installed by default on your computer, because the Apache Server and MySQL Server will be installed on LocalServer first time on a different port, the Apache server running on port 4008 and MySQL Server running on port 3308. The latest version has been on the Release of version 1.0.1 that is made on the date of 26-10-2012, which has been running stable on Windows devices with the addition of the mail server that Mercury mail. Hopefully LocalServer useful for you to use, and congratulations creative with LocalServer Thank you!
