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.

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. You can use the CertDownIntercept interceptor to enable the web certificate download feature.

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.

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.
