This is a full-featured HTTP server and client in plain Java without the use of any libraries. The client and server will use non-blocking NIO in order to provide the highest performance possible.
The server is further along than the client.
I work for this company and know the engineers who wrote it. We moved on from Tomcat because of how slowly it implemented new features (due to having to stick to the servlet and other JEE specs), tried netty and ran into some performance concerns, and now are writing this with NIO. They looked around to see if there were any other NIO java HTTP servers and didn't find anything.
They also wrote one of the popular JWT libraries: https://github.com/FusionAuth/fu...
