Netty is hardly the example of a hype driven framework. I'm not sure when it was first released but I've found references from version 2.0 in 2004. It may be older than HAProxy. Netty is a far more robust, faster, and easier to use framework for TCP proxies than the one the author cooked up and I'm getting downvoted like crazy for saying it. It's also used internally by Google, Twitter, and netflix. It's embedded in the GRPC library, Cassandra's database driver, Play framework, and Vert.x among many others. Check their related projects page https://netty.io/wiki/related-projects.html https://netty.io/wiki/related-projects.html Netty is a phenomenal project, and had the author known about it, I doubt he would have spent the time writing his own TCP proxy.
