H2Check is a tool for checking whether servers support HTTP/2, the second version of the HTTP protocol used for web communication. Released in May 2015, HTTP/2 was designed to improve web page loading speed through compression, multiplexing, and request prioritization while maintaining compatibility with existing HTTP concepts. The tool is for website administrators and developers who need to verify HTTP/2 implementation on their servers.

It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)
