Spartan (Github repo) is a hobbyists' protocol that returns to plain text over network sockets.

This is where HTTP started but as the requirements for a protocol that basically underpins the global information and service system has grown it has been increasingly impractical for an individual to implement a reasonably complete HTTP 2 or 3 server.

But what if, instead of selling things you were just interested in sharing information and had an interest in understanding more of your protocol stack? Well Spartan is for you.
