This is my side hobby, a server side TUI protocol with a light browser like client that can navigate any TUI.

The primitives are good enough to build anything you want. Right now I'm trying to figure out how to make better libs and tooling for creators (mainly myself) so I can crank out lots of examples apps that showcase the power of TUIs where you don't need a dedicated executable for each one.
