I love the aesthetics of terminals and I’m not the only one, there is a whole subreddit dedicated to people sharing their desktops and showcasing different terminal setups. Last year I spent working on an innovative WebAssembly runtime called Lunatic. Recently we landed TCP support and I was super excited to start building real world applications with it, and what would be a better fit than a terminal based chat server with a retro vibe?

It took me around a week to build it with Rust + Lunatic and you can check out the code here. If you would like to try it out you can connect to it with:

They all compiled to WebAssembly without issues. I just needed to provide a telnet backend for TUI, but I could reuse most of the code from the termion crate (sadly it has no Windows support for now).
