I've created my first GUI in Rust. I made a wrapper for #paperage, which is an application for saving encrypted secrets on paper.
I had to tweak paper-age a bit, but now you can use it in the browser using #WASM.
It's still a bit messy, but it should work. And of course, there's #nix support.
You can find it on GitHub here: https://github.com/renesat/paper-age-gui
P.S. Thanks for the idea, @iuvi. You can start testing
