sudo npm i -g appnativefy
Star it if you like it, README is in detail.:)
I've made a CLI tool, using Node.JS and Shell scripting to wrap any website into an executable AppImage format, by making an AppImage there is no further execution required. Just click and run.
Plus, it also changes the scrollbar to minimal black style make it look a little less hideous than the standard one present.
Created AppImages will be built to ~/appnativefy
Currently tested on Gentoo, Ubuntu, KDE Neon, Garuda.
