The KDE Plasma desktop, running in your browser

A real Debian userland with KDE Plasma, compiled to WebAssembly and run by gex, right here in the page. Nothing to install and no server doing the work: it runs on your machine.

Konsole, Dolphin and Kate, with KWin drawing the windows
apt works: apt update, then apt install <package> from Konsole
One download of about 200 MB, then it starts in about a minute

Best in a desktop browser with plenty of memory.
