About This DOOM Port
It runs UZDoom, a GPL v3 engine in the GZDoom family, through the uzdoom-wasm port. Files stay on your machine. The page calls itself an experimental tech demo and suggests installing GZDoom locally for the smoothest experience.
It uses a service worker to enable the browser isolation the engine needs, which does not work inside another site, so the Play button opens it in a new tab.
