Built for the player, not the catalogue.
Thirty years on, DOOM is more alive than the day it shipped. Cacowards every December, new megawads every month, total conversions that out-design studios with real budgets. And playing any of it still meant the same routine: install a source port, find the right IWAD, sort out config files and load orders. This site exists so you can just play — any mod, no installing anything.
The engine runs on your machine, in your tab. Base games download from public archives or from your own copy, mods are read off your disk and never leave it, and your saves are yours to export. That's the whole idea.
A fan project for playing classic DOOM, and the mods people keep making for it, in a browser. It runs UZDoom, our build of GZDoom compiled to WebAssembly. Pick a game and play, or add your own WAD and PK3 files first. Nothing to install, and an account is optional.
Standing on giants.
