Classic DOS DOOM vs. source ports

This page runs the original DOOM.EXE DOS binary in DOSBox — the same executable that shipped on floppy disks in 1993. No source port, no Wine, just pure DOSBox emulation. WASD moves (remapped via DOSBox), Ctrl fires, Space opens doors. Arrow keys also work.

Want a source port?

DOOM's engine was open-sourced by id in 1997, spawning dozens of modernized ports like Chocolate Doom. These run the same shareware WAD with higher resolutions and fixed bugs. Those are desktop programs, though — this page runs the original DOS build, which is the version that needs no setup at all.

Frequently asked questions

Can I play DOOM online for free with no download?

Yes. Episode one (Knee-Deep in the Dead) was released as free shareware in 1993 and is still freely redistributable. ExeBrowser runs the real DOS build in your browser — nothing to install.

Can I play DOOM unblocked at school or work?

Usually, yes. There is no installer and no executable to run: the page downloads about 2 MB of game data and a DOSBox build compiled to WebAssembly, then runs it inside the tab like any other web page. Nothing touches the machine's filesystem and nothing needs admin rights, so the restrictions that stop people installing games don't apply. The one thing that will stop it is a network filter blocking exebrowser.com itself — no browser game can work around that.

Is this real DOOM or a remake?

The real, original executable, running unmodified. ExeBrowser doesn't re-create the game; it runs id Software's actual DOS binary inside DOSBox compiled to WebAssembly, rendering to a browser canvas.

What are the controls for DOOM in the browser?

Click the game canvas to capture input. WASD moves (W=forward, S=back, A=turn left, D=turn right), Ctrl fires, Space opens doors, and the number keys switch weapons. Arrow keys also work. Press Esc to release the mouse back to the page.

Is it legal to play DOOM here?

Yes, for the shareware episode — id distributed it to be freely copied unmodified at no charge. The registered episodes and DOOM II are commercial and aren't included; buy those from id or Steam.

Why might DOOM run slowly in the browser?

An x86 CPU is emulated inside WebAssembly, so you get roughly 10–40% of native speed. DOOM is light enough to play at full speed on most modern laptops; older tablets and Chromebooks may feel slower.

Does it save my progress?

Yes, and not only from the game's own save menu. Close the tab mid-level and the next visit offers to put you back exactly where you were, because the whole emulator state is snapshotted to your browser's storage. Nothing is uploaded and there is no account — the save lives on the device you played on, which also means it does not follow you to another computer.
