The Simpsons: Hit & Run WASM

The Simpsons: Hit & Run - WASM runs the PC version of The Simpsons: Hit & Run (2003) in a browser tab. You do not need your own game files: the site streams the game data from its server as you play. It is aimed at desktop browsers; phone support is untested. The site was working when we checked on 17 October 2026.

What it is

The port was posted to Hacker News on 21 April 2026 by the user calebj0seph under the title “The Simpsons Hit and Run Ported to WebAssembly and WebGL”, and it is hosted on a Cloudflare Workers address under the name cjoseph. The post describes it as a port to WebAssembly and WebGL; the page runs the PC version of the game. No source code repository has been published; one commenter asked for the files to be put on GitHub.

From the site’s own code we can see a few details:

• game files are fetched in chunks from the site and cached, rather than downloaded all at once (the full data set listed by the site is about 3.6 GB);
• sound is mixed in an AudioWorklet, the browser’s low-latency audio path;
• cutscene videos play in an overlay above the game;
• saves and settings are stored in your browser (IndexedDB).

How to play

1. Open the link above in a new tab. The ?skipmovie part skips the opening videos.
2. Press the start button on the overlay. Browsers only allow sound after a click.
3. Wait while the first assets load. Later areas load as you reach them, so expect short pauses on a slow connection.
4. Play with the keyboard as in the PC version. We have not verified a full key list, so we do not print one here.

Requirements

• A current desktop browser. Chrome or Edge are the safest choice for WebAssembly games.
• Support for cross-origin isolation features (SharedArrayBuffer and Atomics.waitAsync), which current Chromium browsers have.
• A stable internet connection, because the game data is streamed.
• Keyboard; controller support is not documented.

Is it safe and legal?

• It is an unofficial fan project. The Simpsons: Hit & Run was developed by Radical Entertainment and published by Vivendi Universal Games; The Simpsons franchise belongs to Disney. None of them have endorsed this port.
• The game itself is still copyrighted, and the site serves its data. We know of no official digital store that sells it today, so there is no official copy to point to.
• We only link the port’s own site. Nothing is installed on your computer.

Not working?

• “Atomics.waitAsync is not a function” or a filesystem-worker crash: your browser lacks a feature the port needs. Update it or switch to Chrome or Edge.
• Black screen or no sound: click the start button again, and check that the tab is not muted.
• Stutter: close other heavy tabs. A slow connection also causes pauses while new areas load.
• It will not load at all: the site may be down; check back later or try another browser port from our directory.
