You can now play the original Diablo (and its expansion, Hellfire) in virtually any web browser on any computer with generally excellent performance and operating-as-expected controls. It’s all thanks to an open source project published on GitHub called Diabloweb that’s now being circulated by game developers on X.

In the README file in the project’s GitHub repository, the project’s developer (d07RiV) notes that it is based on DevilutionX, another open source project that did a lot of legwork to make Diablo run well on modern operating systems.

“I’ve modified the code to remove all dependencies and exposed the minimal required interface with JS, allowing the game to be compiled into WebAssembly,” writes d07RiV. “Event handling (especially in the menus) had to be modified significantly to fit the JS model.”
