BrowserQuest is a massively multiplayer adventure game created by Little Workshop (@glecollinet & @whatthefranck) and Mozilla.

BrowserQuest is a tribute to classic video-games with a multiplayer twist. You play as a young warrior driven by the thrill of adventure. No princess to save here, just a dangerous world filled with treasures to discover. And it’s all done in glorious HTML5 and JavaScript.

Even better, it’s open-source so be sure to check out the source code on GitHub. (some folks, including our friends at CERN, have forked the game. Check out ParticleQuest!)

Jster has an amazing collection of open libraries and tools that you can use to start building your game.


BananaBread is a 3D first person shooter that runs on the web. It takes the Cube 2: Sauerbraten engine, which is written in C++ and OpenGL, and compiles it using Emscripten into JavaScript and WebGL so that it can run in modern browsers using standards-based web APIs and without the need for plugins.

The project has several goals. First, to serve as a testcase for running a demanding 3D game in browsers: Having a working testcase lets us try out new browser features and to profile performance in order to make browsers faster. Another goal is to prove that games of this nature can run in JavaScript and WebGL, which many people are skeptical about. Finally, all the code in this project is open (and practically all the art assets), so others can learn from this effort and use this code to create their own browser games.
