List of JS game engines. You can find a wikified version at Feel free to modify that. I sync it here every once in a while.

IMPORTANT! Remember to check out the wiki page at for the most up to date version. There's also a "notes" column in the table but it simply does not fit there... Check out the raw version to see it.

This table contains primarily HTML5 based game engines and frameworks. You might also want to check out the [[Feature Matrix|Game-Engine-Feature-Matrix]], [[Game Resources]] and [[Scene Graphs]].

It might be a good idea to create a separate category for engines dedicated or supporting deployment to mobile devices (iOS, Android, Blachberry, WinPhone etc.)

Game Closure provides a DevKit. It's a staged JavaScript development environment for building web, iOS, and Android games. It has a set of browser-based tools and a fully-documented SDK. And remote debugging and a test app for mobile devices.


License: Free to use and modify. A splash screen is required for games built with the devkit.

This list would be much more interesting if it included links to games done with each engine.
