 It's both a startup and a community project, completely open source under the [MIT and Creative Commons licenses](http://codecombat.com/legal). It's the largest open source [CoffeeScript](http://coffeescript.org/) project by lines of code, and since it's a game (with [really cool tech](https://github.com/codecombat/codecombat/wiki/Third-party-software-and-services)), it's really fun to hack on. Join us in teaching the world to code! Your contribution will go on to show millions of players how cool programming can be.
