Gamebuildr is a time saving and streamlining tool to help game developers with the building pipeline -- mainly compiling and distributing builds. The idea came about when, working on a game, we needed a cloud building tool to save time (as you know, it's a headache to do builds as it ties up a machine and distributing is even worse!) but we couldn't find a solution that worked. Hence Gamebuildr was born.
How Gamebuildr works is fairly simple. You add your code repository, specify your build settings, and Gamebuildr watches your code for changes and builds automatically for you. After pulling in your new changes it will then distribute builds to your team members automatically.
We're currently working on releasing our Unreal Engine supporting beta, so feel free to sign up to be part of the process at http://www.gamebuildr.io/.
