This is Stormcloud. It used to be pretty popular. However, it is no longer under active development.
There are two versions here, the desktop version for Ubuntu & Chrome, and the mobile version for Windows Phone 8 & Firefox OS (whoops, both dead platforms). The mobile version is newer, has much better code quality, more settings, and more fancy features. I would recommend using this codebase if you want to either revive Stormcloud, or roll bits of it into your own app.
