SparkleShare is a free and open-source cloud storage and file synchronization software. By default SparkleShare uses Git as a storage backend and creates a special folder on your computer that you can add remotely hosted folders (directories). Projects in this folder will automatically stay synced with the host and its peers. When someone add, remove or edit files within a project, syncronization happens across peers. SparkleShare can be used with hosted services such as GitHub, but can also be hosted on your own server for more control.
