SparkleShare
Share and collaborate by syncing with any Git repository
SparkleShare creates a special folder on your computer. You can add remotely hosted folders (or "projects") to this folder. These projects will be automatically kept in sync with both the host and all of your peers when someone adds, removes or edits a file. SparkleShare was made to cover certain use cases, but doesn't handle every scenario well. SparkleShare uses the version control system Git under the hood, so setting up a host yourself is relatively easy. Using your own host gives you more privacy and control, as well as lots of cheap storage space and higher transfer speeds. The idea of SparkleShare sprouted at the GNOME Usability Hackfest in London, where a couple of designers came to the conclusion that they didn't have a good (Open Source) collaboration tool to share their work. -
