SparkleShare lets you create your very own version of DropBox. This open source application can be installed into Mac, Linux and Android phones, and used to sync all the files that you have stored on different computers and devices. Just like Dropbox lets you do, really. And since SparkleShare is open source, you can modify the application as much as you want, and have what you’ve made shared with all your friends, and also with all of the rest of the SparkleShare community.
It’s all very simple and straightforward, and a good way to get started is by reading the provided wiki.
This is not the first open source application that emulates the way Dropbox works, though. Linux users have been able to sync and share files between devices for quite some time already by using a service named LipSync.it.
And just in case you’re wondering, work is underway on the Windows and iOS versions of this service. No exact word on when any of these will be released yet, but the SparkleShare team is working on them.
