GitHub ( passed 100 million repositories in November, but that number “could be set to explode as the code-hosting platform today announced that it’s opening up private repositories to free users for the first time,” according toVentureBeat (

GitHub is a development platform in which you can host and review code, management projects, and build software alongside 31 million developers. The company says it’s used by more than 2.1 million business and organizations. 

Git is a version-control system for tracking changes in computer files and coordinating work on those files among multiple people. It’s mainly used for source-code management in software development; however, t can be used to keep track of changes in any set of files.

GitHub currently offers a number of paid plans, each of which offer unlimited public and private repositories where users’ project files and revision history are stored. It’s previously been free only for use on public repositories and open-source projects. However, as VentureBeat notes, moving forward non-paying users can access unlimited private repositories, albeit with an upper restriction of three collaborators.
