We host many git repositories on our servers using SSH and file system ACLs for access control. However, having been spoiled by Github for so long, this method feels archaic and cumbersome. While Github provides private repositories, sometimes it’s just not an option because there are some things that may never leave the organization. If you still want to have a fancy web interface for your Git repositories, then there are several alternatives:
Use Github Enterprise.
Use Gitorious.
Use Gitlab.Gitlab is an excellent option. It’s not as fully featured as Github, but like Gitorious it is open source. We’ve found that it’s not only more user friendly than Gitorious but also easier to install.
