gita is a command line tool to manage multiple git repositories in parallel. You can easily check the status of several repositories, pull, push, commit, and so on.
This is a nice alternative to how we are handling things at work, with hundreds of repositories all around, but with a lot of overlap between them too. For us, a custom set of scripts works pretty well, with a combination of a powerful terminal emulator. Terminator, for example, provides handy functionality of split screen view, with grouped terminals, where multiple screens can be easily updated with a single command input.
