Git is a distributed version control system[9] that tracks versions of files. It is often used to control source code by programmers who are developing software collaboratively.

Design goals of Git include speed, data integrity, and support for distributed, non-linear workflows — thousands of parallel branches running on different computers.
Git is the de facto standard version control system. It is the most popular distributed version control system, with nearly 95% of developers reporting it as their primary version control system as of 2022. It is the most widely used source-code management tool among professional developers. There are offerings of Git repository services, including GitHub, SourceForge, Bitbucket and GitLab.
