Overview

Git is a free and open source distributed version control system designed to handle projects of any size with speed and efficiency. Originally built to manage the Linux kernel's massive codebase, Git has become the industry standard for version control, with 96% of professional developers using it according to the 2022 Stack Overflow survey.

The core Git project is a command-line tool, but it has spawned a massive ecosystem of hosting services (GitHub, GitLab), graphical interfaces, editor integrations, and developer tools. Git stores repository history efficiently—the entire Linux kernel history of 1.4 million commits takes only 5.5 GB of storage.

Git is released under the GNU General Public License v2.0, guaranteeing freedom to share and modify the software while protecting the Git trademark from misuse.
