Tool · [Standard tools and platforms](https://ecosystem.samcarlton.com/tools)

Also called: git-scm, Git version control

The free, [open source](https://ecosystem.samcarlton.com/open-source) [version control](https://ecosystem.samcarlton.com/version-control) program that almost every software team uses. It keeps the full history of a project in a [repository](https://ecosystem.samcarlton.com/repository) on each [developer](https://ecosystem.samcarlton.com/software-engineer)'s computer, records each change as a [commit](https://ecosystem.samcarlton.com/commit), and lets people work on branches and combine them later. [GitHub](https://ecosystem.samcarlton.com/github), [GitLab](https://ecosystem.samcarlton.com/gitlab) and [Bitbucket](https://ecosystem.samcarlton.com/bitbucket) are websites built around Git.

**For example:** A [founder](https://ecosystem.samcarlton.com/founder) hears "it's all in Git" and asks where the [repository](https://ecosystem.samcarlton.com/repository) is [hosted](https://ecosystem.samcarlton.com/hosting). The answer is [GitHub](https://ecosystem.samcarlton.com/github), which stores the Git history online.
