Git

Git is the version control system. Not a version control system — the version control system. Every tool, every CI/CD pipeline, every hosting platform assumes Git. The mental model of branches, commits, and merges is universal developer knowledge.

The branching model is the real power. Feature branches, pull requests, and rebasing give teams a workflow for parallel development that no centralised VCS ever matched. Combined with GitHub or GitLab for hosting and code review, Git is infrastructure you stop thinking about — it just works.
