Git

Git revolutionized software collaboration, becoming the invisible backbone used by over 100 million developers globally. Created by Linus Torvalds, it is faster than the average version control system, enabling distributed workflows that power GitHub and GitLab. Compared to the Linux Kernel at #1, Git is more narrowly focused but equally transformative, as it processes merge operations in milliseconds and handles repositories with millions of commits—a concrete metric that underscores its efficiency.
