Git is a distributed version control system that tracks changes in source code during software development, enabling multiple developers to work on projects simultaneously without conflicts. GitHub is a cloud-based platform built on Git that adds collaboration features like pull requests, issue tracking, merge queues, and continuous integration. Together, they form the backbone of modern software development workflows — Git handles the local version control while GitHub facilitates team collaboration, code review, and project management at scale. As of Git 2.54 (2026), the toolset continues to evolve with improved sparse-checkout, background maintenance, and history-editing capabilities.
