GitHub is a web-based developer platform for version control, code hosting, and software collaboration. Founded in 2008 and acquired by Microsoft in 2018, GitHub is used by individual developers, open-source maintainers, startups, and enterprises to manage repositories, review code, track issues, and automate software workflows.
At its core, GitHub is built around Git, a distributed version control system that helps developers track changes, collaborate in branches, and merge updates. GitHub adds collaboration features such as pull requests, issues, discussions, project boards, and CI/CD automation via GitHub Actions.
