GitHub

GitHub

AI-suggested

GitHub is the world's largest platform for hosting Git repositories, combining version control with code review, issue tracking, and CI/CD through GitHub Actions. It is the default home for the vast majority of open-source projects and a standard tool at software companies of every size. Pull requests are the core collaboration unit, providing inline code review, required status checks, and merge queues that keep the main branch stable. GitHub Actions extends this into full CI/CD pipelines defined directly alongside the code in YAML workflows. GitHub Copilot, built into the editor and now the platform itself, brings AI code completion and chat-based assistance directly into the development workflow, while GitHub Advanced Security adds automated vulnerability and secret scanning.
