GitHub

GitHub is the de facto standard for source code hosting, collaborative development, and CI/CD pipelines used by over 100 million developers and 4 million organizations worldwide. Built on Git, GitHub adds pull request workflows, code review tooling, issue tracking, project boards, and GitHub Actions — a powerful native CI/CD automation system — on top of the core version control system. GitHub has evolved well beyond a simple Git hosting service into a full software supply chain platform. GitHub Actions enables teams to define complex CI/CD pipelines as YAML workflows that trigger on push, pull request, schedule, or manual dispatch, running on GitHub-hosted runners or custom self-hosted infrastructure. GitHub Packages provides a container and package registry co-located with your code. GitHub Copilot — the AI pair-programmer powered by OpenAI Codex — is deeply integrated into the platform and available as a subscription add-on. GitHub Advanced Security adds secret scanning, code scanning (CodeQL), and dependency review capabilities for enterprise security compliance.
