GitHub, owned by Microsoft since 2018, is the dominant platform for software development collaboration. It hosts over 420 million repositories and is used by the majority of open source projects globally, as well as enterprises running private codebases.
At its core, GitHub provides Git-based version control with a web interface for code review via pull requests, issue tracking, project boards, and wikis. GitHub Actions enables CI/CD pipelines directly within the platform without third-party tools.
GitHub Copilot has become a significant product. The AI coding assistant integrates with VS Code and JetBrains, providing inline code suggestions, chat assistance, and automated code review. GitHub is moving to usage-based billing for Copilot at the enterprise tier as of June 2026.
The free plan is genuinely useful with unlimited public and private repositories and Copilot Free for individuals. Team at $4/user/month adds more Actions minutes and protected branches. Enterprise at $21/user/month adds SAML SSO, audit logs, and advanced security.
GitHub is the default choice for software development teams of any size. GitLab is the main alternative for teams wanting a self-hosted option or tighter CI/CD.
