What is GitHub?

GitHub is a complete developer platform that enables millions of developers, businesses, and open source communities to build, scale, and deliver software. It integrates AI-powered tools like GitHub Copilot, CI/CD with GitHub Actions, cloud development environments with Codespaces, and project management with Issues and Projects. The platform supports collaboration, code review, security, and automation across the entire software development lifecycle.
