GitHub

GitHub is the world’s largest and most widely used platform for software development collaboration. Acquired by Microsoft in 2018, GitHub offers a cloud-based environment where developers can host, manage, and review code using Git version control. It's central to open-source development and is home to millions of repositories from individuals, startups, and major enterprises. GitHub provides powerful features like pull requests, issue tracking, GitHub Actions for CI/CD, and GitHub Copilot—an AI pair programmer powered by OpenAI Codex. It supports collaboration across global teams, enabling developers to contribute to shared codebases securely and efficiently. GitHub also fosters learning and experimentation through features like GitHub Pages and Codespaces. Whether building a hobby project or deploying enterprise software at scale, GitHub remains a vital part of the software engineering ecosystem, driving innovation and transparency in development.
