GitHub

GitHub is the world's largest and most influential software development platform — the central nervous system of open-source collaboration and the professional home of the global developer community. Founded in 2008 by Tom Preston-Werner, Chris Wanstrath, PJ Hyett, and Scott Chacon, GitHub transformed Git from a command-line tool into the most widely used collaborative software development platform in history. Acquired by Microsoft in 2018 for $7.5 billion, GitHub today serves over 100 million developers and hosts hundreds of millions of repositories spanning every programming language, framework, and domain of software engineering imaginable. GitHub is the platform where the world's most important software is built. Linux, Python, React, Kubernetes, TensorFlow, and thousands of other foundational open-source projects that power the global technology economy are developed, maintained, and distributed through GitHub. GitHub Actions — the platform's CI/CD automation framework — has become the most widely used continuous integration and deployment system in the industry, enabling developers to automate testing, building, and deployment workflows directly within their repositories. GitHub Packages, Advanced Security, and Codespaces further extend the platform into a comprehensive end-to-end development environment that encompasses the entire software lifecycle from first commit to production deployment. GitHub Copilot — the AI-powered coding assistant built in partnership with OpenAI and trained on billions of lines of public code — represents the next chapter of GitHub's mission: making software development faster, more accessible, and more productive through generative AI integrated directly into the developer's workflow. With enterprise adoption of Copilot accelerating rapidly across the world's largest technology organizations, GitHub is positioned at the center of both the open-source software movement and the AI-powered future of developer productivity. For any organization building software in the modern era — from individual contributors to enterprise engineering organizations of thousands — GitHub is the platform where great code is written, reviewed, and shipped.
