Definition
GitHub is the world's largest code hosting platform built around Git, offering repository hosting, collaboration tools, CI/CD, and package registries for software teams.
Overview
GitHub took the distributed version control system Git and wrapped it in a social, web-based platform: pull requests for reviewing changes, issues for tracking work, and a public profile and contribution graph that made open-source collaboration visible and discoverable in a way that raw Git tooling never was on its own. Beyond hosting repositories, GitHub has grown into a full software delivery platform. GitHub Actions provides built-in CI/CD directly wired to repository events, GitHub Packages hosts container and language package registries, and GitHub Codespaces offers cloud development environments. Security features like Dependabot and code scanning are built into the same workflow developers already use for code review. Microsoft acquired GitHub in 2018 and has continued to expand the platform since, notably integrating AI through GitHub Copilot for code suggestions directly in the editor. GitHub competes with platforms like GitLab and Bitbucket, which offer similar Git hosting and CI/CD feature sets under different pricing and deployment models. The SkillVeris guide Git and GitHub for Beginners: The Complete Guide walks through the fundamentals covered here in more depth.
