What is GitHub?

GitHub is the world's largest software development platform, with over 100 million developers and 300+ million repositories. Owned by Microsoft since 2018, GitHub offers version control, CI/CD, project management and AI-assisted development with GitHub Copilot.

Why GitHub is useful

GitHub is where the developer world comes together:

  • 100M+ developers: The largest developer ecosystem for collaboration and open source
  • GitHub Actions: Powerful CI/CD directly in your repository with a marketplace of 15,000+ actions
  • GitHub Copilot: AI pair programmer that writes code while you think
  • Security: Dependabot, code scanning and secret scanning built in

Time savings with GitHub

GitHub Actions automates your entire development workflow — from code review to production deployment — without external CI/CD tools.

GitHub Actions

CI/CD workflows with YAML. Matrix builds, environments, secrets and a marketplace with thousands of actions.

Pull Requests

Code review with inline comments, suggested changes and automatic checks.

Copilot

AI-powered code suggestions in your editor. Write code faster with context-aware autocomplete.

GitHub Pages

Host static websites for free, directly from your repository with automatic builds.
