GitHub

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.

Hidden features that often go unused

GitHub offers much more than just code hosting:

• Codespaces: Cloud-based development environments that start in seconds.
• GitHub Projects: Project management with views, custom fields and automation.
• Discussions: Community forums directly in your repository for questions and ideas.
• GitHub Packages: Host npm, Docker, Maven and NuGet packages alongside your code.
• Branch Protection: Require reviews, CI checks and signed commits for main branches.
• Code Search: Search across 100M+ repositories with regex and symbol-level search.

Integrations with other tools

GitHub integrates with many other tools and services:

• AWS, Azure & Google Cloud: Native deployment from GitHub Actions.
• Jira & Slack: Integrations for project tracking and notifications.
• VS Code: GitHub Copilot and Codespaces directly in your editor.
