GitHub

A web platform for hosting code, collaborating and automating software delivery, with built-in AI via Copilot.

About GitHub

GitHub is a developer platform where teams host source code, plan work, review changes and ship software in one place. It is aimed at individual developers, open source communities, start-ups and large enterprises.

The platform brings together code hosting, issues, discussions and project planning alongside the code itself. Code review can be shared among teammates, and initial reviews can be assigned to GitHub Copilot.

GitHub Copilot is the AI assistant, offering chat, an agent mode and a desktop app. GitHub Actions handles CI/CD automation, and GitHub Codespaces provides cloud-based development environments.

Security tools include GitHub Advanced Security, Copilot Autofix, Dependabot and secret protection. GitHub Marketplace lets users extend their toolchain with apps, actions and AI models.
