GitHub UI design & app screens

GitHub is the platform developers use to host code, review pull requests, track issues, and collaborate on software. It's central to open-source and professional software development.

The interface is a reference for developer tooling design: repository views, diff and code review experiences, issue and project boards, and Actions for CI/CD. Designers study its file browser, syntax-highlighted diffs, PR conversation threads, and the Primer design system that keeps a deeply technical product consistent and accessible across light and dark modes.
