Reviewers mostly see GitHub as the default home for code: strong on version control, pull requests, issue tracking, open-source collaboration, and keeping teams organized. GitHub Actions comes up often as a real strength for automating tests, builds, releases, and deployments, though some say Actions can be slow, costly at scale, or hard for beginners. Several users also mention a steep learning curve, complex settings, weak support, and concerns that newer AI features add confusion, privacy questions, or occasional slowdowns.
