GitBook is a documentation platform that combines a clean WYSIWYG editor with Git-backed version control. It syncs bidirectionally with GitHub and GitLab, so your docs live alongside your code and stay in sync automatically.
The free Community plan works for public docs with basic features. The Plus plan at $6.70/user/month adds custom domains, advanced permissions, and visitor authentication. Enterprise plans include SSO and priority support.
