GitBook
Documentation platform for product and API docs, synced with Git
What is GitBook?
GitBook is a platform for writing and publishing product documentation, API references and help centers. Teams edit in a block-based editor or sync content with GitHub or GitLab, then publish it as a hosted docs site. Paid plans are priced per published site plus a fee per user, and add AI search, an AI assistant for readers and an agent that flags and updates outdated content.
GitBook has a free plan. Paid plans start at $65 per site / month, billed annually, plus $12 per user / month. See every plan
Good for
- Public product and API documentation for software companies
- Teams that want docs reviewed and merged in a Git workflow
- Open source projects, which can apply for the free Community plan
Worth knowing
- Paid plans combine a per-site fee with $12 per user / month, and guests and read-only members cost the same as other members.
- The pricing page shows annual-billing prices and advertises 2 months free; month-to-month rates are not shown in its default view.
- The Free plan covers a single user and leaves out custom domains, AI search and AI writing.
- SAML SSO is limited to Enterprise; the AI Assistant, adaptive content and authenticated access need Ultimate at $249 per site / month.
