GitBook
Documentation sites that stay in sync with your repository

GitBook publishes product documentation as a branded site, written in a block-based visual editor rather than by hand-rolling a static site generator. Content syncs both ways with GitHub or GitLab, so writers can work in the editor while engineers edit markdown in the repo and neither overwrites the other, and pull requests get preview deployments of the docs they change. API reference pages are generated from an OpenAPI spec with interactive playgrounds that let a reader send a request from the page. Paid plans add a custom domain, deeper branding, AI search, analytics and reader feedback; the top tier adds an AI assistant that answers from your docs and reports on what it was asked. Pages are optimised for language models as well as readers. Pricing is per published site plus a per-user fee for the team editing it.

What people are saying about GitBook
50% neutral“I wouldn’t say GitBook is the same feature set though. Their editor is better for non technical people, but the Git workflow, drift checks, llms.txt and MCP support are the reasons we stayed with Mintlify. The pricing jump is still a fair criticism.”
“did you explore other options like gitbooks?”
“I use it for reviewing this massive GitBook site I’m making for technical reference documentation on the most involved roles in cybersecurity; like HackTricks for everything from Pen Testing to DFIR and Malware Analysis/Development.”
