GitBook alternatives: 6 apps ranked by verified data

Facts checked Oct 25, 2026AppBreakup editorialHow we rank

Common reasons people leave GitBook: per-site pricing gets expensive with several docs sites, and less suited to a sprawling internal company wiki. We ranked 6 alternatives by how directly each one replaces GitBook, then by reviews, real visits and how recently each app's facts were checked against its own website. Mintlify currently ranks first.
