Alternatives to BookStack
Self-hosted docs organized as books
BookStack ranks #4 of 9 in Team wikis, with an Alt Score of 89. It is licensed under MIT, free and available on the web. 11 of 12 checklist rows are verified against a public source.
Teams and individuals who need a lightweight, self-hosted place to organize documentation and internal knowledge, especially organizations that want to keep control of their data rather than use a hosted wiki.
A free, open-source wiki platform with a WYSIWYG editor (Markdown supported) for writing pages, built-in search, and integrated diagrams.net for visuals. It includes role-based permissions, page revision history, multi-factor and SSO authentication (LDAP, SAML2, OIDC, social login), and light/dark themes.
Content is organized in a hierarchy of shelves, books, chapters, and pages, mirroring how physical reference material is structured. Users create pages within books (optionally grouped into chapters), and shelves group related books together; any paragraph can be linked to directly for cross-referencing.
