In their own words
BookStack
BookStack is a free, open-source platform for organizing and storing information on a self-hosted instance. It organizes content into Books, Chapters and Pages, with a WYSIWYG editor and an optional Markdown editor with live preview. Search works within a book or across books, chapters and pages, and users can link directly to paragraphs. The editor includes diagrams.net drawing capability. Authentication supports OIDC, SAML2 and LDAP, as well as social-based secondary authentication options. Built-in multi-factor authentication can be enforced by role and uses TOTP and static backup codes. Content exports include contained HTML, PDF, plain text, Markdown and Portable ZIP. The project describes a growing REST API for automation and importing content. The MIT-licensed software has no cost to download and install. Setup requires PHP 8.2 or newer, MySQL 8.0 or MariaDB 10.6 or newer, Git, Composer 2.2 or newer and a PHP-compatible web server. BookStack does not currently support shared PHP hosting. Community support is free but does not assure a response, support or resolution; paid support plans are also listed.
