BookStack vs XWiki

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.

XWiki is a wiki-based collaboration platform for organizing knowledge and supporting shared work. Its editing tools include a WYSIWYG editor, in-place changes, attachments, previews, comments, annotations, notifications, and version history. Teams can also build structured pages and forms with AppWithinMinutes, then browse the resulting information in filterable livetables. The extension library has over 700 ready-to-use options, alongside hundreds of APIs in XWiki’s scripting language. Enterprise features include Active Directory and LDAP connections, single sign-on, office document import or preview, PDF viewing and export, and data imports. XWiki Standard is open source and available free, with cloud and on-premises deployment options. XWiki Cloud covers setup, hosting, upgrades, maintenance, backups, security updates, and 24/7 monitoring. The free Community plan is on-premises with community support and no guarantees. The pricing note lists paid service from €1/user/mo and a 30-day trial; the homepage says the trial can be extended on request and requires no credit card.
