BookStack
Self-hosted open-source wiki with books-chapters-pages structure and SAML/LDAP auth
What is BookStack?
BookStack is a free, MIT-licensed, self-hosted wiki organized into a books-chapters-pages hierarchy, with WYSIWYG editing, built-in diagrams.net, full-text search, and enterprise auth (OIDC, SAML2, LDAP). There's no SaaS option, you run it on your own server. Bought (or rather, deployed) by IT teams, homelabbers, and organizations that need a documentation system kept inside their own network.
Markdown-native, local-first, docs, notes, and knowledge tools that are easy for people and AI agents to read.

Use cases to evaluate
Internal IT runbooks and homelab documentation
Departmental knowledge base behind a corporate firewall
School or nonprofit wiki on a single Linux server
Compliance-driven docs that legally must stay on-premise
Fit to evaluate
Sysadmins and IT teams comfortable with PHP/MySQL hosting
Public-sector or healthcare orgs requiring on-prem-only tools
Homelab and small-business users avoiding SaaS subscriptions
Teams wanting LDAP/SAML auth without paying enterprise rates
Business fit
Right for you if you require on-premise hosting for compliance, sovereignty, or budget reasons. Right for you if a simple hierarchical wiki fits how your team thinks. Skip if you don't have anyone willing to maintain a PHP/MySQL stack and run upgrades. Skip if you need rich API docs, real-time collaboration, or AI features, BookStack stays deliberately lean.
How to evaluate BookStack
Use this category when knowledge is scattered across chats, private documents, and tribal memory.
Confirm the exact workflow
Map BookStack to one concrete workflow first, such as internal it runbooks and homelab documentation. Avoid buying before the owner, trigger, output, and success metric are clear.
Check category fit
Compare file portability, linking, search, permissions, and export options.
Compare practical alternatives
Shortlist BookStack against Obsidian, Logseq, Roam Research so the decision is based on fit, effort, and workflow ownership rather than brand recognition alone.
Validate cost and rollout effort
Free and open source (MIT license). Self-hosting cost only: a small VPS or container runs it. No paid tiers, no official hosted SaaS. Also confirm implementation time, support needs, and whether the easy setup matches your team.
