Wiki.js vs BookStack: Which Self-Hosted Wiki?
Quick Verdict
BookStack is the better choice for most teams. Its book/chapter/page structure is intuitive, setup is simpler, and the WYSIWYG editor works well for non-technical users. Wiki.js wins on flexibility — it supports multiple editors (Markdown, WYSIWYG, HTML), has built-in Git sync, and handles larger-scale deployments better. Pick BookStack for ease of use, Wiki.js for power and flexibility.
Overview
Both Wiki.js and BookStack are self-hosted wiki platforms designed for team documentation. They solve the same problem — organizing knowledge in a searchable, collaborative format — but take different approaches.
BookStack organizes content as Books → Chapters → Pages. Think of it like a digital bookshelf. It’s built with Laravel (PHP) and uses MySQL/MariaDB. Created by Dan Brown, it’s been actively developed since 2015. BookStack site
Wiki.js takes a more traditional wiki approach with a flat page structure organized by paths. Built with Node.js, it supports PostgreSQL and multiple editor types. Created by Nicolas Giard, the current v2.5 is stable while v3.0 is in development. Wiki.js site
Feature Comparison
| Feature | Wiki.js | BookStack |
|---|---|---|
| Content structure | Flat pages with path hierarchy | Books → Chapters → Pages |
| WYSIWYG editor | Yes | Yes (default) |
| Markdown editor | Yes | Yes (alternative) |
| HTML editor | Yes | No |
| Editor choice | Per-page (cannot change after creation) | Global toggle |
| Search | Full-text (PostgreSQL) | Full-text (MySQL/MariaDB) |
| Git sync | Built-in bidirectional | No (manual export only) |
| Authentication | Local, LDAP, OIDC, OAuth2, SAML, 2FA | Local, LDAP, OIDC, SAML, social login |
| Permissions | Path-based rules | Role-based per book/chapter/page |
| API | GraphQL | REST |
| Diagrams | draw.io integration | draw.io integration |
| Image manager | Yes | Yes |
| Revision history | Yes | Yes |
| Comments | Yes (per page) | Yes (per page) |
| Export | Markdown, HTML, PDF | PDF, HTML, Markdown, plaintext |
| Themes | Dark/light + customizable | Customizable (CSS) |
| Multilingual | 40+ languages | 40+ languages |
| Database | PostgreSQL | MySQL/MariaDB |
| Runtime | Node.js | PHP (Laravel) |
| Docker image | ghcr.io/requarks/wiki:2.5 | lscr.io/linuxserver/bookstack |
| License | AGPL-3.0 | MIT |
Installation Complexity
BookStack is easier to set up. The LinuxServer.io Docker image handles most configuration through environment variables. You need MariaDB and a few env vars (APP_URL, DB_*, APP_KEY) and you’re running.
Wiki.js requires PostgreSQL and fewer initial env vars, but the post-install admin setup has more options to configure. The Git sync feature requires additional setup if you want it. Editor type is set per-page and cannot be changed after page creation — this catches people off guard.
Performance and Resource Usage
| Metric | Wiki.js | BookStack |
|---|---|---|
| RAM (idle) | ~150-200 MB | ~100-150 MB |
| RAM (active) | ~300-500 MB | ~200-300 MB |
| CPU | Moderate (Node.js) | Low (PHP) |
| Disk | ~500 MB (app) | ~300 MB (app) |
| Database | PostgreSQL | MySQL/MariaDB |
| Page load speed | Fast (SPA-like navigation) | Fast (traditional server-rendered) |
BookStack is lighter on resources. Wiki.js has a more modern frontend that feels faster during navigation but uses more memory.
Community and Support
Wiki.js has 25,000+ GitHub stars, an active Discord community, and a dedicated documentation site. Development on v2.x has slowed as the creator focuses on v3.0 (complete rewrite). Bug fixes still land, but new features are rare.
BookStack has 16,000+ GitHub stars, active GitHub discussions, and excellent documentation. Dan Brown maintains it actively with regular releases. The update cadence is faster than Wiki.js — monthly releases are common.
Use Cases
Choose Wiki.js If…
- You want Git-backed documentation (version control with your code)
- Your team uses different editors (some prefer Markdown, others WYSIWYG)
- You need GraphQL API access
- You want SAML SSO with advanced group mapping
- You’re documenting a software project and want docs alongside code
Choose BookStack If…
- Your team includes non-technical users who need a simple interface
- You want an intuitive content hierarchy (books/chapters)
- You need granular per-book or per-chapter permissions
- You want the simplest possible setup and maintenance
- You’re replacing Confluence and want something immediately familiar
Final Verdict
BookStack for most teams. The book/chapter/page structure maps well to how people think about documentation. Setup is simpler, resource usage is lower, and updates come regularly. Non-technical team members can start contributing immediately.
Wiki.js for developer teams. If Git sync matters, if you want Markdown-first docs, or if you need advanced authentication integrations, Wiki.js is the more powerful tool. Be aware that v2.x development has slowed — v3.0 is coming but has no release date.
FAQ
Can I migrate from Wiki.js to BookStack or vice versa?
There’s no direct migration tool. Both support Markdown export, so you can export from one and manually import into the other. For large wikis, community scripts exist but expect some manual cleanup.
Which is better for replacing Confluence?
BookStack. Its book/chapter/page hierarchy is the closest equivalent to Confluence’s spaces/pages model. Non-technical users will adapt faster. See Self-Hosted Alternatives to Confluence.
Does Wiki.js v3 change the comparison?
Wiki.js v3 is a complete rewrite with new features (real-time collaboration, new editor). It’s not released yet and has no firm date. When it ships, this comparison will be updated. For now, compare based on what’s available today: v2.5.
Which has better search?
Both have good full-text search powered by their respective databases. Wiki.js supports additional search engines (Elasticsearch, PostgreSQL full-text) for very large wikis. BookStack’s search works well up to thousands of pages without extra configuration.
