A self-hosted wiki lets you manage content on your own server, giving you full control over your data and setup. Two of the most popular options are DokuWiki and Wiki.js. Both are free and open source, but they work in different ways. DokuWiki stands out for its simplicity and ease of use, while Wiki.js provides a modern interface with advanced collaboration features. In this guide, we’ll compare both to help you decide which one best aligns with your needs.
DokuWiki is Ideal For Small Teams and Personal Projects
DokuWiki is a lightweight, open-source wiki software built with PHP. It stores content in plain text files, making it easy to set up on any basic server without needing a database. Its low server requirements and simple installation process make it ideal for small teams and personal projects.
DokuWiki includes a built-in version control system to track changes, compare edits, and prevent conflicts. Access permissions can be managed at both page and section levels, with support for LDAP and Active Directory, making it suitable for larger organizations as well.
DokuWiki also supports thousands of plugins for customization, though some are outdated and may not work with the latest versions. Its interface can feel old-fashioned, and it lacks real-time collaboration since only one user can edit a page at a time. Features like tagging and privacy controls are available, but are limited compared to other modern platforms.
Wiki.js Allows Multiple Users to Collaborate Simultaneously
Wiki.js is a modern, open-source wiki platform that offers a user-friendly interface for both desktop and mobile devices. It supports real-time editing using Markdown, allowing multiple users to collaborate simultaneously, similar to Google Docs.
It integrates with various authentication providers like Google, GitHub, LDAP, and Discord. Git integration enables automatic backups, version tracking, and easy content restoration. Wiki.js also comes with built-in tools for search, media management, and image previews, reducing the need for external plugins.
However, Wiki.js requires a SQL database and Node.js, which can make the setup more complex and resource-intensive. It may not be ideal for basic hosting environments, and some users find its navigation less intuitive.

Security Comparison
DokuWiki offers built-in authentication and supports LDAP/Active Directory via plugins. Access control is managed through ACLs, making it effective for multi-user setups. Maintaining security involves regular PHP/plugin updates, using HTTPS, and setting proper file permissions.
Wiki.js supports advanced security options, including 2FA, OAuth, SAML, and integrations with Google and GitHub. Its RBAC system enables detailed control over user roles and permissions. Security best practices include keeping Node.js and the database updated, using environment variables for secrets, and enabling Git-based versioning for backup and recovery.
Cost Considerations While Choosing a Self-hosted Wiki
DokuWiki is ideal for low-cost setups. It runs without a database and works well on shared hosting or lightweight VPS plans.
Wiki.js requires more resources, including Node.js and a SQL database. A VPS or cloud server is recommended, and additional costs may arise if using Docker or managed cloud databases.
Which Wiki Is Right for You?
Here’s a detailed side-by-side comparison of DokuWiki and Wiki.js that highlights their core features, strengths, and ideal use cases:
| Feature | DokuWiki | Wiki.js |
|---|---|---|
| Technology Stack | PHP-based, stores data in plain text, no database required | Node.js-based, requires a SQL database (e.g., PostgreSQL, MySQL). |
| Ease of Setup | Easy to install on any PHP-supported server. | Requires Node.js and a database, but Docker and guides simplify setup. |
| Editing Experience | It uses its own wiki markup syntax. A visual editor is available through plugins. | Supports Markdown, WYSIWYG, live preview, and HTML |
| Authentication | Includes a basic user manager and supports LDAP or Active Directory through plugins. | Built-in support for Google, GitHub, LDAP, SAML, OAuth, and 2FA. |
| Access Control (ACL) | It allows page/section-based permissions using ACL. | It provides detailed access control with roles, groups, and permissions for fine-grained control. |
| Search Functionality | It has a built-in full-text search engine. | Wiki.js includes full-text search with external integrations like Elasticsearch, Algolia |
| Plugins / Extensions | It offers over 1,000 plugins that allow you to add features like SEO tools, diagrams, and export options. | It has a modular system with built-in tools; fewer plugins than DokuWiki. |
| User Interface | Simple and functional; themes are available, but may look outdated. | Modern, responsive UI with dark/light mode and mobile support. |
| Backup & Portability | Easy file-based backup by copying folders. | Supports Git sync, database backups, and external storage (e.g., S3, Dropbox). |
| Performance | Lightweight and runs well on low-resource servers. | Needs more resources; better suited for dedicated or cloud servers. |
| Best Use Case | Suitable for personal wikis, schools, and small teams. | Ideal for modern teams needing real-time editing and integrations. |
Both these self-hosted platforms have their own strengths. DokuWiki is a great choice if you want a simple, database-free solution that’s easy to set up and maintain. Its lightweight nature makes it ideal for personal wikis, internal documentation, or small teams working in low-resource environments.
On the other hand, Wiki.js is better suited for modern teams that need real-time collaboration, third-party integrations, and fine-grained access control. While it requires more setup and resources, it offers a sleek interface and powerful features for growing or enterprise-level projects.
