Everything you need to know about Wiki.js
Wiki.js is a modern, open-source wiki engine based on Node.js. It allows you to create content in Markdown or via a visual editor and organizes knowledge bases, documentation, or internal wikis in a structured and clear manner.
Wiki.js combines several advantages: fast, performant execution thanks to Node.js, flexible storage options (including Markdown + Git backend instead of database lock-in), modern interface, visual and Markdown editing, version control, search function, and granular access rights — ideal for teams, companies, or government agencies.
Wiki.js is platform-independent — you can run it on VM, bare-metal server, Docker, or cloud VM. Supported databases include PostgreSQL, MySQL, MariaDB, SQLite, MS SQL, etc.
Yes — Wiki.js can be deployed in the cloud, on VMs, or as an on-premise installation. With our managed service, we install and configure Wiki.js on your infrastructure — locally in your data center, GDPR-compliant, and with full control over your data.
You can edit content using Markdown or use the visual editor — ideal for both developers and non-technical users. Multimedia (images, videos, documents) can be easily embedded.
Wiki.js stores content as Markdown files, and through Git integration, changes can be versioned, tracked, and reverted if needed. This provides security and transparency — ideal for enterprise wikis and documentation.
Yes — Wiki.js has a fine-grained role and rights management: you can precisely control who can view, edit, or administer content. This makes the system suitable for internal company wikis with confidential information.
Yes — Wiki.js supports multilingualism and can be configured as a multilingual wiki. This makes it suitable for international teams or globally operating companies.
Wiki.js is ready to use in just a few clicks. The platform is designed to be intuitive and requires no technical expertise for daily use.
Yes — Wiki.js is performant and scalable. Thanks to the Node.js engine, efficient caching, and support for lightweight or powerful infrastructure, the wiki can keep up with growing demands.
We offer complete installation and configuration, hosting on your infrastructure or in certified data centers, backup & versioning, security hardening, monitoring, and optional managed service for operation, updates, and support.
For companies of all sizes — from small teams to enterprise — who want central knowledge management, documentation, internal manuals, or collaborative document work. Especially suitable when data protection, control, version history, or rights management are important.
Yes — Wiki.js supports various authentication options (e.g., LDAP, OAuth), can be integrated into existing infrastructures, and is suitable for complex environments with multiple applications and services.
Through Git backend, version control, and regular backups, data and documents can be securely restored. With managed hosting or professional maintenance, we ensure your wiki runs reliably and stably.
Unlike cloud wikis, with Wiki.js you retain full control over data, hosting, and infrastructure — ideal for data protection, compliance, GDPR. Additionally, expensive ongoing license or usage fees are eliminated.
There are several self-hosted wiki platforms: Docmost is a modern collaboration platform with real-time features. BookStack uses a simple hierarchical structure (Books/Chapters/Pages) and is particularly user-friendly. Both are open source and self-hostable. We're happy to advise you on which solution best fits your requirements.

"I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us."
Data Manager, ARGE, Germany

The collaboration is uncomplicated, reliable and always on an equal footing. That makes IT fun - and above all: it works! Big thank you to the team! (translated) "

CEO, Odiseo Solutions, Spain
"Counting on WZ-IT team was crucial, their expertise and solutions gave us the pace to deploy in production our services, even suggesting and performing improvements over our configuration and setup. We expect to keep counting on them for continuous maintenance of our services and implementation of new solutions."
Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)
We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)
Robin and Timo provided excellent support during our migration from AWS to Hetzner! We received truly competent advice and will gladly return to their services in the future. (translated)
WZ-IT set up our Jitsi Meet Server anew - professional, fast, and reliable. (translated)
Whether a specific IT challenge or just an idea – we look forward to the exchange. In a brief conversation, we'll evaluate together if and how your project fits with WZ-IT.
