WZ-IT runs Wiki.js as a dedicated instance in data centres in Germany, Switzerland or Austria, with updates, daily backups, 24/7 monitoring and a personal contact. On request, we also install Wiki.js in your cloud or on premises.
Wiki.js is extensible open-source wiki software with visual and Markdown editing, search and granular permissions. The project is released under the AGPL-v3 licence.
Wiki.js is based on Node.js and supports different databases as well as external search and storage targets. The architecture is selected for user volume, content size, integrations and availability requirements.
Works on virtually any platform and is compatible with PostgreSQL, MySQL, MariaDB, MS SQL Server or SQLite.
Comprehensive Administration
Manage all aspects of your wiki using the extensive and intuitive admin area.
Node.js-based Application
Wiki.js is based on Node.js. Actual performance depends on the database, search, storage, caching and selected infrastructure.
Fully Customizable
Fully customize the appearance of your wiki, including light and dark mode.
Flexible Access Rights
Make your wiki public, completely private or a mix of both with granular permissions.
Scalable
Wiki.js intelligently makes use of available resources - from Raspberry Pi to high-performance VM in the cloud.
Easy Installation
Installation guides are available for supported platforms. Production effort also depends on database, identity, networking, backups and migration scope.

Modern Editor
Visual editor with Markdown support, code highlighting and integrated diagramming tools for structured documentation.
Infrastructure, integration and operations
Wiki.js as part of your infrastructure
We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.
Architecture and migration
Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.
On-Premise
In your data center: Installation on bare-metal, VM or Docker · Integration with existing Active Directory/LDAP
Installation in your cloud
In your own cloud account, for example with AWS, Azure, GCP or Hetzner · Terraform/IaC setup (optional) · Kubernetes or Docker Compose · Capacity and scaling design
Enterprise Setup
Advanced architecture after technical and licence assessment: HA and recovery design where supported by the application and edition · Logging according to feature set and edition · Custom security policies
Network and identity
SSO, secure access, internal systems and existing security components are integrated appropriately.
VPN Access
WireGuard, NetBird, Tailscale, Headscale, OpenVPN, Cloudflare Tunnel · Easy client setup for all devices
SSO Integration
Directly or through an upstream identity layer
Multi-Factor Auth
Depends on application, edition and identity provider
Firewall & Hardening
Fail2Ban, Rate Limiting, IP Whitelisting
Monitoring and service level
Updates, backups, technical monitoring and response paths follow a transparent operational scope.
24/7 proactive monitoring
Updates and patches
Regular updates, CVE monitoring and prioritised patches for critical vulnerabilities
Daily backup with 7-day retention
Personal technical contact
Integration and development
APIs, automation and custom extensions can be delivered beyond basic deployment.
GraphQL API Access
Wiki.js is API-first. We use the GraphQL API to display content and create it programmatically - e.g., automatic documentation from code comments.
Git-Sync Automation
Docs-as-Code. We configure Git sync so changes in the repo immediately land in the wiki - and vice versa. Including review workflows via pull requests.
Custom Rendering Modules
Standard Markdown not enough? We develop rendering modules for specific data types: CAD files, interactive schematics, or Swagger UI embeddings.

Concrete Use Cases
Wiki.js Development & Integration
Wiki.js stands out with its modern architecture (Node/GraphQL). We extend this base to seamlessly integrate documentation into technical workflows.
Proprietary Authentication
Problem
Login must occur via an internal legacy IDP that does not speak standard OIDC/SAML.
Solution
Development of a custom Passport.js strategy for Wiki.js that performs authentication against your proprietary system.
Auto-Generated API Docs
Problem
API documentation in the wiki is always outdated because developers have to maintain it manually.
Solution
CI/CD pipeline that generates OpenAPI/Swagger files during build and pushes them to the wiki via GraphQL. Always in sync with code.
Interactive Graphs
Problem
Complex relationships between articles (e.g., IT infrastructure) are hard to understand in text form.
Solution
Embedding a graph visualization module (Mermaid/D3.js) that automatically represents links between pages as an interactive network map.

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, privacy-focused, and with control over data location and access.
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.
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.

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). Both are open source and self-hostable. We advise on which solution fits your requirements.
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
