Nextcloud is essentially a framework for apps. The strict separation between file access (WebDAV) and management (OCS API) gives us clean integration points for any requirement.
WebDAV for performant file operations (upload, download, sync), OCS API for managing users, groups, and shares. Ideal for using Nextcloud as a headless file server for your customer portal or intranet - without end users seeing the Nextcloud interface.
The Flow Engine captures events as they happen: file uploaded, tag set, share created. This allows us to forward documents directly after upload to third-party systems (OCR server, archive systems, DMS) - without touching the core code.
We develop custom apps based on PHP (backend) and Vue.js (frontend). These integrate seamlessly into the interface (Files, Talk, Groupware) and appear to end users as native components - update-safe through the official API.
How we implement Nextcloud development in practice.
Incoming documents (invoices, contracts, applications) must be manually sorted, converted, and forwarded to the right place.
Flow-based automation recognizes document types (via OCR/AI), converts to PDF/A, adds watermarks, and moves to the correct folder structure. Notifications automatically go to responsible persons.
Customers should be able to view documents stored in Nextcloud - but without direct access to the backend or Nextcloud UI.
We develop a lean React frontend that retrieves documents via OCS/WebDAV API and displays them in your customer's branding. Authentication runs through your existing SSO (Keycloak, Authentik). Secure, isolated, update-independent.
Standard LDAP integration maps groups 1:1. More complex requirements (nested groups, dynamic assignments, role-based permissions) are not covered.
A custom auth service (Python/Node.js) sits between LDAP and Nextcloud. It transforms group memberships according to your rules, synchronizes quota settings, and sets permissions automatically - on every login or via cronjob.

“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”

“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.”

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

The team not only implemented our requirements but also thought along and proactively.
