WZ-IT runs Open WebUI as a managed service and AI platform: your own instance on your own domain, models operated in Germany by German providers, without US clouds, SSO, DPA and a Section 203 supplementary agreement from the smallest package. On request the platform runs only in your network or on premises.
Customers from mid-sized business, industry and the public sector, in Germany and internationally
About the technology
Open WebUI is an extensible, self-hosted AI interface for Ollama and OpenAI-compatible APIs. It brings models, chats, knowledge sources and tools into one interface and can run locally, in the cloud or as part of a hybrid architecture.
At WZ-IT, Open WebUI runs as a managed AI platform: instance, models, knowledge bases, SSO and operations come from one provider, with a DPA and a Section 203 supplementary agreement.
Licence
WZ-IT operates Open WebUI under the Open WebUI License with the original branding unchanged. No branding modification is made. On request, we support you in obtaining any required vendor licence.
Use Cases
WZ-IT AI platform
Open WebUI ships without models. The AI platform provides both: a dedicated instance, models operated in Germany by German providers without US clouds and without training on your inputs, a DPA and a Section 203 contract chain.
Your team picks gpt-oss-120b, Qwen or Ministral per task, works with knowledge bases, assistants and dictation, and signs in via SSO. We handle operations, updates and new models.
Concrete Use Cases
Open WebUI brings chat interface and RAG pipeline - but enterprise requirements demand more. We extend the frontend for your use cases.
Problem
Different requests (code vs. text vs. analysis) need different models, but users shouldn't have to worry about it.
Solution
Pipeline that analyzes input and automatically routes to the optimal model (GPT-4, Claude, local Llama) - transparent to the user.
Problem
Internal documents (SharePoint, Confluence) should be searchable in chat without manually uploading them.
Solution
Automatic sync of enterprise documents into vector DB. With every question, relevant context from the knowledge base is injected.
Problem
LLM responses could contain sensitive info (PII, internal codes). Must filter before display.
Solution
Output pipeline that scans responses and masks or blocks sensitive data before displaying to user.
Open WebUI managed service

Other operating models
Hosting only, without modelsOpen WebUI as your own instance in Germany, Switzerland or Austria on a compute size from XS to XL, with updates, backups and monitoring. You bring your own models and API keys; WZ-IT does not provide a model connection. A confidentiality agreement under Section 203 German Criminal Code (StGB) is available on request at the German location; for professional secrecy holders there is also the AI platform or the Section 203 managed cloud.
Configure hosting →Platform on premisesOpen WebUI on a WZ-IT App Node at your company, chats and knowledge bases stay in house; the models run on AI hosting by a German provider in Germany.

Every organisation gets its own instance on its own domain, with no data shared with other customers. Access and identity are part of the platform from the start.
Reachable publicly via TLS or only from your network and via VPN, for example with NetBird.
SSO with Microsoft Entra ID, Google or Keycloak, multi-factor sign-in and permissions per group.
Your organisation's chats, knowledge bases and assistants, hosted in Germany by German providers, on the App Node or on AI Cube.
gpt-oss-120b, Qwen and Ministral, operated in Germany by German providers, without US clouds; local on AI Cube.
Knowledge bases with search and reranking, text recognition for scans and Office files.
Web search, assistants and interfaces; custom extensions as an additional service.
Hosted, on the App Node or on AI Cube: the setup stays the same, only the location of the instance and the models changes.
Role in the overall system
This page covers installation and the agreed platform operations for Open WebUI. Custom code, the access layer and special confidentiality requirements remain clearly separated responsibilities that can be added when needed.
Keep custom extensions, interfaces and dependencies controlled, updated and supportable.

Knowledge
Reviews & projects
From a knowledge base with an AI assistant and local AI integration to data sovereignty and ongoing operations.
AI Platform
We were looking for a secure yet easy-to-use alternative to the large American providers and came across WZ-IT. WZ-IT advised us on choosing the right models and implemented the integration for us. Beforehand, we were able to try everything out calmly on a test instance. Today WZ-IT runs Open WebUI for us on our own domain, with a convenient Microsoft login and open-source models hosted by a German provider. Our team can now work productively with AI without resorting to external tools or shadow AI. Working together is straightforward, and questions are answered quickly and clearly. With WZ-IT we also have a partner at our side for further AI projects. (translated)
Carl-Frederic KornHead of E-Commerce & Online Marketing, Krüger Dirndl GmbHKnowledge Management & AI
The knowledge from many years in the solar industry lived in the head of our former managing director, and it still lives in the heads of our employees today. We wanted to secure it, not as a folder full of notes, but in a way that lets us ask questions in daily work and get reliable answers. WZ-IT advised us from the start and weighed different approaches and knowledge management systems against each other with us before we decided. What was built is a custom knowledge base with an AI assistant that brings together conversations, notes, documentation and manuals: from the platform through onboarding our team to support in operation. Conversations are transcribed and facts are extracted; we review and correct everything ourselves before it is stored, because we do not want to trust an AI blindly. The system runs in our own environment, and the data stays with us. What surprised us was how efficient it was: WZ-IT used existing open-source software and extended it specifically for our requirements, instead of selling an expensive custom build from scratch, as is often usual with IT service providers. Timo and Robin understood our actual problem, preserving knowledge during the generational handover, and implemented it step by step: from the proof of concept through setup and validation with our own data to productive operation, explaining everything clearly along the way. Next, we want to extend this to the knowledge of our employees, so that this does not depend on individual people either.
