How we work with you

You don’t have to build Open WebUI alone. We accompany you step by step – and stay by your side afterwards.

Step 1

Analysis & concept

We look at your use cases, user groups and existing models and plan together what your AI interface should look like. We know the pitfalls from practical experience - so you avoid a stand-alone solution that nobody uses and one that fails to meet your data protection requirements.
"
Step 2

Structure & integration

We set up Open WebUI to suit your needs: Connection of your models (locally or via API), RAG via your documents, user administration and roles - neatly integrated via Docker or Kubernetes. A well thought-out setup saves you expensive conversions later on and grows with your teams.
"
Step 3

Commissioning & rollout

Your AI interface goes live, teams chat with the right models and access your knowledge base via RAG. This avoids the proliferation of shadow AI tools - all working in a controlled, GDPR-compliant environment.
"
Step 4

Support & Operation

On request, we can take over ongoing operations completely (outsourcing) or support your team with support and training. Updates, user management and availability cost a lot of time internally - we keep your AI platform stable so that you can concentrate on your core business.

Open WebUI Features

Operate your own GDPR-compliant AI interface on your infrastructure – chat, RAG and user management in one tool

All models in one interface

Open WebUI connects local models to any OpenAI-compatible provider via Ollama or vLLM. Your team chats via a familiar, ChatGPT-like interface – local and cloud models can be used and compared in parallel.

RAG about your documents

Upload documents or set up a knowledge database from which the AI draws specific answers – with references. The model answers questions based on your own content instead of guessing.

Self-hosted & GDPR-compliant

Open WebUI runs entirely on your infrastructure, completely offline if desired. Calls, documents and prompts remain in your network – ideal for privacy-sensitive and isolated environments.

User management for teams

With role-based rights administration (RBAC), an entire team shares an installation with a clean separation of authorizations – from small teams to regulated corporate environments.

Expandable with Python

Using functions, tools and pipelines, you can extend Open WebUI with your own logic – from web searches and tool calls to complex orchestration. Hundreds of ready-made extensions are available from the community.

Simple deploiyment

Open WebUI is easy to install via Docker or Kubernetes. Updates remain predictable thanks to semantic versioning – and if you wish, we can take over the setup and operation completely for you.

Making AI usable together

We help you to strategically plan, technically implement and sustainably operate modern AI solutions with OpenWebUI. We combine consulting, implementation and support to create a tailor-made service that is geared to your requirements. Our aim is to make access to your AI models transparent, secure and easy for your team to use.
