Open WebUI –
local, lean & GDPR-compliant

Open WebUI is the leading open-source interface for local AI models. We integrate it fully into your infrastructure – no cloud, no subscription, no data sharing.

What is Open WebUI – and why do we use it?

Open WebUI (formerly known as Ollama WebUI) is an open-source, browser-based chat interface for local language models. The project is actively developed by a large community and is now considered the de-facto standard for running AI models locally in businesses and public-sector organizations.

Unlike commercial solutions such as ChatGPT or Microsoft Copilot, Open WebUI runs entirely on your own hardware within your network. Not a single word your employees type ever leaves your environment. This makes it the ideal solution for industries with high data protection requirements: law firms, tax advisors, medical practices, government agencies, engineering offices, and mid-sized businesses of all kinds.

The interface is intuitively designed – anyone who has used ChatGPT before will feel at home immediately. No training week, no manual. Just open a browser and get started.

Why Open WebUI instead of a cloud solution?

Cloud AI services process your inputs on third-party servers – often in data centers outside the EU. For confidential business data, client information, or personal data, this raises serious data protection concerns.

With Open WebUI on your own hardware, you retain full control. No data processing agreements with US corporations, no third-country transfers, no hidden terms of service.

Open WebUI in detail – what the interface can do

Open WebUI offers far more than a simple chat. Here is an overview of the most important features for professional use.

Multi-model operation

Run multiple AI models in parallel and switch between them mid-chat – no restart required.

Document upload

Load PDFs, Word files, and text documents directly into the chat. The AI reads, analyzes, and answers questions about them.

RAG – your own knowledge base

Permanently embed your own documents (Retrieval Augmented Generation). The AI knows your internal materials.

Image analysis

Upload images to the chat for analysis – using multimodal models such as LLaVA or Qwen-VL.

Voice input

Input via microphone – processed locally. No audio data is transmitted externally.

User management

Individual user accounts for every team member. Chats are private and not shared.

Customizable prompts

Configure system prompts, roles, and templates – the AI behaves exactly as your business needs.

Mobile-optimized

Responsive design – Open WebUI works equally well on desktop, tablet, and smartphone.

Multilingual

English, German, and many more languages – with excellent output quality depending on the selected model.

Open WebUI in practice

This is what Open WebUI looks like at our clients' sites – lean, dark, professional.

How the Open WebUI integration works for you

We handle the complete technical setup – you don't have to worry about a thing. A single on-site appointment is all it takes.

1

Hardware selection & delivery

We advise you on the right hardware (Mac Studio, DGX System, or GPU cluster) and deliver everything pre-configured.

2

Open WebUI installation & configuration

Installation, network integration, user account creation, model loading – all in a single on-site visit.

3

Model configuration to your needs

We set up the language models that suit you best – including multilingual Qwen or Llama models on request.

4

Onboarding & immediate start

A brief walkthrough and you're done. Your team opens a browser, enters the internal address – that's it.

Why use our integration instead of installing it yourself?

Open WebUI is technically demanding to set up – especially when it comes to network integration, user authentication, automated backups, and the interplay with LLM runners.

We have optimized this process many times over. You receive a stable, production-ready system without trial and error. Includes a backup concept, diagnostic package, and remote maintenance option.

And if you would prefer LibreChat – no problem. We set up both interfaces for you, and you decide after the demo which one fits your team better.

Frequently asked questions about Open WebUI

Open WebUI is an open-source chat interface that runs entirely on your own hardware. Unlike ChatGPT, no data is sent to external servers – everything stays within your network. The user experience is equally comfortable, but without subscription costs and with full data control.
Yes – by design. Because Open WebUI runs exclusively in your local network, there is no third-country transfer, no data processing with external providers, and no data sharing. This is structurally more secure than any cloud solution.
All major open-source models: Llama 3, Mistral, Qwen, Gemma, DeepSeek, and many more. The models run via Ollama or a compatible LLM runner on your hardware. You decide which models are loaded – we configure everything.
Yes. Open WebUI is designed to run fully offline. An internet connection is not required for chat or AI inference. Updates are applied manually as needed.
This depends on the hardware. A DGX System comfortably supports 10–30 concurrent users; a GPU cluster supports correspondingly more. We size the hardware based on your user count.
Open WebUI is leaner and more intuitive – ideal for businesses that want to get started quickly and prefer a simple user interface. LibreChat offers more features such as a plugin system, customizable assistants, and advanced multi-user management. Both interfaces use the same AI models in the background. We show you both in a demo – you decide from there.
