This allows users to access multiple AI systems through a single interface.

Prerequisites

Before installing Open WebUI, ensure you have one of the following:

Option 1 – Docker (Recommended)

Verify Docker installation:

docker --version

Option 2 – Python

Verify Python installation:

python --version

Python 3.11 or newer is recommended.

Step 1 – Install Open WebUI Using Docker

The quickest installation method is Docker.

Run:

docker run -d \
-p 3000:8080 \
-v open-webui:/app/backend/data \
--name open-webui \
ghcr.io/open-webui/open-webui:main

This command:

  • Downloads Open WebUI
  • Creates persistent storage
  • Starts the application
  • Exposes the web interface on port 3000

Step 2 – Open the Application

Open your browser and navigate to:

http://localhost:3000

You will see the Open WebUI welcome screen.

Step 3 – Create an Administrator Account

When Open WebUI starts for the first time:

  1. Create your administrator account.
  2. Enter your email.
  3. Create a password.
  4. Complete the setup process.

The first registered user automatically becomes the administrator.

Step 4 – Connect AI Models

Open WebUI supports both local and cloud-based AI models.

Option A – Connect Ollama

Install Ollama:

curl -fsSL https://ollama.com/install.sh | sh

Download a model:

ollama pull llama3

Start Ollama:

ollama serve

Open WebUI automatically detects the Ollama server.

Option B – Connect OpenAI

Navigate to:

Settings → Connections → OpenAI

Add your API key:

OPENAI_API_KEY

Save the configuration.

Option C – Connect Gemini

Navigate to:

Settings → Connections → Google Gemini

Add your Gemini API key.

Option D – Connect Claude

Navigate to:

Settings → Connections → Anthropic

Add your Anthropic API key.

Step 5 – Start Chatting

Once a model is connected:

  1. Click New Chat.
  2. Select a model.
  3. Enter your prompt.
  4. Receive AI-generated responses.

Open WebUI supports switching between multiple models from a single interface.

Step 6 – Upload Documents

Open WebUI supports file uploads.

Examples:

  • PDF Files
  • Word Documents
  • Text Files
  • Knowledge Bases

Uploaded files can be used to provide context during conversations.

This enables document-based AI interactions.

Step 7 – Create Knowledge Bases

Knowledge Bases allow AI models to answer questions using your own data.

Examples:

  • Company Documentation
  • Product Manuals
  • Internal SOPs
  • Research Material
  • Client Information

The AI can search these sources before generating responses.

Step 8 – Create AI Agents

Open WebUI supports agent-based workflows.

Examples:

Customer Support Agent

Answers customer questions using company knowledge.

Research Agent

Searches and summarizes information.

Documentation Agent

Creates technical documentation.

Internal Assistant

Helps employees access company information.

Agents can be customized with instructions, tools, and knowledge sources.

Step 9 – Use Pipelines

Pipelines extend Open WebUI functionality.

Examples:

  • Custom Workflows
  • External API Integrations
  • Data Processing
  • AI Automations
  • Business Logic

Pipelines allow developers to build complex AI systems without modifying the core platform.

Advanced Features

Multi-Model Support

  • Azure
  • Google Cloud
  • DigitalOcean
  • Kubernetes Clusters
  • Private Infrastructure

This flexibility allows organizations to maintain full ownership of their data.

Why Use Open WebUI?

Many AI platforms lock users into a single provider and store conversations on external infrastructure.

Open WebUI gives users:

  • Complete ownership of data
  • Local AI support
  • Multi-model flexibility
  • Open-source transparency
  • Team collaboration features
  • Knowledge base integrations
  • AI agents and workflows
  • Enterprise deployment options

Because it is self-hosted and highly extensible, Open WebUI has become one of the most popular open-source AI platforms available today.
