FROM ZERO TO HERO
The map before
the journey
See the platform as connected layers: interface, model providers, knowledge, tools and operations. That map prevents configuration by guesswork.
THE GUIDE / 00—18
A clear path through
the complexity.
All nineteen chapters are complete English web editions, individually structured with their original covers, diagrams and interface captures.
Roadmap & Architecture
A working mental model for the system you are about to build.
What Is Open WebUI?
A practical tour of Chat, Workspace, Settings and Admin.
Installing Open WebUI Properly
Build a home for your AI that you can update and recover.
Understanding Local LLMs
Choose a local model with evidence instead of folklore.
Choosing & Configuring Models
Turn a capable model into an assistant with a clear role.
Administration & Security
Design access that stays understandable as the instance grows.
Knowledge & RAG from Zero
Build a trustworthy path from documents to grounded answers.
Advanced RAG
Tune retrieval as an engineering problem.
Tools & Functions
Move from answers to deliberate, reviewable actions.
MCP & Connectors
Connect services without losing control of what can happen.
Agents
Build multi-step work that remains inspectable and bounded.
Coding Agents
Give an agent a workspace without giving up engineering practice.
Pipelines & Automation
Turn repeatable work into a system you can trust.
APIs & Building Your Own Applications
Build your own experience on a controlled AI backend.
Security Hardening
Place the platform behind clear, tested protections.
Observability & Troubleshooting
Diagnose the stack without collecting random fixes.
Performance & Optimization
Improve speed by measuring the right constraint first.
Building Our Open WebUI Platform
Assemble the system from deliberate, observable parts.
Cookbook
Turn the guide into practical, repeatable outcomes.
THE APPROACH
Understand first.
Configure with confidence.
Know what each layer does.
Separate the interface, inference, knowledge and actions. A clear mental model makes every setting easier to understand.
Learn with your own setup.
Read a Compose file, inspect a running model and try a focused prompt. Make the ideas concrete, one step at a time.
Be able to explain your choices.
Each chapter ends with questions. Keep going when you understand why your configuration works.
