Open WebUI on your own server, in one click.
Give yourself or your team a ChatGPT-style AI chat with Open WebUI, on a server you own. You pick the models: OpenAI, Anthropic or any OpenAI-compatible API. ServerAvatar runs it in Docker, creates the admin account and turns HTTPS on for you.
- One container
- Admin account created for you
- Your server, your chats
Section 01What is Open WebUI
What is Open WebUI?
Open WebUI is a self-hosted AI chat interface. It works like ChatGPT in your browser, but you choose the models: connect OpenAI, Anthropic, any OpenAI-compatible API or your own Ollama server, and switch between them in one place.
It is built for more than one person. Each user gets their own chat history, and the admin decides who can sign in and which models they can use. Your chats, users and settings stay in a database on your server; messages go only to the model provider you choose.
- Free to use, with its code on GitHub
- No model bundled: bring your own API or Ollama
- Users, groups and per-model access
Section 02Features
What you can do with Open WebUI
Any model, one interface
Chat with OpenAI, Anthropic, any OpenAI-compatible provider or Ollama from one model selector, and switch models mid-conversation.
Multi-model chats
Send the same prompt to two models at once and compare their answers side by side.
Custom models
Wrap any model with a system prompt, tools, knowledge and parameters, and share it with the users or groups you choose.
Users and permissions
Roles, groups and per-model access, with SSO, LDAP and two-factor sign-in when you need them.
Tools and MCP
Add capabilities with Python tools, MCP servers or OpenAPI endpoints, or import extensions from the community.
Organized history
Keep chats in folders, tag and pin them, search your history and share a chat by link.
Section 03Requirements
What you need
A fresh Ubuntu server you can log in to as root. The installer checks all of this before it changes anything.
| Requirement | Open WebUI on Docker |
|---|---|
| Operating system | Ubuntu 24.04 or 26.04 LTS (x86-64) |
| CPU | 1 core or more |
| RAM | 1 GB or more |
| Disk | 10 GB or more (25 GB recommended) |
| Containers | Open WebUI 0.12 (slim image) |
| Ports | 80 and 443 open |
Open WebUI publishes no CPU or RAM minimum; 1 GB is Ubuntu's minimum for a server. Open WebUI's docs measured the slim image at about 300 MiB of RAM at idle. Disk: about 7 GB is in use once the panel and Open WebUI are installed on our test server; 25 GB is Ubuntu's recommendation.
Section 04Install
How to install Open WebUI
Every step happens in the ServerAvatar panel. No terminal needed.
Pick Open WebUI in 1-Click Recipes
On your server, open Applications, click Create application and search for Open WebUI under 1-Click Recipes.
Name it, choose a domain and enter the admin email
Give the app a name and use your own domain, or a temporary one that works right away. Fill in the Admin email field: that address becomes your Open WebUI login. The panel creates a system user for it.
Create it
Click Create application. The panel starts Open WebUI, turns HTTPS on and shows your admin email with the password it generated. Copy them somewhere safe.
Sign in and connect a model
Open the app's domain and sign in with the admin email and the generated password. No model is bundled: go to Admin Settings, Connections and add OpenAI, Anthropic, any OpenAI-compatible API or your own Ollama URL. Sign-up is already closed, so nobody else can register.
