What is Open WebUI?
Open WebUI hosting on your own VPS.
Open WebUI gives you a ChatGPT-style chat in your browser that you fully control: ask questions, summarize PDFs, chat with your own documents and switch between AI models in one clean interface. Plug in your own API keys or an Ollama server, and every conversation stays in your account. At ZAP-Hosting, this self-hosted ChatGPT experience runs on your own VPS, installed with one click from the Coolify app marketplace.
Because it is your own VPS and not a locked container, you decide what runs next to it. Coolify handles the Open WebUI Docker setup, updates and restarts, so you never have to touch a docker compose file. With full root access, you can add SearXNG for Open WebUI web search or LiteLLM as an API gateway, set your own firewall rules and keep chats, users and uploads on a server you control.

FAQ
Frequently asked questions about Open WebUI
Answers to the most important questions before you start.
Open WebUI itself is free to use. You only pay for the VPS it runs on: choose from our VPS plans with live prices in the shop and cancel anytime. If you connect a paid API provider such as OpenAI, that provider bills its usage separately.
- Open WebUI software: free to use
- VPS: plans with live shop prices
- API usage: billed by your provider
Order a VPS, open the Apps tab in your panel and install Open WebUI with one click from the Coolify app marketplace. Once the container is running, open the URL, create the first account, which becomes the admin, and connect your API keys or an Ollama server. Read the One-Click Apps guide
- Choose a VPS plan and location
- Install Open WebUI from the Apps tab
- Create your admin account and add a model connection
It depends on how you use it. As an interface for OpenAI-compatible APIs, Open WebUI is lean, so a smaller plan is a good start. Document uploads with local embeddings and more users need extra headroom. Running local models with Ollama needs far more RAM, and our VPS for Ollama is the better fit for that.
- API-only use: start with a smaller plan
- Many documents or users: plan more RAM
- Local models: choose the VPS for Ollama
Yes. Open WebUI runs on your own VPS with full root access, not inside a shared SaaS account. Choose your data center from our locations in Europe and America, ideally close to you and your users; many US teams start with Ashburn, Dallas or Los Angeles. HTTPS on your own domain, the network firewall and DDoS protection keep access under your control.
- Your own VPS with root access
- Locations in Europe and America to choose from
- HTTPS, firewall and DDoS protection
Yes. The first account becomes the admin. You decide whether new sign-ups are allowed, need approval or are disabled, and you assign user or admin roles and groups. Every user keeps a private chat history. Plans scale by RAM, CPU and storage, not by user slots.
- Admin, user and pending roles
- Groups with model access control
- Private chats per user
Yes. Start with a smaller plan and switch to a bigger one in your panel when you add users, upload more documents or run extra tools such as SearXNG next to Open WebUI. You scale RAM, CPU and storage, never user slots.
- Plan change right in your panel
- Scale RAM, CPU and storage
Not manually. Coolify runs Open WebUI as a Docker container for you and takes care of the docker compose setup, restarts and your domain with HTTPS. To update, you redeploy the latest image in Coolify with one click. With root access, you can still work with Docker directly whenever you want. Learn more about Coolify
- Coolify manages the container
- Updates with one click
- Docker via SSH stays available
On your VPS. Open WebUI keeps chats, user accounts, settings and uploaded documents in its persistent data volume on your server, not on a third-party platform. A daily automatic Backup of your VPS is included. With the ZapX Pass you can view and restore these daily Backups and add your own manual Backups and snapshots. How Backups work in ZapX
- Chats and uploads stay on your server
- Daily automatic Backup included
- Restore, manual Backups and snapshots with ZapX Pass

Why is Open WebUI so slow when I upload PDFs?
Document uploads create embeddings, which uses CPU and RAM. I can check your current usage first. If memory is close to its limit, an external embedding API or a larger plan are the usual next steps.
Can you show me the current RAM usage?
Sure. I'll read the live stats from your VPS and show you which container uses the most memory, so you can decide what to do next.
