Deploy Open WebUI on Your VPS
Deploy Open WebUI on your VPS in one click. A self-hosted ChatGPT-style interface for LLMs — connect Ollama or any OpenAI-compatible API with multi-user chat and RAG.
Open WebUI is a polished, self-hosted chat interface for large language models — a private ChatGPT you fully control. Connect it to a local Ollama instance or any OpenAI-compatible API, then get multi-user chat, conversation history, document upload with RAG, prompt libraries, and role-based access, all behind your own domain.
Vessl deploys Open WebUI with a persistent volume for users, chats, and uploaded documents, and enough memory for smooth operation. The first account you register becomes the administrator.

Frequently asked questions
Do I need Ollama to use Open WebUI?
No — Open WebUI works with any OpenAI-compatible API by supplying a base URL and key. Pair it with a self-hosted Ollama server when you want models running entirely on your own hardware.
How do I become the admin?
The first account you register on a fresh install automatically becomes the administrator, who can manage users, models, and settings.
Can multiple people use it?
Yes — Open WebUI is multi-user with role-based access control, so a team can share one instance with separate accounts and chat histories.
