Deploy Open WebUI on Ownkube

Open WebUI is a self-hosted chat interface for language models. Connect an OpenAI-compatible API or your own model server in settings, upload documents, and chat. The first account to sign up becomes the admin, so sign up right after deploy. Every chat persists in your own database. Deploy it with a managed Postgres database and a public hostname with automatic HTTPS.

Deploy Open WebUI github.com/open-webui/open-webui

Runs on Ownkube Compute, no cloud account needed. It bills per minute from your prepaid wallet like any other app. See pricing

How deploying Open WebUI works

01
Click Deploy

The deploy flow opens on your Ownkube canvas. If you are signed out, you sign in first and land right back in it.
02
Pick a region

Choose an Ownkube Compute region. Open WebUI needs nothing else from you.
03
Open your app

The database comes up first, then Open WebUI, already wired together. Open its HTTPS hostname once it is healthy.

What you get

Works with OpenAI-compatible APIs
Document uploads in chats
Your chats in your own database
Public hostname with automatic TLS

What you provide

Nothing. Defaults are set and secrets are generated for you, and you can reveal them on the deployment afterward.

It shows as one app on your canvas, and deleting it removes the app and its data together.

Or ask your coding agent

With Ownkube connected over MCP, your agent can deploy Open WebUI for you. It reads what the app needs, runs a dry run, deploys the app with its database in one call, and follows it until it is healthy. It asks before it creates or deletes anything.
