Runs on a private AI box you own
One compact GB10-class device — 128 GB unified memory — runs it on-premise, sold and provisioned by us. No cloud API keys, no data leaving the building.
Run Open WebUI on a private AI box
License: source-available (not OSI)
A polished, self-hosted chat front-end for local and OpenAI-compatible models — one of the most widely deployed private AI interfaces.
What it is
- A feature-rich web UI for chatting with local models, with users, roles, and document Q&A.
- Connects to OpenAI-compatible servers and to local runtimes.
- Self-hosted: you run it next to your model on your own network.
Open WebUI ships under the "Open WebUI License" — a source-available license with a branding clause, not a standard OSI-approved open-source license. We label it accurately rather than calling it "open source".
Open WebUI is an independent project. BrainOutput has no affiliation, endorsement, or partnership with it — we sell the private hardware you can run it on. Project: Open WebUI.
Cloud API keys vs your private box
The tool is the same either way. What changes is where your prompts and files go, and how you pay.
| Cloud API keys | Your private box | |
|---|---|---|
| Data location | Prompts and files are sent to a third-party API | Everything stays on hardware in your office |
| Cost model | Metered per token — scales with usage, indefinitely | A fixed hardware cost — local inference is unmetered |
| Availability | Vendor uptime, rate limits, and model retirements apply | Runs offline; you control uptime and model versions |
| EU compliance | Data-transfer and processor terms to manage per vendor | EU hardware on your premises — sovereignty is physical, not contractual |
| Model choice | Whatever the vendor exposes | Any open-weight model that fits the box — swap freely |
Indicative hardware start prices are €3 650,22 HT (ASUS) / €4 328,25 HT (Dell); the full sovereign setup is sur devis.
How it connects to your box
In Settings → Connections, add an OpenAI API connection pointing at the model server on your box.
- Enter the base URL of your box's OpenAI-compatible endpoint.
- Select the served model — inference then runs locally, no external key needed.
How BrainOutput fits
- We deliver the device and the model endpoint Open WebUI connects to.
- You keep the UI and its user data entirely on-premise.
Frequently asked questions
- Is Open WebUI open source?
- It is source-available: the code is public but its license (the Open WebUI License) is not OSI-approved and adds a branding clause. We say so plainly.
- Does it need the cloud?
- No. Pointed at your box's endpoint it runs fully offline, with the model on your own hardware.
- Can it do document Q&A privately?
- Yes — its retrieval features work against your documents while everything stays on your infrastructure.
Run it on a box we set up for you
We size the device, install an OpenAI-compatible model stack, and hand you the endpoint this app points at. The app stays free and yours.
