Free source-available software; branding conditions apply
How I use Open WebUI
I run Open WebUI on my Fedora workstation as the browser interface for local models and supported model APIs.

One browser interface can connect to local model runtimes and compatible hosted APIs. Its current licence is source-available and includes branding conditions.

Who it is for
A self-hosted browser interface for local and compatible hosted AI models.
Who can claim it?
The source and self-hosting instructions are publicly available. A model runtime or compatible API is separate.
What the free software includes, and what costs extra
The current licence is not an OSI open-source licence and includes branding restrictions for deployments above the stated user threshold. Models, hardware and hosted APIs remain separate.
Billing and renewal
There is no recurring software charge under the published licence terms; infrastructure and model access remain separate.
