Opening a UI
Click Web UI on a running instance. GPUtw uses a port-prefixed subdomain such as 8080-<instance-id>.gputw.ai and validates ownership before proxying traffic.
Access modes
Ports can be private, public, or unlisted with a password. Use public/unlisted only when the app has its own security or the data is safe to expose.
Brave browser ipywidgets issue
If Jupyter or ipywidgets fail to render in Brave, Brave Shields may be blocking JavaScript CDNs such as unpkg or jsdelivr. Disable Shields for the instance UI domain or allow the required scripts, then reload Jupyter.
