Basement for Web
The web app is the whole of Basement: your library, Discover, channels, music, reading, Movie Night and the admin pages. The server serves it, so there’s nothing to install.
It works in a phone’s browser too, and it can cast to a Chromecast.
A current Chrome, Edge, Firefox or Safari

Open your server's address
At home it's the address the installer showed, like http://your-server:8484.
