While ntfy doesn't have a native desktop app, it is built as a [progressive web app](https://developer.mozilla.org/en-US/docs/Web/Progressive_web_apps)
and thus can be installed on both desktop and mobile.
This gives it its own launcher (e.g. shortcut on Windows, app on macOS, launcher shortcut on Linux) own window,
push notifications, and an app badge with the unread notification count.
To receive background notifications, either the browser or the installed web app must be open.
