dunst is not possible to run without D-Bus. herbe is a notification helper, but not a daemon. You can make own notifications from scripts and programs calling D-Bus external will also work with that. Everything else using libnotify won't get anything from that.

Tell me please, does it need to be configured using scripts or does herbe work like dunst?

Herbe => Daemon-less notifications without D-Bus. Minimal and lightweight.

Let me correct you. To access a limited list of radio stations, you need to click on view => playlist > Icecast Radio Directory. We will see a small list of private stations..

You can also manually enter links to radio stations as you wrote.

For example, you cannot enter into VLC to select the station you want, etc.

I would like to have a simple graphical application for listening to radio around the world. The radio always works))

Perhaps there are other options..

I would also like to know what is the replacement for the dunst program - notification-daemon?
