Last time I checked, homebrew on Linux only included cli apps. GUI apps are only available on mac. So you couldn’t use it to install a browser anyway.

Spotube should be able to download tracks: https://spotube.krtirtho.dev/

Example: I need to enable ntp client on a machine? Just enable and start the service and done!

You don’t need systemd for that. It has always been the case before systemd even existed.
