Cockpit
Cockpit allow to manage a system via a web interface instead of via ssh and command-line. It integrates many dashboard and tools to make common management tasks easier.
apt install cockpit
To make sure that cockpit only listens for local connections, create the file /etc/systemd/system/cockpit.socket.d/listen.conf (the parent directory might need to be created), with the following content (note that the empty value in the first line is required to reset the default behaviour).
[Socket]
ListenStream=
ListenStream=127.0.0.1:9090
FreeBind=yes
After that, execute systemctl daemon-reload && systemctl restart cockpit.socket
