Fedora - Cockpit comes installed by default in Fedora Server.

Cockpit is a server administration tool sponsored by Red Hat, focused on providing a modern-looking and user-friendly interface to manage and administer servers. 

Fedora 21 included Cockpit by default, and since then, it has continued to grow and mature. 

Red Hat Enterprise Linux 7 included Cockpit in the optional and extras repositories, and it’s included in Red Hat Enterprise Linux 8 by default.

Cockpit is not the first of its class (many old-time system administrators may remember Webmin), but the alternatives are usually clunky, bloated, and their underlying APIs may be a security risk. 

That’s where Cockpit is different and shines. With Cockpit, unnecessary services or APIs don’t get in the way of doing things. Quelle: [https://www.redhat.com/sysadmin/intro-cockpit]
