cPanel (with its admin side WHM) defined how hosting servers are organised: accounts under /home, Apache vhosts per domain, per-domain access logs, Exim for mail, MySQL databases per account.
That standardisation is why so much tooling “just works” on cPanel-style servers — monitoring, security scanners and migration tools all rely on the conventional layout to find logs, configs and per-account data.
Frequently asked questions
What is the difference between cPanel and WHM?
WHM is the server administrator’s interface (creating accounts, server settings); cPanel is what each hosting customer sees for their own account.
Why do alternatives advertise “cPanel-style” layouts?
Because the ecosystem expects it — admins and tools know where everything lives, which lowers the cost of switching panels.
