cPanel ("Control Panel") is a graphical web-based web-hosting control panel, designed to make administration of websites easy. cPanel handles all aspects of website administration in its interface. The software, which is proprietary and distributed by cPanel Inc., is designed for use by commercial web hosting services, so the company does not offer a reduced-cost personal use license; however, owners of non-profit organizations such as educational institutions and charities can request a license at a reduced cost. Reduced prices are frequently available from dedicated-server companies, who install it along with the operating system.

cPanel runs on a number of popular RPM-based Linux distributions, such as SUSE, Fedora, Mandriva, CentOS, Red Hat Enterprise Linux, and cAos, as well as FreeBSD. Preliminary support for Debian is claimed, although this version has been in "beta" state for several years, and is not supported. cPanel is commonly accessed on ports 2082 and 2083 (for an SSL version). Authentication is either via HTTP or web page login.
