cPanel is the most widespread Control Panel tool on the web hosting market. It is feature-rich and has an easy-to-use interface that will supply you with full control of your Internet sites. It is simple to control files, e-mails and databases, take a look at usage statistics, install script-driven apps, and the like. The software is preferred by many web hosting companies, since it also has a reseller counterpart called WebHost Manager (WHM). This instrument will supply you with a web-based graphical interface, through which you are able to manage lots of server-side settings, create website hosting plans or new customer accounts and modify their features with only a few clicks. You can also set up different modules and apps, adjust DNS records, brand all the cPanel accounts that your clients will get, create and remove features from their Control Panels, etc. cPanel and WHM are compatible with nearly all billing apps out there, so this is among the best platforms in case you wish to become a reseller.
