cPanel is the most popular Control Panel tool on the hosting market. It's feature-rich and it features an easy-to-use interface which will supply you with full control of your Internet sites. It is simple to take care of files, e-mail addresses and databases, take a look at usage statistics, install script-driven apps, and the like. The software is preferred by many website hosting companies, since it also has a reseller counterpart called WebHost Manager (WHM). This tool will give you a web-based graphical interface, through which you're able to take care of lots of server-side settings, generate website hosting packages or new customer accounts and adjust their features with just a couple of clicks. You can also set up different modules and apps, adjust DNS records, brand all the cPanel accounts that your clients will get, add and remove features from their Control Panels, etcetera. cPanel and WHM are supported by almost all billing applications out there, so this is one of the best platforms if you wish to become a reseller.
