cPanel is the most popular Control Panel instrument on the website hosting market. It is feature-rich and it features an easy-to-use interface which will provide you with full control over your sites. It's easy to manage files, e-mails and databases, view usage statistics, install script-driven applications, etcetera. The software is preferred by many hosting companies, since it also has a reseller counterpart called WebHost Manager (WHM). This tool will provide you with a web-based graphical interface, via which you are able to take care of a lot of server-side settings, generate hosting packages or new customer accounts and modify their features with just a few clicks. You may also install different modules and apps, change DNS records, brand all of the cPanel accounts that your customers will get, create and remove features from their Control Panels, and many others. cPanel and WHM are compatible with nearly all billing apps out there, so this is one of the best platforms in case you would like to become a reseller.
