cPanel is the most popular Control Panel instrument on the website hosting market. It is feature-rich and it has an easy-to-use interface which will provide you with full control over your sites. It's easy to take care of files, e-mails and databases, take a look at usage statistics, set up script-driven apps, and so on. The software is preferred by many website hosting companies, due to the fact that it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned tool will provide you with a web-based graphical interface, through which you'll be able to handle numerous server-side settings, set up hosting packages or new client accounts and adjust their features with only a few clicks. You can also set up different modules and apps, change DNS records, brand the cPanel accounts that your customers will get, add and remove features from their Control Panels, etc. cPanel and WHM are compatible with the vast majority of billing apps out there, so this is one of the best platforms in case you wish to become a reseller.
