cPanel is the most widespread Control Panel tool on the website hosting market. It is feature-rich and it comes with an easy-to-use interface that will give you full control of your web sites. It is simple to manage files, emails and databases, view usage statistics, install script-driven apps, etcetera. This software is preferred by many web hosting companies, because it also has a reseller counterpart called WebHost Manager (WHM). This software instrument will provide you with a web-based graphical interface, via which you are able to handle numerous server-side settings, set up website hosting packages or new customer accounts and change their features with just a couple of clicks. You may also set up different modules and applications, update DNS records, brand the cPanel accounts that your clients will get, create and remove features from their Control Panels, etcetera. cPanel and WHM are supported by the vast majority of billing apps out there, so this is one of the best platforms in case you would like to become a reseller.
