cPanel is the most widespread Control Panel tool on the website hosting market. It's feature-rich and it comes with an easy-to-use interface that will give you full control of your web sites. You can easily manage files, e-mails and databases, view usage statistics, set up script-driven applications, etcetera. The software is preferred by many website hosting companies, as it also has a reseller counterpart named WebHost Manager (WHM). This software instrument will supply you with a web-based graphical interface, via which you are able to take care of a number of server-side settings, create hosting plans or new customer accounts and adjust their features with only a couple of clicks. You may also install different modules and applications, change DNS records, brand all of the cPanel accounts that your customers will get, add and remove features from their Control Panels, etc. cPanel and WHM are supported by almost all billing applications out there, so this is among the best platforms in case you wish to become a reseller.
