cPanel is the most popular Control Panel tool on the web hosting market. It is feature-rich and it features an easy-to-use interface which will supply you with full control of your Internet sites. It is easy to control files, email addresses and databases, take a look at usage statistics, set up script-driven apps, etcetera. This software is preferred by many website hosting companies, because it also has a reseller counterpart named WebHost Manager (WHM). This software tool will give you a web-based graphical interface, through which you are able to manage lots of server-side settings, generate website hosting plans or new client accounts and change their features with only a few clicks. You may also set up different modules and applications, update DNS records, brand all the cPanel accounts that your clients will get, add and remove features from their Control Panels, etc. cPanel and WHM are compatible with almost all billing applications out there, so this is one of the best platforms in case you wish to become a reseller.
