cPanel is the most widely used Control Panel tool on the hosting market. It's feature-rich and it features an easy-to-use interface that will supply you with full control of your Internet sites. It is easy to control files, emails and databases, view usage statistics, set up script-driven applications, and the like. This software is preferred by many website hosting companies, since it also has a reseller counterpart called WebHost Manager (WHM). The aforementioned software tool will offer you a web-based graphical interface, via which you're able to manage a lot of server-side settings, set up website hosting packages or new customer accounts and modify their features with just a couple of clicks. You can also set up different modules and apps, adjust DNS records, brand all of the cPanel accounts that your clients will get, add and remove features from their Control Panels, and so on. cPanel and WHM are compatible with the vast majority of billing applications out there, so this is one of the best platforms in case you would like to become a reseller.
