cPanel is the most popular Control Panel instrument on the web hosting market. It's feature-rich and it features an easy-to-use interface that will offer you full control of your web sites. It is simple to manage files, email addresses and databases, view usage statistics, set up script-driven applications, and many others. The software is preferred by many web hosting companies, because 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 take care of numerous server-side settings, generate web hosting packages or new customer accounts and modify their features with only a couple of clicks. You may also install different modules and apps, customize DNS records, brand the cPanel accounts that your clients will get, create and remove features from their Control Panels, and so on. cPanel and WHM are supported by almost all billing applications out there, so this is one of the best platforms in case you would like to become a reseller.
