cPanel is the most popular Control Panel instrument on the web hosting market. It is feature-rich and it features an easy-to-use interface which will provide you with full control over your sites. It is simple to control files, email addresses and databases, view usage statistics, set up script-driven applications, and the like. This software is preferred by many hosting companies, due to the fact that it also has a reseller counterpart named WebHost Manager (WHM). The aforementioned software tool will give you a web-based graphical interface, through which you are able to control a lot of server-side settings, set up hosting packages or new client accounts and adjust their features with only a couple of clicks. You can also set up different modules and apps, update DNS records, brand all the cPanel accounts that your customers will get, add and remove features from their Control Panels, and many others. cPanel and WHM are compatible with nearly all billing applications out there, so this is one of the top platforms in case you want to become a reseller.
