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