cPanel is one of the best web hosting Control Panel tools and it is used by millions of users globally. Its popularity is due to its convenience and intuitive interface, which will allow you to access a number of functions with just a couple of clicks. You're able to upload, copy and move files, create new databases and add users with different levels of access, create e-mail addresses, enable spam protection and SPF validation, view account usage stats, and many more. cPanel is used by many reseller website hosting providers, due to the fact that it comes with a reseller-level Control Panel called WebHost Manager (WHM). The latter is a powerful tool which will enable you to create hosting packages and to select all of their features. You can also generate and modify client web hosting accounts, access and edit a variety of server-side settings and DNS zone records, set up modules and apps, and many more. cPanel and WHM can be used with countless billing apps.
