Control panels play a crucial role in web hosting by providing an interface for managing servers, websites, domains, emails, databases and more. The three main control panels used by most web hosts today are cPanel, Plesk and DirectAdmin. Choosing the right control panel is important as it can impact the ease of use, features available and scalability. This article will compare cPanel, Plesk and other alternatives to understand their key capabilities and help determine the best option based on specific needs.
Overview of cPanel
cPanel is one of the most popular control panels for Linux-based web hosting. Originally launched in 1996, it is developed by cPanel Inc. With over 70 million domains hosted on cPanel servers, it has a vast community of users and developers that contribute to its growth.
Some key features of cPanel include:
