cPanel Softaculous App Installer
Softaculous is a commercial script library that automates the installation of commercial and open source web applications to a website.
Softaculous currently has 419 installer scripts and is very well maintained so you can be confident if you install an application through here that your getting the latest version in the fastest way possible.
As a techno-geek I can’t tell you how many hours I've spent on a command-line interface trying to install and update servers. cPanel and Softaculous are a true time and life saver!
