Introduction
The Application Manager in cPanel is a powerful interface used to manage web applications that run in custom environments like Python, Ruby, and Node.js. It allows you to create, configure, and control these applications from a visual dashboard — making it easier to deploy apps without extensive command-line experience.
This article explains how to use the Application Manager in cPanel to manage your custom web applications.
