Overview
Description

CasaOS is an open-source home cloud system that turns a spare machine or Raspberry Pi into a personal server. It sits on top of Docker and provides a web dashboard and an app store, so self-hosted applications can be installed and managed without working directly with containers on the command line.

Plesk is a hosting control panel and server management platform for web professionals, offering a centralized dashboard to manage multiple websites, servers, and hosting infrastructure. It provides broad security controls across the OS, network, and applications, plus WP Toolkit for WordPress installation, staging, and updates. Unlike cPanel, Plesk supports both Linux and Windows servers and works across major cloud providers including AWS, Azure, Google Cloud, and DigitalOcean. Over 100 extensions cover SSL, backups, Docker, and developer tooling, making it popular with agencies and IT admins managing mixed environments.
