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.

Webmin is a free, open-source web-based system administration tool for Unix-like servers, with roughly one million installations worldwide. It lets administrators configure operating system internals such as users, disk quotas, and services, and manage popular open-source software including BIND DNS, Apache, PHP, and MySQL through a browser. Recent releases have added modules for nftables firewall management, Nginx configuration, and systemd service control, plus enterprise-oriented features like role-based access and two-factor authentication. Its companion projects, Usermin and Virtualmin, extend it into a user-facing panel and a full hosting control panel respectively.

The Verdict

AI-generated from listing data

CasaOS offers a user‑friendly, Docker‑based home‑server UI for personal or small‑team use, while Webmin provides a broader, low‑level Linux admin console for experienced sysadmins.

Key differences

  • •CasaOS focuses on one‑click Docker app deployment for home servers; Webmin manages core Linux services and system settings.
  • •CasaOS includes a built‑in app store and dashboard; Webmin relies on modules for individual services like Apache, MySQL, etc.
  • •CasaOS is optimized for modest hardware (Raspberry Pi, old PCs); Webmin runs on any Linux distro but expects more resources for full admin tasks.
  • •CasaOS is open source with community support and no API; Webmin also open source, adds role‑based access, 2FA, and community modules.
