Open-source personal cloud system with a web dashboard, app store, and file management to run and manage Docker apps on home servers and SBCs.

CasaOS is an open-source personal cloud system that provides a web-based dashboard for running and managing self-hosted applications on a home server. It is designed to make Docker-based app deployment and basic server management accessible on common hardware like mini PCs and single-board computers.

Key Features

  • Web UI tailored for home-server scenarios with a simple, “no forms” setup experience
  • App store and one-click installation for curated, community-verified self-hosted apps
  • Support for installing and managing many Docker applications from the wider container ecosystem
  • Built-in drive and file management features for local storage organization
  • Dashboard widgets for quick visibility into app status and system resource usage
  • Broad hardware and Linux distribution compatibility (x86_64 and ARM variants)

Use Cases

  • Run a personal home server to host common self-hosted apps (cloud storage, media, DNS, home automation)
  • Provide a lightweight “personal cloud” interface for managing Docker apps on a NAS-like device
  • Set up a beginner-friendly homelab dashboard on Raspberry Pi, NUCs, or repurposed PCs

Limitations and Considerations

  • Functionality depends heavily on the Docker ecosystem; non-containerized apps are not the primary focus
  • The project has been positioned by its maintainers as evolving toward ZimaOS, which may affect long-term direction and feature focus

CasaOS is well-suited for users who want an approachable UI to deploy and monitor Dockerized services at home. It focuses on simplifying day-to-day app management while remaining flexible enough to install a wide range of container-based software.

OpenMediaVault is a Debian-based network-attached storage (NAS) solution designed to simplify deploying and managing shared storage via a web administration interface. It bundles common storage and file-sharing services and can be extended through a modular plugin framework.

Key Features

  • Web-based administration for storage, users, permissions, and services
  • Built-in file transfer and sharing services such as SMB/CIFS, (S)FTP, rsync, and SSH
  • Modular plugin architecture to add features and integrations
  • Supports Linux software RAID management (mdadm) and common disk/filesystem workflows
  • Designed for home environments and small offices, while remaining flexible for other setups

Use Cases

  • Home NAS for centralized file storage and backups across multiple devices
  • Small office shared storage with user/group access controls and SMB shares
  • DIY server base for adding storage-related services through plugins

Limitations and Considerations

  • Intended to run as the primary OS with full control over system configuration; it is not designed to run inside a container
  • A graphical desktop environment is not meant to be installed alongside the NAS stack

OpenMediaVault provides an approachable NAS experience on top of Debian, combining a practical web UI with widely used network storage services. Its plugin ecosystem makes it a strong option for building a tailored storage server without extensive Linux administration expertise.
