What is CasaOS?

What it is

CasaOS is an open-source personal cloud operating system built for home servers. It provides a lightweight, user-friendly interface to manage local storage, run containerized applications, and integrate smart devices—all without requiring deep technical knowledge. The project targets individuals and small households seeking autonomy over their data and infrastructure, replacing reliance on commercial cloud services with a self-hosted alternative.

CasaOS solves the problem of inaccessible personal cloud solutions by abstracting complex infrastructure tasks like Docker orchestration, storage management, and app deployment behind an intuitive UI. It enables non-technical users to run services such as file sync, media servers, home automation, and ad blocking with minimal setup, turning commodity hardware into a functional personal data center.

Key capabilities

  • One-click installation of over 100,000 Docker apps via integrated app store
  • Native support for Nextcloud, Jellyfin, Home Assistant, AdGuard, and *arr suite
  • Visual file and drive management with drag-and-drop interface
  • System resource monitoring and app status widgets displayed on the dashboard
  • Cross-platform hardware support including Raspberry Pi, Intel NUC, ZimaBoard, and x86/ARM devices
  • Built-in update mechanism via UI or CLI for seamless version upgrades
  • Multi-language interface with English, Chinese, and French support

Who uses it and how

Home users deploy CasaOS on Raspberry Pi or old PCs to centralize media, documents, and smart home control. Home automation enthusiasts integrate CasaOS with Home Assistant to unify local device management and AI workflows. Small creators use it to self-host backups, versioned media libraries, and private collaboration tools instead of paying for SaaS subscriptions.

Getting started

Install via one-liner: wget -qO- https://get.casaos.io | sudo bash or curl -fsSL https://get.casaos.io | sudo bash. CasaOS runs as a Docker-based service on Debian, Ubuntu, or Raspberry Pi OS. No hosted option is available; deployment requires local hardware and internet access.

When to use it — and when not to

CasaOS replaces paid personal cloud services but lacks enterprise-grade features like multi-user RBAC, audit logging, or SLA-backed uptime. Users must manage their own database (SQLite by default), storage, and SMTP for notifications—no built-in high availability. It suits hobbyists and small-scale deployments but not production environments requiring scalability or strict compliance.

Why do you need Personal Cloud?

In 2020, the team noticed three important trends:

  • The cost of computing power and storage was decreasing fast.
  • A part of cloud computing was moving towards edge computing.
  • The issue of consumer data asset ownership and attribution had been ignored.

Based on these trends, the team proposed a thought experiment internally: what if personal clouds were available under $100 in next five years? This personal cloud would provide a low-cost data collaboration solution as a personal data center, storing and managing data for creators and small organizations. A distributed collaborative computing network can be formed by personal servers located around the world. It could also control and connect all smart devices, providing cross-ecosystem local intelligent services.

Furthermore, the personal cloud could combine personal data to train personalized AI assistants. The idea is that this technology would be an effective way to solve the issue of consumer data asset ownership and , as well as provide a more affordable and efficient computing solution for individuals and small organizations.

Update CasaOS

CasaOS can be updated from the User Interface (UI), via Settings ... Update.

Alternatively it can be updated from a terminal session. To update from a terminal session, it must be done either from a secure shell (ssh) session to the device or from a directly attached terminal and keyboard to the device running CasaOS, this cannot be done from the terminal via the CasaOS User Interface (UI). To update to the latest release of CasaOS from a terminal session run this command:

wget -qO- https://get.casaos.io/update | sudo bash

or

curl -fsSL https://get.casaos.io/update | sudo bash

To determine version of CasaOS from a terminal session run this command:

casaos -v

Uninstall CasaOS

casaos-uninstall

Before v0.3.3

curl -fsSL https://get.icewhale.io/casaos-uninstall.sh | sudo bash

Community

The word Casa comes from the Spanish word for "home". Project CasaOS originated as a pre-installed system for the crowdfunded product ZimaBoard on Kickstarter.

After looking at many systems and software on the market, the team found no server system designed for home scenarios, sadly true.

So, we set out to build this open-source project to develop CasaOS with our own hands, everyone in the community, and you.

We believe that through community-driven collaborative innovation and open communication with global developers, we can reshape the digital home experience like never before.
