🌐 What Is CasaOS?
CasaOS is a free and open-source home cloud operating system developed by IceWhale Technology. It transforms your PC, laptop, or single-board computer (like a Raspberry Pi) into a personal cloud platform.
In simple terms, CasaOS lets you host and manage apps, files, and media locally — just like you would on a NAS (Network Attached Storage) or cloud service — but without relying on external companies.
🔹 Key Features of CasaOS
- Beautiful Web Interface: CasaOS offers a clean, modern, and intuitive interface accessible through any browser.
- Docker App Support: You can easily install and manage containerized applications from the App Store or Docker Hub.
- File Management: CasaOS includes a built-in file manager to upload, organize, and access your files remotely.
- Cross-Device Access: Access your server from multiple devices, including phones, tablets, or computers.
- Open Source: Unlike proprietary systems, CasaOS is open-source and community-driven.
- Lightweight and Fast: It’s optimized for low-power devices like the Raspberry Pi, yet powerful enough for full PCs.

🪜 Step-by-Step Installation Guide
Step 1: Update Your System
First, update your system to make sure everything is up-to-date.
sudo apt update && sudo apt upgrade -y

🖥️ How to Use CasaOS
Once installed, you can start customizing your personal cloud.
🧭 1. Explore the Dashboard
The CasaOS dashboard shows system info, storage usage, and app management tools. You can easily navigate between:
- App Store — to install apps
- Files — to manage documents and media
- Settings — to configure users and storage
📦 2. Install Your Favorite Apps
One of CasaOS’s biggest strengths is its App Store, which offers one-click installation for popular applications like:
- Nextcloud – your personal cloud storage
- Jellyfin – a media server for movies and shows
- Home Assistant – smart home automation
- qBittorrent – torrent download manager
- PhotoPrism – photo management system
You can also install custom Docker containers from Docker Hub directly through the interface.
📂 3. Manage Your Files
CasaOS includes a powerful file manager where you can:

- Create folders
- Rename and delete items
- Share files across your network
You can access your files remotely through your browser or connect via Samba (SMB) for local network access.

CasaOS allows you to set passwords and access control to ensure your data stays private. You can also configure:
- HTTPS access (via reverse proxy or domain)
- Local backups to external drives
- Firewall rules for added protection
🚀 Why CasaOS Stands Out
CasaOS is not the only self-hosted platform out there — but it’s one of the easiest to use. Compared to alternatives like OpenMediaVault, TrueNAS, or Nextcloud, CasaOS offers:
| Feature | CasaOS | TrueNAS | OpenMediaVault |
|---|---|---|---|
| User-Friendly UI | ✅ | ❌ | ⚠️ |
| Docker App Store | ✅ | ⚠️ | ✅ |
| Easy Installation | ✅ | ❌ | ⚠️ |
| Lightweight | ✅ | ❌ | ✅ |

CasaOS is perfect for those who want a plug-and-play personal cloud system without diving deep into complex configurations.
