CasaOS vs Umbrel vs YunoHost: Best Self-Hosted Home Server OS 2026

Taking control of your data by running a home server is one of the most rewarding projects you can tackle. Instead of relying on Google Drive, iCloud, or Spotify, you can host your own file sync, media streaming, password vault, and dozens of other services on hardware you own.

The biggest hurdle has always been complexity. Setting up a Lidockerrver, configuring Docker, managing reverse proxies, and keeping everything updated requires significant technical knowledge. That is where home server operating systems come in — they provide a web-based dashboard, one-click app installation, and simplified server management.

In this guide, we compare three of the most popular open-source home server platforms: CasaOS, Umbrel, and YunoHost. Each takes a different approach to self-hosting, and the right choice depends on your technical comfort level, hardware, and what you want to run.

Why Self-Host a Home Server OS

Running your own server operating system gives you advantages that cloud services cannot match:

• Full data ownership — your files, photos, and credentials never leave your hardware
• No subscription fees — one-time hardware cost instead of monthly SaaS charges
• Privacy — no telemetry, no tracking, no corporate data mining
• Always available — your services run 24/7 on your own network
• Customizable — install exactly the apps you need, nothing more

Home server OS platforms take the pain out of setup. Instead of manually provisioning Docker containers, configuring nginx reverse proxies, and managing SSL certificates, you get a polished web interface that handles everything. For NAS solutions like OpenMediaVault or TrueNAS, the focus is on storage and file serving. Home server OS platforms go further — they cover apps, services, and user management.

CasaOS — Personal Cloud for Everyone

CasaOS is an open-source personal cloud system built by IceWhaleTech. With over 33,600 GitHub stars, it is the most popular home server dashboard by raw popularity. CasaOS runs on top of an existing Linux installation (Ubuntu, Debian, Raspberry Pi OS) and provides a clean, modern web interface for managing apps, files, and storage.

Key Features

• One-click app store — browse and install 100+ community apps (nextcloud, Home Assistant, Jellyfin, Gitea, and more)
• File manager — built-in web file browser with upload, download, and sharing
• Storage management — visualize disk usage, mount external drives, configure RAID
• Docker integration — every app runs in a Docker container, easily managed from the UI
• Cross-platform — install on x86 machines, Raspberry Pi, or any Linux server
• Lightweight — minimal resource overhead, runs well on 2 GB RAM systems

Installation

CasaOS installs with a single command on any supported Linux distribution:

1
2

# Install CasaOS on Ubuntu/Debian/Raspberry Pi OS
curl -fsSL https://get.casaos.io | sudo bash

After installation, access the web dashboard at http://your-server-ip:80 (or the port shown in the installer output). The first-run wizard walks through basic setup — creating an admin account and configuring storage locations.

CasaOS App Store Example

Once installed, you can add apps from the built-in store. Here is what a typical deployment looks like for running Jellyfin media server alongside Nextcloud file sync:

# CasaOS handles Docker deployment internally, but you can
# also run containers manually on the same host:

docker run -d \
  --name jellyfin \
  --volume /path/to/media:/media \
  --volume /opt/jellyfin/config:/config \
  --publish 8096:8096 \
  --restart unless-stopped \
  jellyfin/jellyfin:latest

docker run -d \
  --name nextcloud \
  --volume /opt/nextcloud/html:/var/www/html \
  --volume /opt/nextcloud/data:/var/www/html/data \
  --publish 8080:80 \
  --restart unless-stopped \
  nextcloud:apache

CasaOS manages these containers from its dashboard, handling port mapping and volume configuration automatically.

Pros and Cons

Umbrel — The Elegant Home Server

Umbrel positions itself as a beautiful, plug-and-play home server OS. With over 11,000 GitHub stars, Umbrel has built a strong following, particularly in the Bitcoin and privacy communities. Umbrel can run as a full operating system on dedicated hardware (Umbrel Home, Raspberry Pi 5) or install on existing x86 systems.

Key Features

• 300+ app catalog — one of the largest curated app libraries for self-hosting
• Bitcoin and Lightning node — run a full Bitcoin node with built-in Lightning wallet
• Remote access — built-in Tor support and optional Umbrel Cloud for off-site connectivity
• Docker-based architecture — every app runs in an isolated container
• Mobile-friendly UI — responsive design works well from any device

Installation

On x86 systems, Umbrel installs via a script similar to CasaOS:

1
2

# Install umbrelOS on a compatible x86 system
curl -fsSL https://umbrel.com/install | bash

For Raspberry Pi 5, flash the umbrelOS image using Raspberry Pi Imager or dd:

1
2
3

# Flash umbrelOS to a microSD card
# Replace /dev/sdX with your SD card device
sudo dd if=umbrel-os-rpi5.img of=/dev/sdX bs=4M status=progress

After boot, navigate to http://umbrel.local to complete the initial setup wizard. You will create an admin account and optionally configure Bitcoin node synchronization.

App Deployment

Umbrel uses Docker Compose under the hood. Each app in the catalog is defined with a compose file that specifies the container image, volumes, environment variables, and network configuration. When you install an app from the Umbrel app store, the system pulls the image, creates the container, and sets up the reverse proxy automatically.

Pros and Cons

YunoHost — The Complete Server OS

YunoHost is the oldest and most comprehensive of the three platforms. Built on Debian, YunoHost is a full operating system designed from the ground up to make server administration accessible to non-technical users. With nearly 2,900 GitHub stars and an active community since 2012, it has the most mature ecosystem.

Key Features

• Full OS distribution — not just a dashboard, but a complete Debian-based server OS
• 400+ apps — the largest open-source app catalog, including email, CMS, chat, and productivity tools
• Multi-user support — create user accounts, manage permissions, and share resources
• Built-in SSO — single sign-on with a user portal for all hosted services
• Automatic backups — built-in backup and restore for apps and system data
• Email server — full Postfix/Dovecot integration for self-hosted email
• Dynamic DNS — free .nohost.me, .noho.st, or .ynh.fr subdomains
• Debian-based — benefits from Debian’s stability and vast package repository

Installation

YunoHost installs as a full OS image or on top of an existing Debian installation:

# Install on a fresh Debian 12 system
# First, download the installation script
wget https://install.yunohost.org/ -O install.sh

# Run the installer (requires root access)
sudo bash install.sh -a

# Alternative: flash the ISO image to USB and install like any OS
# https://yunohost.org/#/install_on_hardware

For a quick test, you can also run YunoHost in a Docker container:

# Run YunoHost in Docker for evaluation (not recommended for production)
docker run -d \
  --name yunohost \
  --privileged \
  --volume /sys/fs/cgroup:/sys/fs/cgroup:rw \
  --volume /opt/yunohost:/home/yunohost \
  --publish 80:80 \
  --publish 443:443 \
  yunohost/yunohost:latest

After installation, access the admin panel at https://your-server-ip/yunohost/admin and the user portal at https://your-server-ip/.

App Management

YunoHost uses its own packaging system (based on Debian packages and shell scripts) rather than Docker. Each app in the catalog is installed via the web admin panel or the command line:

 1
 2
 3
 4
 5

# Install apps via CLI
sudo yunohost app install wordpress    # Install WordPress
sudo yunohost app install nextcloud    # Install Nextcloud
sudo yunohost app install matrix       # Install Matrix/Element chat server
sudo yunohost app install vaultwarden  # Install Vaultwarden password manager

# List installed apps
sudo yunohost app list

# Update all apps
sudo yunohost apps upgrade

This approach means apps integrate more deeply with the system — they share the same SSO, benefit from the same backup system, and are managed through a unified package manager.

FAQ

Can I run CasaOS, Umbrel, or YunoHost on a Raspberry Pi?

Yes, all three support Raspberry Pi hardware. CasaOS runs on Raspberry Pi 3 and 4 with as little as 1 GB RAM. Umbrel officially supports Raspberry Pi 5 with at least 4 GB RAM. YunoHost runs on Raspberry Pi 3, 4, and 5 with a dedicated SD card. For the best experience on a Pi, use Raspberry Pi 4 with 4 GB or Raspberry Pi 5 with 8 GB.

Do I need to wipe my existing Linux installation to use these platforms?

CasaOS installs on top of an existing Linux system without affecting your current setup. YunoHost can also install on a fresh Debian installation alongside other services. Umbrel recommends a dedicated installation but can run on x86 systems via its install script. Only YunoHost as a full OS image requires a clean disk.

Can I run Docker containers alongside these platforms?

CasaOS and Umbrel are Docker-based, so you can run additional containers on the same host using standard Docker commands. YunoHost uses native Debian packages rather than Docker, so running Docker alongside it works but is not the primary workflow — you would manage Docker containers separately from YunoHost’s app system.

Which platform is best for beginners?

CasaOS has the lowest barrier to entry — a single install command and a visual dashboard make it ideal for first-time self-hosters. Umbrel is also beginner-friendly with its app store and polished interface. YunoHost has a steeper learning curve but offers the most guidance through its documentation and community forum.

Can I migrate from one platform to another?

Direct migration is not supported because each platform uses different app packaging and data storage approaches. However, since most apps store data in standard formats (SQLite databases, file directories), you can manually export data from one platform and import it into the corresponding app on another. Always back up before attempting a migration.

Do these platforms handle SSL certificates automatically?

YunoHost includes built-in Let’s Encrypt integration and automatically provisions SSL certificates for its dynamic DNS domains. CasaOS and Umbrel require manual SSL setup — you typically need to configure a reverse proxy (like Caddy or nginx) and use certbot for Let’s Encrypt certificates.
