Apps
Thousands of apps, one click each
Almost 4000 apps, or any Docker image, installed with sensible defaults. And when you want it, full control over ports, folders, variables and network, down to the compose file.
Public beta
Your home server,
without the command line.
Turn any PC into a home server you run from the browser. Free, open source, and built on plain Debian, so you're never locked in.
The demo runs in your browser. Nothing to install.
Why MajaOS
Free, without limits
No licence, no subscription, no cap on disks. MIT-licensed, every line on GitHub.
Never locked in
Plain Debian with ZFS, Docker Compose and KVM underneath. Your pools, apps and VMs keep working without MajaOS.
Changes you can undo
Lose the connection after a network change and it rolls back by itself. An update that doesn't start puts the old version back.
An AI that knows your server
Ask in plain words, and let it do the work. With a local model, nothing leaves your home.
Storage
Know exactly which disk is which
MajaOS draws your case and puts every disk in its bay, so a failing disk is never a guess. Leave a spare in, and a rebuild starts by itself when a disk fails.
Virtual machines
Any operating system, next to your apps
Home Assistant, Windows 11, OPNsense or anything that boots. MajaOS picks hardware the installer understands, and you can still pass through your graphics card or a USB stick.
AI
Ask your server, in plain words
The chat can check and run almost everything in MajaOS for you. Use a model on your own graphics card (Ollama, LM Studio, llama.cpp, LocalAI) or Claude, or connect Claude, Cursor or VS Code to your server.
Example
Is everything okay with my disks?
storagedisk_details
Yes. All 10 disks are healthy and the pool tank is online; its last check, 9 days ago, found no errors. sdc is asleep, so I didn't wake it to read its temperature.
Restart Jellyfin, it feels slow.
app_action
Done. Jellyfin restarted and is running again.
Taken care of from day one
Backups, all three
An app for your PCs and Macs that pairs with a code, the server to any cloud encrypted, and snapshots of your apps and VMs.
An installer without questions
Pick a language and a disk. The rest, from Debian to ZFS and Docker, sets itself up.
Safe on day one
HTTPS, two-step sign-in and protection against password guessing, before you change a single setting.
Install
From USB stick to dashboard in about half an hour
- Write the installer to a USB stick and boot the PC from it.
- Pick your language and a disk for the system.
- Open the address it shows, and create your account.
