Launch your MU Online server.
Run it like a studio.
MUOS installs the Helix engine on your VPS with a single command, generates a game client with your server's name, and shows you what really happens in your economy and class balance. No remote desktop. No config files. No guesswork.
Paid plans only — try everything first in the demo and in a real sandbox server.

Why MUOS
Running a private server shouldn't feel like defusing a bomb.
Most admins spend their nights in remote desktops and config files. MUOS turns that into a panel, and guesswork into numbers.
Without MUOS
With MUOS
Remote desktop into the VPS to edit .ini and .xml files
Every setting in one panel, applied live
Restart the server — and kick everyone — to change EXP
Rates and drops change while players stay online
Guess why Zen and jewels are losing value
Inflation, sources and sinks — with the cause
Learn about a broken class from angry players on Discord
Win rates adjusted for gear, before anyone complains
Ship a generic client and a text file with your IP
A client with your name that connects by itself
How it works
From zero to an online server in four steps.
MUOS is not a hosting company: your server runs on your own VPS or dedicated machine, and you keep full control of it.
- 1
Create your server in MUOS
Name, experience rate and public address. It takes less than a minute.
- 2
Paste one command on your VPS
Linux or Windows. It installs the MUOS Node — no Docker, no manual database setup.
- 3
Watch it build itself, live
Requirements, runtime, engine, database, game data and health check — every step on your screen as it happens.
- 4
Invite your players
Download the client generated for your server and share it. Your players are one click away from logging in.
The engine
Helix: a modern MU Online engine, built for MUOS.
Helix is the game server behind every MUOS server. It is designed to be administered from a panel — so everything you would edit by hand is a form, a switch or a number, applied while the server runs.
Live configuration
Rates, drops, monsters, maps, items and events change while players are online. No restarts.
Season 6 Episode 3
Classes, maps, events and items of the most played season, ready from the first start.
587 plugins
Events, commands, chat, drops and game rules — switched on and off from the panel, with their settings.
Linux and Windows
Runs on any VPS with 2 GB of RAM. The runtime and the database are installed for you.
Built-in telemetry
Drops, trades, kills and logins feed your analytics automatically, with accounts pseudonymized.
Self-healing
Crashes are detected and the server restarts on its own, with the reason in your log.

NIGHTFALL
The game client
Aether: a game client with your server's name.
Every MUOS server gets its own client. It opens with your server's name on the window and connects straight to your address — your players just download, extract and play.
- Your server name on the game window
- Connects to your server by itself — no IP files
- Change your address in MUOS and the next download follows
- Windows 10 and 11, 64-bit
Intelligence
Every number answers a question.
Dashboards that compare with a baseline, explain the cause and tell you how confident they are — so you decide with evidence, not with the loudest opinion.

Simulation
Test EXP, drop and reward changes on your own data before deploying them.

Your server, your rules
Built so you never lose control.
Your machine, your data
Your game server and its database live on your VPS. MUOS never hosts your game.
No open management port
The MUOS Node only makes outbound HTTPS calls. There is nothing to attack on your VPS.
Roles and audit log
Owner, Admin, Analyst, Game Master and Viewer — and every change recorded with who, when and what.

FAQ
Questions admins ask us.
Is MUOS a hosting company?+
No. Your server runs on your own VPS or dedicated machine. MUOS installs, configures and administers it remotely through the MUOS Node, and gives you the tools to run it.
What VPS do I need?+
Linux (Ubuntu, Debian, Rocky, Alma) or Windows Server, 64-bit, with 2 GB of RAM and 2 GB of free disk to start. 4 GB is recommended for 100+ players.
Which season does Helix run?+
Season 6 Episode 3 — classes, maps, events and items of the most played season.
What do my players need?+
Windows 10 or 11 and the Aether client generated for your server in MUOS. They download, extract and play.
Is there a free plan?+
No. You can explore the complete panel in the demo and administer a real sandbox server freely before subscribing.
Who owns my server's data?+
You do. The game database lives on your machine. MUOS stores the analytics and settings of your organization, isolated from every other customer.
Your server can be online in the next few minutes.
Create it, paste one command, and watch it come alive.
