Create a Satisfactory Server: Setup and Multiplayer (Guide 2026)

This guide shows how to create a Satisfactory dedicated server in OuiPanel, the OuiHeberg game panel, and set it up for multiplayer. It covers the Satisfactory server requirements, claiming the server, inviting friends, ports, backups, importing a save and adding mods.

In regular co-op, everyone gets kicked when the host leaves. With a server, the game stays open without keeping your PC on. Our Satisfactory plans list the available configurations.

What is the maximum number of players?

By default, a Satisfactory game hosts 4 players. On a dedicated server, you can host more with the MaxPlayers setting. Beyond 8 players on the same map with a complex factory, performance can drop depending on the size of the base and the server's power.

For memory, 8 GB of RAM is the minimum. Beyond 4 players, or for a very large late-game factory, 16 GB is recommended. For the CPU, single-core speed matters more than the number of cores.

Satisfactory came out on PS5 and Xbox Series on November 4, 2025, but console players can't join a dedicated server. It's for PC players, who play together across Steam and Epic thanks to crossplay.

Start the server

A Satisfactory server ordered on its own is delivered already installed, with the latest version of the game's server.

1. In OuiPanel, open your Satisfactory server, then Console.

2. Click Start.

3. Watch the log. The first start takes a few minutes, while the server creates its configuration files and prepares the map.

When the console says the server is ready, you can join it. The game updates every time the server restarts.

On an OuiBox

On an OuiBox, create the server first.

1. In the main menu, open OuiBox and click New server.

2. In the "Create new server" window, pick Satisfactory in the "Select a game" list.

3. Name the server, choose its location and resources, then click Create server.

The installation runs on its own. Then start the server from its Console.

Claim the server and connect

The server's address is on the Global View page in OuiPanel, under Main address. It's the address and port to give to your players.

1. Launch Satisfactory on your PC and open the Server Manager from the main menu.

2. Add a server with the address and port from Main address.

3. On the first connection, claim the server: give it a name and an admin password.

4. Create a new game or load an existing one.

Other players add the same server in their own Server Manager. Satisfactory has no public server list: everyone adds it by its address and port.

Configure server settings

The basic setup is done in the game's Server Manager. These are the settings to check first.

• The server name shows up in each player's Server Manager. Pick a name that's easy to recognize.

• The password protects access. Without one, anyone who knows the address can join the server.

• The admin password, separate from the player password, gives access to server administration (saves, advanced settings).

• Auto-pause pauses the simulation when no player is online. To keep the factory running all the time, turn it off with the guide Disable automatic pause on Satisfactory.

Server ports

The game uses one port over TCP and UDP (7777 by default). Since version 1.1, it also uses a second TCP port for reliable messaging (8888 by default). Without this second port, players get stuck on the loading screen.

In OuiPanel, the ports assigned to the server are listed under Configuration › Port Management. If the page shows only one port, open a ticket.

Configuration files

Finer settings are in the Game.ini, Engine.ini and ServerSettings files, in this server folder.

.config/Epic/FactoryGame/Saved/Config/LinuxServer/

Open them from the File Manager with the server stopped. Click the file, edit it, then click Save.

Manage backups

Automatic backups

The game's server creates automatic saves at regular intervals, which you can set in the server settings. It keeps several files in rotation in the SaveGames/ folder: the current save, recent autosaves and the manual saves made from the in-game admin menu.

OuiPanel also backs up the whole server, which protects you from a corrupted file or a wrong move.

1. For an immediate backup, open Backups and click Create backup.

2. For regular backups, open Configuration › Scheduling, create a schedule, then add a Backup task to it.

Make a manual backup before anything risky, such as a game update, adding mods or changing the configuration.

Restore a backup

To go back to a save of the game itself, follow these steps.

1. In Console, click Stop.

2. In the File Manager, open the saves folder and find the .sav file from the date you want.

3. Start the server, then load that save from the game's Server Manager.

The server picks up exactly where the save left off. To go back to a full OuiPanel backup, click Restore next to it on the Backups page.

Import a solo game

To turn a solo game into a multiplayer one, the easiest way is the Manage Saves tab of the Server Manager, which uploads your .sav file to the server.

You can also put the file in the folder below. Open it in the File Manager and drag the file onto the page, or use SFTP with the guide How to connect via SFTP with FileZilla.

.config/Epic/FactoryGame/Saved/SaveGames/server

At the next start, the save shows up in the Server Manager.

Add mods to Satisfactory

Satisfactory Mod Manager

Satisfactory mods are mostly installed with Satisfactory Mod Manager (SMM). This program runs on your PC and connects to the server over SFTP to deploy the mods.

In short, install SMM, add your server with the SFTP credentials from OuiPanel, turn on the mods you want, then restart the server. The guide Install mods on a Satisfactory server with SMM covers each step.

Players install the same mods on their PC with SMM. Multiplayer works with mods, as long as the server and every player have exactly the same ones.

Recommended server mods

Mod	What it adds
SMART!	Advanced building tools: grid placement, copying structures, improved snapping. Useful for large builds.
Refined Power	New power sources, such as solar panels, wind turbines and advanced reactors.
X3 Roads	Extra roads and foundations to keep bases organized.
Linear Motion	Elevators and moving platforms for vertical builds.
Pak Utility Mod	Handy tools, such as creative flight, noclip and teleportation. Useful for admins who inspect large bases.

To share builds between players, also use blueprints with the guide Add blueprints to a Satisfactory server.

Optimize performance

Recommended RAM

Satisfactory uses a lot of memory, especially late in the game, when the factory has hundreds of machines, conveyors and vehicles.

Game stage	Recommended RAM	Details
Early game (Tier 1 to 4, small base)	8 GB for 2 to 4 players	The server uses about 4 to 6 GB.
Mid game (Tier 5 to 7, organized factory)	12 GB for 4 players, 16 GB beyond	Trains, drones and long production chains raise memory use a lot.
Late game (Tier 8 and up, very large factory)	16 GB minimum from 4 players	The biggest bases (turbofuel, large-scale aluminum, nuclear) can use 10 to 14 GB on the server side.

Reduce lag

If the server starts to lag, here is what to look at.

• Limit autonomous vehicles. Trains and drones compute their routes in real time. If you have dozens of them, they're often the first cause of lag.

• Hide conveyors inside closed foundations when you can. The server still computes the transport, but rendering on the players' side is lighter.

• Clean up items on the ground. They pile up and use resources. Check that no overproduction is spilling over somewhere.

• Leave auto-pause on if the factory doesn't need to run offline. The server then saves resources when nobody is playing.

• Keep the game up to date on the server and for players. Coffee Stain Studios regularly releases optimization patches.
