Satisfactory Dedicated Server Setup

Satisfactory's dedicated server runs on Linux and is downloaded via SteamCMD with anonymous login — no Steam account required.

Step 1 — Install SteamCMD

sudo apt-get update && sudo apt-get install lib32gcc-s1 -y
mkdir ~/steamcmd && cd ~/steamcmd
wget https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz
tar -xvzf steamcmd_linux.tar.gz

Step 2 — Download the Server Files

Satisfactory's dedicated server AppID is 1690800. Anonymous login is supported.

~/steamcmd/steamcmd.sh \
  +force_install_dir /home/steam/satisfactory \
  +login anonymous \
  +app_update 1690800 validate \
  +quit

Step 3 — Launch the Server

The launcher script is FactoryServer.sh:

cd /home/steam/satisfactory
chmod +x FactoryServer.sh
./FactoryServer.sh -Port=7777 -BeaconPort=15000 -ServerQueryPort=15777 -log -unattended

Critical: All -Port, -BeaconPort, and -ServerQueryPort arguments must come before -log -unattended. Arguments placed after -log -unattended are silently ignored by the Unreal Engine launcher.

Step 4 — Claim the Server (First Time Setup)

Satisfactory uses a unique server claiming system instead of a traditional admin password set in a config file:

  1. Start the server (it will be in an unclaimed state)
  2. Launch the Satisfactory game client and go to Server Manager
  3. Click Add Server and enter your server's IP and port
  4. The game will prompt you to Claim the server
  5. Set the server name and admin password during the claim process

This is done once. After claiming, your Steam account is the server owner.

Port Requirements

Port Protocol Purpose
7777 UDP + TCP Primary game traffic
15000 UDP Beacon (server discovery)
15777 UDP Server query 
sudo ufw allow 7777/udp
sudo ufw allow 7777/tcp
sudo ufw allow 15000/udp
sudo ufw allow 15777/udp

Updating the Server

~/steamcmd/steamcmd.sh \
  +force_install_dir /home/steam/satisfactory \
  +login anonymous \
  +app_update 1690800 \
  +quit

Run after each Satisfactory game update. Client and server must be on the same version.

Experimental Branch

To run the experimental (beta) branch:

~/steamcmd/steamcmd.sh \
  +force_install_dir /home/steam/satisfactory \
  +login anonymous \
  +app_update 1690800 -beta experimental \
  +quit

Experimental builds may be unstable. Use a separate install directory for experimental if you want to keep a stable copy.
