Satisfactory Dedicated Server Setup

Server Requirements

A Satisfactory dedicated server needs strong single-thread CPU performance and sufficient RAM. Minimum: 4 GB RAM for a new world. Recommended: 6 to 8 GB for mid-game factories, 10 to 12 GB for late-game mega-bases. NVMe storage reduces load and save times because saves can exceed 500 MB.

Installation via SteamCMD

The server uses SteamCMD app ID 1690800 and supports anonymous login:

steamcmd +force_install_dir /opt/satisfactory \
  +login anonymous \
  +app_update 1690800 validate \
  +quit

Start with ./FactoryServer.sh -unattended. On the first boot, connect via the in-game Server Manager, claim the server and set an admin password.

Opening Ports

Three UDP ports are required: 7777 (game traffic), 15777 (server query) and 15000 (beacon). All three must be open in your firewall so players can connect and the server appears in the server browser.

Key Configuration

Edit FactoryGame/Saved/Config/LinuxServer/GameUserSettings.ini:

• MaxPlayers: default 4, increase to 8 or 16 (monitor performance).
• mAutoPause: true pauses when no players are online. Set to false for continuous production.
• mAutoSaveOnDisconnect: saves when the last player leaves. Keep this enabled.

Save Management

Saves are stored in FactoryGame/Saved/SaveGames/server/. The server auto-saves every 5 minutes by default. Set up a daily backup with tar/cron and remove backups older than 14 days. You can transfer a singleplayer save by copying it to this directory.

Performance Tips

Factory complexity is the biggest bottleneck. Reduce conveyor belt segments by using manifolds, build vertically to limit entity count per area, minimize vehicles with automated routes (use trains instead) and restart the server every 24 to 48 hours to clear accumulated memory.

Can I use mods on a dedicated server?

Yes. Install mods via Satisfactory Mod Manager (SMM) in the server directory. All players must have the same mod versions.

Tip: at HostValues you can rent a Satisfactory server and be online within minutes.
