Satisfactory Dedicated Server Requirements and Setup Checklist

A Satisfactory dedicated server needs a CPU with strong single-thread performance, at least 4 GB of RAM for a new world (6 to 12 GB as your factory grows) and NVMe storage. To set it up, install it with SteamCMD, open ports 7777 and 8888, then claim it in the in-game Server Manager. If you prefer a ready-made server, our Satisfactory server hosting is online within minutes, with DDoS protection and monthly cancellation. The checklist below covers each step in more detail.

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

Since patch 1.1, two ports are required: 7777 over TCP and UDP (game traffic and the server API) and 8888 over TCP (reliable messaging). Both must be open in your firewall so players and the Server Manager can connect. The old ports 15000 and 15777 are no longer used since 1.0.

Key Configuration

Most settings are changed in the in-game Server Manager; the player limit lives in FactoryGame/Saved/Config/LinuxServer/Game.ini:

• MaxPlayers (Game.ini, section [/Script/Engine.GameSession]): default 4, increase to 8 or 16 (monitor performance).
• Auto Pause (Server Manager): pauses when no players are online. Turn it off for continuous production.
• Auto-Save on Player Disconnect (Server Manager): saves when a 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.
