How to add mods to your Satisfactory server

Mods come from ficsit.app (the Satisfactory Mod Repository). They need the Satisfactory Mod Loader, which the server installs for you along with any mod it depends on. Only mods that have a dedicated server build are accepted.

Back up first. See How to back up and restore your Satisfactory world.

Add a mod

1. Find the mod on ficsit.app and copy its Mod Reference.
2. Enter one or more references, separated by commas, in the ficsit.app mods setting under Settings, then Game Settings, for example RefinedPower, LoadBalancers.
3. Turn Automatic Updates off while you run mods, so that a game update does not outrun the mod loader. While it is off the server stays on its current game version, so turn it on again if players cannot join after a game update.
4. Restart the server. The mod loader and dependencies are downloaded to match the game version the server runs, and are checked again at every start.
5. Alternatively, upload a mod's Linux server build by hand into the FactoryGame/Mods folder in Files. Mods uploaded this way are never touched by the ficsit.app mods list.

Where files go

Open Files and use these places:

• FactoryGame/Mods (inside Files)

Players need the same mods

Everyone who joins needs the same mods and versions as the server.

Check it worked

Once the server has restarted, read the Console. A mod that loaded shows up during startup, and problems show under Errors and Warnings. See How to use the console and run commands and How to add mods, plugins and modpacks.

If the server stops after you add a mod, remove the newest mod or restore your backup. See How to fix a server that will not start.
