While Satisfactory does not officially support mods, you can use the Satisfactory Mod Manager to install them on your Satisfactory server. You can download the Satisfactory Mod Manager from this link.
Satisfactory servers are in early access in the vanilla game. Adding mods can and most likely will increase the likelihood that you run into crashes and issues. Make sure to backup your save if you don’t want to break your game and lose progress.Not all mods work on servers. You must read each mod’s documentation to ensure it will work on a server.
Select a mod that supports Linux dedicated servers (like Refined Power)
Click install
It is recommended to install mods one at a time to ensure they work properly. Some mods may show a compatibility message - you cannot install these until the developer adds server support.
Each mod will take some time to install depending on the size
Once server installation is finished, switch the source back to Early Access (Steam)
Install the same mods on your PC
All players connecting to the server must also use the Satisfactory Mod Manager to install their mods locally. They only need to install them on their own computers, not on the server.
