How to Install Mods on Your Factorio Server

How to add mods to your Factorio dedicated server — mod folder, mod-list.json, and mod settings.

Installing Mods

Controls which mods are enabled. Auto-generated on first start:

{
  "mods": [
    {"name": "base", "enabled": true},
    {"name": "some-mod", "enabled": true}
  ]
}

This binary file stores mod startup settings. To configure:

Set up mod settings in your local Factorio client
Copy mod-settings.dat from your local mods/ folder to the server's mods/ folder

All players must have identical mods and versions — mismatches prevent connection
Players can use "Sync mods with server" in the server browser to auto-match
Mod checksums are verified at startup
