How to Add Workshop Mods to Your Arma Reforger Server

How to install Steam Workshop mods on your Arma Reforger server using the Config Editor or config.json.

Arma Reforger mods are automatically downloaded from Steam Workshop — you just add the mod ID to your config.

Using the Config Editor

  1. In the XGamingServer Panel, click Arma Reforger Config
  2. Go to the Mods tab

Search & Add Mods

  1. Type a mod name, author, mod ID, or Workshop URL in the search bar
  2. Results show with thumbnails, names, and IDs
  3. Click Add — the mod is added to your config
  4. Dependencies are automatically resolved

Manual Add

If search doesn't find your mod:

  1. Enter the Mod ID (16-character hex from the Workshop page)
  2. Optionally enter a name
  3. Click Add Mod

Manage Mods

  • Toggle Required on each mod to control whether clients must have it
  • Click Remove to delete a mod from the config
  • Use Import/Export to bulk manage mod lists as JSON
  1. Click Save Changes and restart your server

Via config.json

Add mods to the mods array inside the game block:

"mods": [
    {
        "modId": "597D72161FD1ED1D",
        "name": "My Mod",
        "version": "",
        "required": true
    }
]
FieldDescription
modId16-char hex ID from the Workshop page or mod's ServerData.json
nameHuman-readable label (cosmetic only)
versionPin to a specific version, or "" for always-latest
requiredIf true, clients must have this mod to join

Finding Mod IDs

  • From the Steam Workshop URL: the hex string after the last /
  • From the mod's ServerData.json file
  • Via the Config Editor search (easiest)

Key Setting

In config.json:

"modsRequiredByDefault": true

When true, all mods in the list are required unless individually set to required: false.

Mods Auto-Download

The server downloads mods automatically on startup. Players also auto-download required mods when joining.
