Arma Reforger Server Hosting from EUR 2,90/mo

Arma Reforger Hosting, Native Linux

Arma Reforger ships with a native Linux dedicated server binary from Bohemia Interactive. Unlike many game servers that require Wine or Proton, Reforger runs directly on Linux without any compatibility layer. This means lower overhead and more of your allocated resources going to the simulation.

Our guides cover the dedicated server setup, Game Master mode and the best mods and scenarios. Contact us if you need help choosing a tier.

Arma Reforger plans compared

All five plans run the same native Linux server with NVMe storage, DDoS protection, two backups and full FTP access. RAM and disk are what change, and Reforger memory usage scales with player count, mod count and map complexity.

The Lieutenant tier (8GB) handles most active Conflict servers comfortably. Workshop mods also need disk space, because the server downloads and keeps every mod it loads. Moving up a tier later keeps your files.

Setting up config.json, scenarios and Workshop mods

A Reforger server reads one JSON file, passed with the -config startup parameter. Bohemia documents every field on its Server Config wiki page, and the names are case-sensitive. Most of what you will change sits in the game block:

"game": {
  "name": "My Reforger Server",
  "password": "",
  "passwordAdmin": "ChangeMeNoSpaces",
  "admins": [],
  "scenarioId": "{ECC61978EDCC2B5A}Missions/23_Campaign.conf",
  "maxPlayers": 32,
  "visible": true,
  "mods": [
    { "modId": "ID_FROM_THE_WORKSHOP_PAGE", "name": "Any label" }
  ]
}

The name is what the server browser shows, up to 100 characters. With a password set, players need it to join. passwordAdmin is what you type after #login in the chat (no spaces), and IDs listed in admins can log in without it. maxPlayers sets the slots, and visible set to false keeps the server out of the public browser. If your panel's Startup tab has a field for one of these settings, change it there rather than in the file. If an edit in config.json is gone after a restart, ask support.

Crossplay with Xbox and PlayStation is off by default. supportedPlatforms lists the platforms that can join and defaults to PC only, and crossPlatform set to true adds Xbox and PlayStation to that list. Before you open a modded server to console players, check the platform notes on Bohemia's Server Config page.

Bohemia also tells public server owners to keep fastValidation on, which is the default, and to cap the frame rate with -maxFPS at a value between 60 and 120. Without a cap, the server can try to use all available resources. The CPU on our game server plans is shared, so that cap matters. Ask support if you want the cap on your server checked.

Choosing a scenario

scenarioId is the path to a scenario's .conf file with an ID in braces in front. Bohemia ships four official modes: Conflict is the large strategic mode with objectives spread across the map, Capture & Hold is fast and close-quarters, Combat Ops is cooperative, and Game Master is for scenarios your group builds itself. The original Conflict on Everon, which Bohemia's patch notes now call Legacy Conflict, is {ECC61978EDCC2B5A}Missions/23_Campaign.conf, and Game Master on Everon is {59AD59368755F41A}Missions/21_GM_Eden.conf. Update 1.6 (October 2025) added Conflict: HQ Commander for Everon, Arland and Kolguyev as separate scenarios. In those, a player can volunteer or be voted in as their faction's commander and hand out tasks to the squads.

The -listScenarios startup parameter writes scenario paths to the server log, the HQ Commander ones included, but it leaves Workshop scenarios out while a scenario is loaded. For a Workshop scenario, open the mod on the Workshop website and copy the Scenario ID from its Scenarios tab. Keep the mod itself in your mods list. The file takes one scenarioId, so switching from Conflict to Game Master means changing it and restarting.

Workshop mods and load order

Reforger mods come from Bohemia's own Workshop, in the game and at reforger.armaplatform.com/workshop, not from the Steam Workshop. Each entry in mods needs the modId shown on the mod's Workshop page. The name is only a label, and version is optional: leave it out and the server takes the latest version. Players get the mods automatically when they join.

For load order, the part to get right is dependencies. Every Reforger mod declares the mods it needs, and Bohemia's modding docs say a mod cannot load if one of them is missing. The quickest route to a complete list is the one Bohemia describes: enable the mods in the game, open the Mod Manager, switch to the JSON tab and copy the list into the mods array.
