Arma 3 Mod List Builder
Paste Steam Workshop URLs or numeric IDs and build the exact -mod=@x;@y; startup string + an Arma 3 Launcher .html preset, plus ready-to-run Windows .bat and Linux .sh server launchers. Live Steam Workshop metadata fetch (titles, file sizes, last-updated dates) via our server proxy. Detects mods that aren't actually Arma 3 (wrong consumer_app_id) and flags them. Supports both client-side -mod= and server-only -serverMod= per entry. Reorderable list with friendly folder-name editing. Free and saturated only by abandoned 0-2-star competitors.

Where do I put the mod folders?
Inside your Arma 3 server directory — /path/to/arma3server/. Each mod folder must match the name in -mod=. SteamCMD downloads them as numeric IDs (e.g. steamapps/workshop/content/107410/450814997/); you typically symlink or rename to the friendly @CBA_A3 form before launch.
What's the difference between -mod= and -serverMod=?
-mod= mods are seen by both the server AND clients — clients must have the same mods or signature verification kicks them. -serverMod= mods only run on the server (e.g. headless-client mods, RCon helpers, AI mods that don't change client gameplay). Signatures aren't checked against clients for serverMods.
Does the .html preset format work in the Arma 3 Launcher?
Yes — this is the same shape the Launcher itself exports. Drag the downloaded .html file onto the Launcher window to import. Best-effort: if your version of the Launcher rejects it, please report; we'll match it.
My mod shows "(not Arma 3)" — is something wrong?
The Steam Workshop ID belongs to a different game (we check the consumer_app_id from Steam against Arma 3's 107410). Double-check the URL — easy to copy a CS or DayZ workshop link by mistake. Remove and re-add the right one.
Can I import a Steam collection?
Not yet — paste the individual mod URLs from the collection page for now. (The unauthenticated GetCollectionDetails endpoint exists; we may add it later if there's demand.)
How do I get the mods onto my server?
Use SteamCMD: +login anonymous +workshop_download_item 107410 <ID> +quit. Anonymous login works for public Workshop items. Loop the command for each ID. The downloaded folders end up under steamapps/workshop/content/107410/<ID>/ — symlink each into your server root with the matching friendly name.
