Anonymous Workshop content for 21 dedicated servers.

Commands that are the same for every game

Run setup before adding Workshop content. Replace ITEM_ID with a numeric Steam Workshop file ID, or paste the official Steam Community URL in quotes. A collection uses workshop-collection and the same apply step. AlphaGSM checks that the item, the collection, and every nested item belong to that server's game before it saves them.

./alphagsm myserver mod add workshop ITEM_ID
./alphagsm myserver mod add workshop "https://steamcommunity.com/sharedfiles/filedetails/?id=ITEM_ID"
./alphagsm myserver mod add workshop-collection COLLECTION_ID
./alphagsm myserver mod apply
./alphagsm myserver mod list

mod add records the desired item. mod apply installs it through that game's native loader and remembers the files AlphaGSM owns. To drop one item, run mod remove workshop ITEM_ID and then mod apply. mod cleanup removes owned Workshop state. It does not delete the rest of the server.

Every anonymous SteamCMD module can also stage a download without activating it:

./alphagsm myserver workshop download item ITEM_ID_OR_URL
./alphagsm myserver workshop download collection COLLECTION_ID_OR_URL
./alphagsm myserver workshop list

Staged files live under the server directory at .alphagsm/workshop/content/<game-appid>/<item-id>/. A staged download is not evidence that the game loaded the mod. Use mod add and mod apply when the module has a native loader.

For the Docker manager, start it once with ./alphagsm-docker start, then use ./alphagsm-docker in place of ./alphagsm in the game commands. Both runtimes passed for the 21 games. The commands install the same desired state.

The full provider guide, including manifest mods and plugins, is Install mods and plugins.

What a pass means

These 21 games are the required anonymous Workshop suites in GitHub Actions run 38775144746 on revision 6a446839. Each suite passed its process integration, its Docker integration, and its smoke scenario. A skip fails that CI job. The Workshop support matrix records the fixture, the engine evidence, and the remaining stop or save limitations.

This page does not change the 16 October 2026 support snapshot. Guides for these modules carry an Anonymous Workshop badge that links back here.

Workshop candidates that are not in the 21

These games appear in the Workshop matrix and do not have a pass in both runtimes. Do not treat their download commands as a completed dedicated-server load.

Don't Starve Together, Arma 3, DayZ, Starbound, and Stormworks are outside this no-account campaign. Counter-Strike 2 public hosting still has an account-bound game server login token. Its generic Workshop staging commands do not establish public hosting or arbitrary map activation.
