How to Set Yourself as Superadmin on a Garry's Mod Server

Last updated: May 6, 2026

Superadmin is the highest permission level on a Garry's Mod server — it grants access to every admin command, including banning players and changing server settings. Most admin addons require you to be superadmin before their commands will work. This guide covers setting superadmin in the three most popular admin mods: ULX, SAM, and SAdmin.

Important: Only assign superadmin to players you fully trust. Superadmin grants near-complete control over your server.

Setting Superadmin in ULX

ULX is the most popular free admin suite for Garry's Mod.

Make sure ULX is installed on your server (add it via your Workshop collection and restart the server).
Join your server, or note your SteamID64 if you plan to run the command while offline. A SteamID64 is a unique permanent number that identifies a Steam account.
Log in to the NolimitHost Game Panel, click on your Garry's Mod server, and open the Console tab — this is where you can type commands directly to your server without joining the game.
Run the following command, replacing YourUsername with your exact in-game name:
```
ulx adduser "YourUsername" superadmin
```

You are now a superadmin in ULX. You can verify this by opening the ULX menu with F2 or typing !xgui in chat.

Setting Superadmin in SAM

SAM (Server Administration Manager) is a popular paid admin mod available on GModStore.

Join the server first — SAM requires you to be connected.
Open the Console tab in the Game Panel.
Run:
```
sam setrank "YourUsername" superadmin
```

Note: The superadmin rank cannot be deleted in SAM — it is a protected rank.

Setting Superadmin in SAdmin

SAdmin is another paid admin mod available on GModStore.

Join the server first.
Open the Console tab in the Game Panel.
Run:
```
sa setrank "YourUsername" superadmin
```

Using SteamID Instead of Username

If you are not currently connected to the server, you can target yourself by SteamID64 instead of username. Most admin mods support a variant like ulx adduserid STEAMID64 superadmin. Check your admin mod's documentation for the exact syntax.

You can find your SteamID64 at steamid.io.

Note: Admin rank changes take effect immediately — no restart needed. If a command doesn't work, double-check that the server is running and that ULX (or your admin mod) is installed.
