Host a Garry's Mod server for your friends
Garry's Mod is on our roadmap, not in the launch catalog yet. Votes from the waitlist decide how fast it ships.

- 2-4 GB
- Default server ports
- 27015
- Protocol
- UDP (TCP for RCON)
- Server OS
- Windows, Linux
- Typical group

You never forward any of these. The agent connects outward to our relay; the game's ports stay on your machine.
Why host Garry's Mod with Multiplayer Rally
The original sandbox server culture: gamemodes, addons, and two decades of community servers. The server is light and the recipe is straightforward, so votes move it up fast.
- Light server: Garry's Mod fits comfortably on most gaming PCs. Plan on 2-4 GB of free RAM.
- Runs the official Garry's Mod server on Windows, Linux. We download it from the publisher and keep the runtime patched.
- Your Garry's Mod world stays set up between sessions. The app handles restarts, updates, and the relay link so the squad can drop in whenever you're online.
How hosting Garry's Mod works
- Step 01
Install Multiplayer Rally
One Windows app. It installs and manages the Garry's Mod dedicated server for you. No command line, no config files.
- Step 02
Pick Garry's Mod
We set the ports, the settings, and the restart schedule. You pick the world name and who's allowed in.
- Step 03
Share your link
You get one address your friends paste into the game, and they're in. Nothing to install on their side, no port forwarding on yours.
Garry's Mod hosting questions
Plan on 2-4 GB of free RAM for a friend-group server. Your PC needs that on top of whatever else it's running; the app checks before installing.
27015 (UDP (TCP for RCON)). With Multiplayer Rally you don't forward any of them: the agent makes an outbound connection to our relay, and your friends connect to the relay address.
Yes, that's the whole point. The agent on your PC makes an outbound connection to our relay, so you never touch your router. Your friends connect to the relay address and the traffic is tunneled to your Garry's Mod server. Nothing is exposed to the open internet.
Yes. Each player needs their own copy of Garry's Mod to join your server. We host the server side; the game itself comes from the store like always.
Garry's Mod is on the roadmap behind the launch catalog. Joining the waitlist and naming it is a vote: demand decides the order we ship recipes.
Your PC is the server, so the world is offline until you turn it back on, then it's right where you left it. The agent restarts Garry's Mod for you automatically. An always-on managed tier on our hardware comes later.
