Why host Terraria + tModLoader with Multiplayer Rally
One of the lightest servers in the catalog: vanilla Terraria runs in under a gigabyte. tModLoader support brings Calamity-class modpacks, which is where most of the long-running friend servers live.
- Light server: Terraria + tModLoader fits comfortably on most gaming PCs. Plan on 0.5-1 GB vanilla, 2-4 GB modded of free RAM.
- Runs the official Terraria + tModLoader server on Windows, Linux, macOS. We download it from the publisher and keep the runtime patched.
- Your Terraria + tModLoader 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.

- Step 02
Pick Terraria + tModLoader
We set the ports, the settings, and the restart schedule. You pick the world name and who's allowed in.

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.
Terraria + tModLoader hosting questions
Plan on 0.5-1 GB vanilla, 2-4 GB modded 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.
7777 (TCP). 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 Terraria + tModLoader server. Nothing is exposed to the open internet.
Yes. Each player needs their own copy of Terraria + tModLoader to join your server. We host the server side; the game itself comes from the store like always.
Terraria + tModLoader is in our planned launch catalog. Join the waitlist, pick Terraria + tModLoader as your game, and we'll email you when it's live.
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 Terraria + tModLoader for you automatically. An always-on managed tier on our hardware comes later.
