Game server
tModLoader Server Hosting
tModLoader runs the big content mods — Calamity, Thorium and friends. Mods cost memory before the first player even joins, which is why the calculator adds overhead for them.
- tModLoader, current stable
- tModLoader mod support
- Full file + console access
- Backups on a schedule you set
- Switch to vanilla Terraria any time

Getting started
Your first hour on Terraria (tModLoader)
1
Connect
Your address and port are on the server page in the panel. Paste the address into Terraria (tModLoader)'s multiplayer screen; if it asks for a port separately, use the one the panel lists — not one from a forum post.
2
Add your content
Supported here: Content mods. Upload through the panel's file manager, or over SFTP for anything large, then restart from the console.

When it misbehaves
Open a ticket from the billing portal — it is tied to your account, so we can find your server straight away. The FAQ covers backups, ports and RAM ceilings.
Terraria (tModLoader) server requirements: RAM and players
Terraria (tModLoader) needs 2 GB before anyone connects. These are the plans our calculator picks for a few common group sizes, using the same numbers as the calculator above.
| Players online | RAM needed | Plan | Monthly |
|---|---|---|---|
| 4 + mods | 3.4 GB | 4 GB | $11.99/mo |
| 8 + mods | 3.8 GB | 4 GB | $11.99/mo |
| 16 + mods | 4.6 GB | 5 GB | $14.99/mo |
Mods, worlds and players
Upload the mods' .tmod files to the server's Mods folder with the file manager or over SFTP, enable them, and restart. Players who join are offered the server's mods, so everyone ends up on the same set.
World Name, World Size, Difficulty, Server Password, MOTD and Max Players (8 by default, up to 64) are on the panel's Startup tab. The tModLoader version is there too.
Big content mods cost memory before anyone joins, which is why the calculator adds overhead when mods are on.
Terraria (tModLoader) server hosting FAQ
How much RAM does a tModLoader server need?
About 2 GB to start, plus about 1 GB for a big content mod and roughly 0.1 GB per player. Sixteen players with mods comes to about 4.6 GB, so the 5 GB plan.
How do I install mods?
Upload the .tmod files to the server's Mods folder, enable them, and restart. Players are offered the same mods when they join.
How many players can join?
Set Max Players on the Startup tab, from 1 to 64 (8 by default).
Can I upload my own world?
Yes. Stop the server, upload the world's .wld file over SFTP, and set World Name on the Startup tab to match.
Can I go back to vanilla Terraria?
Yes. Switch the server to Terraria from the panel. Modded worlds may not load cleanly without their mods, so take a backup first.
Which tModLoader version does it run?
The latest by default. Set a specific version on the Startup tab if your mod pack needs one.
How much does a tModLoader server cost?
From $5.99 a month for 2 GB. Each extra gigabyte adds $3. Terms of 3, 6 and 12 months are 10%, 15% and 20% off, with no setup fee.
Is DDoS protection included?
Yes, on every plan. Traffic is filtered at the network edge before it reaches your server.
Not sure about the size?
The calculator above uses the numbers we measured on our own Terraria (tModLoader) servers — 2 GB to boot, about 0.1 GB per concurrent player, plus 1 GB when mods are on. If you'd rather compare every plan side by side, they're on the pricing page.
