Pick Terraria (vanilla) to play the game as it is, tModLoader to play with mods, and TShock for admin tools on the normal game. You can switch later in Settings, and we make a backup first. Worlds move between them with a few limits, explained below.
The three types side by side
| Vanilla | tModLoader | TShock | |
|---|---|---|---|
| What it is | Re-Logic’s own dedicated server | Terraria with mods from the Steam Workshop | Vanilla plus admin tools and plugins |
| Players join with | Terraria | tModLoader, free on Steam | Terraria |
| Terraria version | The newest (1.4.5) | 1.4.4 for now | The newest, a little after it’s out |
| Adds | Nothing | Items, bosses, biomes, whole new content | Accounts, groups, bans, protection |
| In-game admin | No, use the Console | No, use the Console | Yes, with groups |
| Starting plan | 2 GB | 4 GB | 2 GB |
Pick vanilla when
- You want the game exactly as Re-Logic made it, on the newest version, the day it’s out.
- Your group is friends who trust each other, so the Console is enough for admin.
- Some players are on phones. They join vanilla servers when their version matches.
Pick tModLoader when
- You want mods: new bosses, classes, items or quality-of-life changes.
- Everyone in your group can run tModLoader. It’s on Steam for Windows, Mac and Linux. Phones and consoles can’t join.
tModLoader runs a little behind vanilla. Today it’s built on Terraria 1.4.4, and its team is working on the 1.4.5 version. Until that’s out, tModLoader worlds don’t have the 1.4.5 content. tModLoader itself updates once a month.
Pick TShock when
- You want real admin in the game: accounts, groups with permissions, and bans you manage from the chat.
- You run a bigger or more public server and want tools to keep it tidy.
- You want plugins, which add commands and features without players installing anything.
TShock follows Terraria’s version, but each new Terraria update needs a new TShock release, which can take a few weeks. Until then, a TShock server stays on the older version, and players on the newest game can’t join.
Switch server type
- Open Settings and change Server type.
- We make a backup of the server first, so you can go back.
- The new game files install from the official source, and the server starts.
- Check which world loads, and read the next section before you play.
The address and port stay the same, so friends join the same way. Only the game they start may change.
Move a world between them
Worlds move with some limits. Always keep the backup we make when you switch.
| From | To | What happens |
|---|---|---|
| Vanilla | TShock | Works. They use the same world files, on the same version |
| TShock | Vanilla | Works. TShock’s accounts and settings stay in the tshock folder, unused |
| Vanilla | tModLoader | Works for worlds from Terraria 1.4.4 or older. A world saved on 1.4.5 shows as (LaterVersion) in tModLoader and can’t load until tModLoader updates |
| tModLoader | Vanilla | The world loads, but modded blocks, items and enemies are lost |
tModLoader keeps its worlds in its own folder, tModLoader/Worlds, apart from vanilla’s Worlds. To use a vanilla world on tModLoader, copy the .wld file there with Files, then choose it in Settings. See backups for both folders.
Once a world has been played on tModLoader and saved in vanilla, the modded parts are gone from that copy. Keep the backup if you might want to go back.
Characters
Characters don’t live on the server. Each player brings their own. tModLoader keeps its characters apart from vanilla ones too. Players can copy a vanilla character into tModLoader with Migrate individual players… in tModLoader’s character list.
A character that played in tModLoader loses its modded items if it goes back to vanilla.
When crossplay arrives
Re-Logic’s Crossplay Phase One update was in final testing in October 2026. When a new Terraria version comes out, vanilla servers get it first. TShock and tModLoader need their own updates after it. If your group mixes types or versions, check that every player can still join before you update.
Questions
What is the difference between tModLoader and TShock?
tModLoader adds mods that change the game, like new items and bosses, and every player needs tModLoader. TShock adds admin tools and plugins to normal Terraria, and players join with the normal game.
Can I use a tModLoader world on a vanilla Terraria server?
Yes, but the modded blocks and items are lost in vanilla. Make a backup first so you can go back.
Can I move my vanilla world to tModLoader?
Yes, if tModLoader supports that world's version. Today tModLoader is on Terraria 1.4.4, so a world saved on 1.4.5 has to wait for tModLoader's update.
Can I switch my Terraria server between vanilla, tModLoader and TShock?
Yes, in Settings, as often as you like. We make a backup first, and the address stays the same.
