How to make a Terraria server: with and without mods

Terraria is most fun with friends. With your own server the world is always there, including for Calamity and other mods.

Vanilla or tModLoader?

For the normal game, pick a Terraria server. For mods like Calamity or Thorium you need tModLoader, which is a separate plan with us (“Terraria with Mods”). All players then need tModLoader and the same mods.

How much RAM?

  • Vanilla: 2 GB for a small world with friends, 4 GB for a large world with up to about 16 players.
  • With mods: 4 GB for a few small mods, 6 GB and more for big mods like Calamity.

Step by step at Navoryx

  1. Order a Terraria or Terraria with Mods server.
  2. Before the first start, set up the world: in the Panel under Startup, the variables World Name, World Size (1 small, 2 medium, 3 large) and Difficulty.
  3. Start the server. The world is generated on the first start, which takes one to two minutes.
  4. In Terraria: Multiplayer → Join via IP, pick a character, enter IP and port.

Protect the server with the Password variable so only your friends get in.
