Terraria Server Hosting for Southeast Asia

Vanilla or tModLoader: pick before you generate the world

A Terraria server runs in one of two shapes. Vanilla is the plain game as Re-Logic ships it. Everyone who owns Terraria can join, nothing needs installing, and the server starts in seconds. tModLoader is a separate program that loads mods, and it is the version you want if your group plays with Calamity, Thorium, magic storage, quality of life packs, or anything else from the mod browser. Both run fine on the CraftRift Terraria plan, and you choose which one your server boots from the CraftRift control panel.

The important part is that the two are not interchangeable once a world exists. A world generated by tModLoader with mod content in it will not open on a vanilla server, because the vanilla executable has no idea what a modded ore or a modded chest is. Going the other way is friendlier: a vanilla world usually loads on tModLoader, which is why groups who think they might add mods later often start on tModLoader from day one. Decide this before your first world, not after your first house.

Every player also needs the same tModLoader version and the same enabled mod list as the server. If one person has an extra mod or an older build, they get kicked at the connect screen with a mismatch message. The fastest fix is to post your exact mod list somewhere the group can copy, then have everyone subscribe to the same collection. When you change a mod on the server, tell people to update too, and restart the server from the panel so the new files load cleanly.

How your friends actually join

Terraria does not use a server browser. Players join by typing an address, which means the only thing you need to hand out is the server address and port shown in the CraftRift control panel. Open the server in the panel, copy the address, and send it to your group. In Terraria they pick a character, choose Multiplayer, then Join via IP, paste the address, and enter the port when asked. If you set a server password, they type that on the next screen and they are in.

Two small things trip people up. First, the port matters: Terraria defaults to 7777 in its own examples, but your server uses whatever port the panel shows, so copy it rather than assuming. Second, a player who cannot connect at all is usually on the wrong game version or the wrong tModLoader build, not behind a broken server. Check the live console in the panel while they try to join. If nothing appears in the console, their client never reached the server. If a line appears and then they drop, it is a version or mod mismatch, and the console normally says which one.

World size, difficulty, and what 1.5 GB comfortably runs

Terraria asks you two questions when you create a world, and both have a real effect on how the server behaves. Size comes first: small, medium, or large. A small world is compact enough that everyone bumps into each other, which suits a duo or a trio doing a straight run to the end. A medium world is the usual choice for a group of friends, with room for separate bases and enough biomes to keep exploration interesting without endless walking. A large world gives you the most of everything, including the most surface area for the server to hold in memory and the most file to save every time the world ticks over.

The CraftRift Terraria plan is $3 per month with 0.5 dedicated core, 1.5 GB RAM, and 15 GB SSD. That memory comfortably runs small and medium worlds for casual groups of 2 to 10 players, which covers the way most people actually play Terraria: a handful of friends, one shared world, a few hundred hours of building. The CPU and RAM are allocated to your server, not shared out to whoever shouts loudest, so your world does not slow down because someone else on the machine started a big project. Heavy mod packs on a large world are the case where you feel the ceiling, and that is worth planning for before you generate rather than after.

The second question is difficulty, and this one is permanent for that world. Journey mode gives you research, duplication, and sliders for enemy strength and time of day, which makes it the relaxed option and a good sandbox for testing builds. Classic is the standard game. Expert raises enemy damage and health, changes boss behavior, and drops treasure bags. Master pushes further again and gives bosses an extra attack pattern. You cannot convert a Classic world to Master later, so agree with your group first. If you are unsure, Classic is the safe pick, and nothing stops you creating a second world on the same server for a harder run.

Keeping the world you built

A Terraria world is one file, and after a few months of tunneling and building it is the only thing your group genuinely cannot replace. Your server takes daily automatic backups, and in the CraftRift control panel you can restore any of them or download the world file to your own computer. Downloading matters as much as restoring. A copy on your laptop is a copy nobody can accidentally overwrite, and it means you can open the world in single player to check something without touching the live server.

Take a manual backup before anything risky: adding or removing a mod, updating tModLoader, letting a stranger onto the server, or running a world edit tool. If something goes wrong, restoring from the panel takes less time than arguing about who did it. Moving in from an existing world is the same process in reverse. Upload the .wld file through the file manager or SFTP, point the server at it, and start.

Two problems you will probably hit

The first is a world file that has grown large after heavy building. Terraria saves the whole world at once, so a large world stuffed with player-made structures takes longer to write, and you may notice a short stutter on autosave. If that starts bothering your group, the practical answers are to keep the world on small or medium rather than large, to prune abandoned mega projects and half-dug hellevators, and to keep older backups downloaded and off the server so your 15 GB of SSD is holding the current world rather than a museum. Restarting the server on a schedule from the panel also clears the slow creep you get from very long uptimes.

The second is players lagging on distant connections. Terraria is sensitive to latency because enemy hits and player movement are resolved live, so a player far from the server sees rubber-banding and mistimed dodges long before they see a disconnect. Our servers run inside Southeast Asia on low-ping regional nodes, so a group in Indonesia typically sees 10 to 30 ms, Singapore 20 to 35 ms, Malaysia 20 to 40 ms, Thailand 30 to 60 ms, and the Philippines and Vietnam 40 to 70 ms. If one person in the group is much worse off than everyone else, the problem is almost always local: a phone hotspot, a crowded Wi-Fi channel, or a housemate downloading something large. Ask them to test on a cable, and check the health score and crash alerts in the panel to rule out the server before you rule in the network.
