Why Host Your tModLoader Server on Flux?

A modded Terraria playthrough is long: a Calamity run, a Thorium world, a big modpack from pre-Hardmode to the last boss. Hosted from someone's own game, it stops when they log off. A dedicated tModLoader server keeps the world there for the whole group, whoever is playing.

The hard part of a modded server is the mods. Here you search the Steam Workshop from the panel, and every mod comes with everything it requires; players install nothing, because tModLoader downloads the server's mods when they join. New tModLoader releases and mod updates are applied by themselves, after a warning in chat.

Plans are sized by the mods you run, not by slots: Light Mods, Calamity or Big Modpacks, each with dedicated vCores and memory on a decentralized cloud of thousands of independent nodes across 50+ countries.

Worlds with any size, difficulty and secret seed, your own world uploaded, mod configs, a live server console, bans, a file browser and backups, all in the browser. Plans start at $4.49/month, with no contract.

tModLoader Server Features Explained

Mods with their dependencies

A tModLoader server loads a mod only if every mod it requires is loaded too, and it does not fetch them itself. Add a mod from the Workshop search here and the panel shows what it needs and installs it all: Calamity brings its music mod, Magic Storage its library. Switch any mod off without losing it, or upload a .tmod that is not on the Workshop.

Players install nothing

tModLoader sends a server's mods to every player who joins, in the server's exact versions. Your friends start tModLoader, Join via IP, and are playing with the same mods a moment later.

Worlds, configs and a real console

Create worlds of any size and difficulty, Journey included, with secret seeds like For the Worthy or Get Fixed Boi, or upload your own .wld and .twld. Edit each mod's settings file, and use the server's own console from the browser: who is playing, say, kick, ban, save, the time of day.

Updates, saves and backups

The server saves every 10 minutes and on every stop, backs up the worlds, configs and mod list on every start and every 6 hours, and follows tModLoader releases and Workshop mod updates by itself: players get a countdown in chat before it restarts onto them.

Everything you need to set up a tModLoader server, fill it with mods and bring your friends in.

Frequently Asked Questions

Everything you need to know about our hosting service

$4.49/month for Light Mods (1.5 vCores, 3 GB of RAM, 15 GB of storage), $5.49/month for Calamity (2 vCores, 5 GB, 25 GB) and $7.99/month for Big Modpacks (3 vCores, 8 GB, 35 GB). Billing is pay-as-you-go with no long-term contract.
It depends on your mods, not your player count. A few quality-of-life mods (Magic Storage, Boss Checklist, Recipe Browser) fit Light Mods. One big content mod like Calamity or Thorium, with its add-ons, needs Calamity. Several big content mods together, or very large worlds, need Big Modpacks. You can change plan later and keep everything.
In the Mods tab: search the Steam Workshop or paste a mod's link, and press Add. The panel shows what the mod requires and installs it all, then a restart loads them. You can also list Workshop IDs when you deploy, switch mods off without removing them, and upload a .tmod.
No. tModLoader downloads the server's mods for each player when they join, matching the server's versions exactly. They only need Terraria and tModLoader, which is free on Steam.
Yes: add Calamity (Workshop 2824688072) and its music mod comes with it. The Calamity plan has 5 GB, which is what Calamity wants in play. The Calamity team stopped developing the mod in August 2026; its last release is still on the Workshop and loads on the current tModLoader.
They start tModLoader, choose Multiplayer, Join via IP, and type the address and the port from the dashboard, and the password if you set one. Terraria without tModLoader cannot join a modded server.
