Good Terraria mods still run through tModLoader. Whether you want a full content overhaul like Calamity or small quality-of-life fixes, these Terraria mods are how most long-time players keep the game fresh.
If you want those mods online 24/7 for friends, you need a dedicated server, not someone’s laptop. AleForge Terraria server hosting supports tModLoader, Vanilla, and TShock so you can pick the stack that fits your group.

How Terraria mods work
Most popular mods install with tModLoader (free on Steam). Players and the server must run the same tModLoader version and the same enabled mods, or joins fail.
A few older projects ship as standalone mods, but for current multiplayer the default path is tModLoader. For server-side install steps, see our add mods to tModLoader guide and Terraria server types overview.
1. Calamity Mod
Calamity Mod is the flagship Terraria content mod for groups that want a full second campaign beyond vanilla. It adds bosses, biomes, classes, gear, and a long post-Moon Lord endgame, but it is heavier than vanilla, so AleForge tModLoader hosting can keep a Calamity world online for co-op.
2. Thorium Mod
For a 2026 Terraria playthrough, choose Calamity Mod for a full second campaign and long post-Moon Lord endgame; choose Thorium Mod for new progression with bosses, biomes, items, and classes without going full Calamity difficulty. Both can suit multiplayer groups on AleForge when the mod setup is compatible.
| Mod | Best fit | What the page highlights |
|---|---|---|
| Calamity Mod | Groups seeking a larger second campaign | Bosses, biomes, classes, gear, and a long post-Moon Lord endgame |
| Thorium Mod | Friends who want more Terraria without full Calamity difficulty | Bosses, biomes, items, and classes including the bard |
Thorium can stack with other content mods when compatibility allows. Check current tModLoader Workshop notes before mixing large packs.
3. Spirit Mod
Spirit expands exploration with new biomes, enemies, and loot while staying closer to vanilla’s tone than mega overhauls. Good middle ground if Calamity feels like too much and vanilla feels like too little.
4. Terraria Overhaul
Spirit Mod is the better fit for exploration and variety. Terraria Overhaul is the better fit when you want vanilla combat and movement with sharper edges.
Overhaul reworks combat, movement, and world feel (dodges, tree physics, tougher AI, and more). It is less “new campaign” and more “vanilla with sharper edges,” which many veterans prefer for replay runs.
5. Magic Storage
For a major Terraria content mod setup on an AleForge multiplayer server, install Magic Storage first, then add Recipe Browser and Boss Checklist. This starter quality-of-life set keeps storage, crafting, recipes, and progression easier for the whole group to manage without changing balance much.
- Magic Storage: Links chests and crafting into a searchable network, reducing time spent hunting for bars.
- Recipe Browser: Helps players check recipe information during progression.
- Boss Checklist: Helps groups coordinate boss progression and craft lists.
6. Recipe Browser / Boss Checklist / similar QoL
Recipe Browser, Boss Checklist, and similar helpers do not change balance much. They help groups coordinate progression and craft lists. On a dedicated server, enable the same QoL set for everyone so nobody is stuck guessing recipes mid-fight.
7. Cross-mod / themed packs
Before combining Calamity Mod, Thorium Mod, Spirit Mod, Terraria Overhaul, and quality-of-life mods on an AleForge tModLoader server, confirm that the chosen pack is maintained for the current tModLoader build and that every player can install the same setup cleanly. Check current tModLoader Workshop notes before mixing large packs.
Crossovers and themed mods, from large franchises to small sprite packs, can change with tModLoader updates. Confirm compatibility before committing a public server to a niche pack.
Running these mods on a dedicated server
To run tModLoader mods on a dedicated Terraria server with friends, every player and the server must use the same tModLoader version and the same enabled mod list. AleForge Terraria server hosting supports tModLoader, Vanilla, and TShock, so groups can select the server type that fits their world.
- Order a Terraria plan.
- Switch the server type to tModLoader using how to change server type.
- Install and enable the same mods for the server and every player with the tModLoader mod install guide.
- Share the server address and keep the world online for the group.
For admin tools and protection rather than content mods, use TShock. For a pure vanilla world, stay on the base Terraria type.
Start your modded Terraria server
Pick the mods your group actually wants, match versions on every client, and host them on hardware that stays online. When you are ready, spin up Terraria server hosting with tModLoader and get back to the fight.
