The best tModLoader mods for a group are the ones that work on a server, stay updated and give everyone something to do together. We picked thirteen from the most subscribed on the Steam Workshop, all updated for tModLoader 1.4.4, and explain how to run them on a [Terraria server](https://1up-servers.com/en/terraria/) with friends.

New to Terraria servers? Our [free Terraria server guide](https://1up-servers.com/en/blog/free-terraria-server/) covers vanilla, tModLoader and TShock.

- **Content:** Calamity Mod (with Calamity Mod Music), Thorium Mod, Fargo's Souls Mod.
- **Quality of life:** Magic Storage, Recipe Browser, Boss Checklist, Fargo's Mutant Mod, AlchemistNPC Lite, Quality of Terraria, Census.
- **Server admin:** HERO's Mod and Cheat Sheet.
- **Client only:** Boss Cursor, which each player installs; the server does not need it.
- **On 1up:** tModLoader template, then upload the `.tmod` files from Starter up.

## 1. How we chose these mods

Lists of "top mods" rarely say how they were made, so here is ours. On 13 October 2026 we read the [tModLoader Steam Workshop](https://steamcommunity.com/workshop/browse/?appid=1281930&browsesort=totaluniquesubscribers&section=readytouseitems) sorted by most subscribed, took the first 30 items, and pulled the subscriber count, last update and tags of each from Steam's public Workshop API. A mod made the list if:

1. It carries the **1.4.4** tag, the Terraria version stable tModLoader runs.
2. It was **updated on the Workshop since 1 January 2025**.
3. It is tagged **Both**, meaning it runs on the server and on every client, or it is the one client mod we kept on purpose.
4. It is a mod a group plays with, not a library or a translation patch. Libraries come along when a mod needs them.

Two popular mods missed the cut on rule 2: Ore Excavator (4.8 million subscribers, last updated in August 2024) and LuiAFK Reborn (2.1 million, May 2024). They may still work; they are just not maintained as recently as the rest. Subscriber counts are "current subscribers" as Steam reports them, rounded.

**Why "Both" matters.** tModLoader's own [ModSide definition](https://github.com/tModLoader/tModLoader/blob/stable/patches/tModLoader/Terraria/ModLoader/ModSide.cs) says that for a Both mod, "If a client without this mod connects to a server with this mod, the server will send this mod to the client". So the server's mod list is the one that counts: friends who join get the same Both mods sent to them. All they need is tModLoader on Steam, on the same version as the server.

## 2. Content mods: something new to play together

| Mod | Subscribers | Last update | Workshop size |
| --- | --- | --- | --- |
| [Calamity Mod](https://steamcommunity.com/sharedfiles/filedetails/?id=2824688072) | 9.85 million | 10 Aug 2026 | 404 MB |
| [Calamity Mod Music](https://steamcommunity.com/sharedfiles/filedetails/?id=2824688266) | 9.40 million | 6 Feb 2026 | 697 MB |
| [Thorium Mod](https://steamcommunity.com/sharedfiles/filedetails/?id=2909886416) | 2.34 million | 1 Aug 2026 | 144 MB |
| [Fargo's Souls Mod](https://steamcommunity.com/sharedfiles/filedetails/?id=2815540735) | 2.39 million | 10 May 2026 | 236 MB |

**Calamity Mod** is the most subscribed tModLoader mod by far. Its page lists 27 bosses and 5 minibosses, 2,400+ items and two difficulty settings above Expert. It needs its soundtrack: "this mod REQUIRES Calamity's soundtrack", so **Calamity Mod Music** goes on the server too. Calamity has its own add-ons in the top 30 (Catalyst, Calamity: Wrath of the Gods and Calamity Mod Infernum Mode, each with 2 to 3 million subscribers and updated this summer) for groups that finish the base mod.

**Thorium Mod** is a "Vanilla+" content pack with 2,700+ items and three new classes. One of them suits groups: the Healer, "a special multiplayer-focused class", supports allies with heals and buffs. The page warns: "Make sure you're on the stable version of 1.4.4". That is what a 1up tModLoader server runs.

**Fargo's Souls Mod** adds Enchantment and Soul accessories, new bosses and an Eternity Mode that reworks much of the game. For a Calamity pack, the authors point to an official Fargo's Souls DLC add-on.

Pick one big content mod per world to begin with. Calamity plus Thorium is a common pairing, but every big mod adds loading time and memory, and a first run is easier to debug with one.

## 3. Quality-of-life mods that help a whole group

| Mod | Subscribers | Last update | What it does for a group |
| --- | --- | --- | --- |
| [Recipe Browser](https://steamcommunity.com/sharedfiles/filedetails/?id=2619954303) | 8.44 million | 5 Sep 2026 | Shared favourite recipes |
| [Boss Checklist](https://steamcommunity.com/sharedfiles/filedetails/?id=2669644269) | 8.31 million | 10 May 2026 | Boss progress for everyone |
| [Magic Storage](https://steamcommunity.com/sharedfiles/filedetails/?id=2563309347) | 7.24 million | 22 Sep 2025 | One storage network for the base |
| [AlchemistNPC Lite](https://steamcommunity.com/sharedfiles/filedetails/?id=2599842771) | 5.62 million | 28 Dec 2025 | Seven NPCs selling potions |
| [Quality of Terraria](https://steamcommunity.com/sharedfiles/filedetails/?id=2797518634) | 4.30 million | 23 May 2026 | Shared buffs and crafting |
| [Fargo's Mutant Mod](https://steamcommunity.com/sharedfiles/filedetails/?id=2570931073) | 4.16 million | 10 Apr 2026 | Boss summons for sale |
| [Census](https://steamcommunity.com/sharedfiles/filedetails/?id=2687866031) | 2.61 million | 3 Sep 2026 | Missing town NPCs |

- **Magic Storage** replaces a wall of chests with "a central network to store all your items", searchable from one block, with extra access points anywhere in the world. On a server this is the mod that stops arguments about who moved what. It needs the library SerousCommonLib, as its [build file](https://github.com/blushiemagic/MagicStorage/blob/1.4-stable/build.txt) declares, so upload both.
- **Recipe Browser** shows what you can craft with what you hold, through several steps. Its page notes that "In multiplayer, recipes favorited by other players will also appear in the favorites panel".
- **Boss Checklist** keeps a boss log with spawn items, loot and records such as fight duration, and can post boss despawn messages in chat.
- **Fargo's Mutant Mod** adds the Mutant, a town NPC who "sells boss summons of nearly every mod", plus instant skybridges and hellevators. Its 3.3.5 update lists "Added Multiplayer spectate feature" and "Improved multiplayer performance".
- **AlchemistNPC Lite** adds seven NPCs (Alchemist, Brewer, Jeweler and others) that sell potions and materials, with support for Thorium and Calamity.
- **Quality of Terraria** has "Features specially made for multiplayer", such as sharing infinite buffs and portable crafting stations with teammates. Only some features are on by default; check its config.
- **Census** marks which town NPCs are missing and why, and adds a `TownProgress` command you can run "from the server console".

Two small ones round it off: **Wing Slot Extra** (3.29 million, a dedicated wing slot) and **Auto Trash** (1.98 million, an auto-trash or auto-sell slot). Both are tagged Both and updated in 2025 or 2026.

## 4. Admin mods: run the server without slash commands

| Mod | Subscribers | Last update |
| --- | --- | --- |
| [HERO's Mod](https://steamcommunity.com/sharedfiles/filedetails/?id=2564645933) | 2.12 million | 3 Sep 2026 |
| [Cheat Sheet](https://steamcommunity.com/sharedfiles/filedetails/?id=2563784437) | 2.15 million | 3 Sep 2026 |

**HERO's Mod** describes itself as "a pick and choose server mod": over 25 tools, which you switch on or off and give to different groups, with "full group management with a GUI". On a public or semi-public tModLoader server it does the job TShock's groups do on a vanilla one. Our [TShock commands guide](https://1up-servers.com/en/blog/tshock-commands/) covers the vanilla side.

**Cheat Sheet** is an item, NPC and recipe browser with building tools. In multiplayer you can limit the tools "to only be available to the host", and with HERO's Mod "All the tools will be limited by the permissions assigned to your user". Use the two together, or keep Cheat Sheet off a server where you do not trust everyone.

## 5. Performance and client-only mods

None of the 30 most subscribed tModLoader mods is a server performance mod; the closest is Fargo's Mutant Mod noting improved multiplayer performance. On a server, performance comes down to fewer big content mods and enough RAM.

Some mods only change what one player sees. **Boss Cursor** (4.01 million subscribers, tagged Client) draws arrows towards the boss. The ModSide definition says a Client mod "will not be disabled client-side if the server does not have it", so each player installs it on their own PC and you do not upload it.

## 6. How to run these mods on 1up

1. Create a Terraria server and pick the **tModLoader** template. It runs tModLoader v2026.08.3.0, the stable release of 1 October 2026.
2. Open the **Plugins** tab. The **tModLoader mods** section has an **Upload .tmod** button; it takes files up to 160 MB and switches each mod on in `enabled.json`.
3. If a `.tmod` is larger than 160 MB (Calamity's Workshop items weigh 404 MB and 697 MB, counting files for two tModLoader versions), use **Files** or **SFTP access** to put it in the `mods` folder; it then shows up in the same list with its switch.
4. Restart the server. Changes apply on the next start.
5. Friends start tModLoader on Steam, on the same version as the server, and join by address and port. Both mods are sent to them.

Mod uploads need a plan with mods: **Starter** (€5 a month: 10 slots, 4 GB RAM, 20 GB disk, 3 backups) or bigger, as the [pricing page](https://1up-servers.com/en/pricing/) shows. On Free the tModLoader template runs without extra mods. Large content packs use more memory: the **Statistics** tab shows peak RAM, and Pro has 8 GB if Starter's 4 GB runs short. Back up before adding a big mod to a world you care about; Starter keeps 3 backups.

Keep vanilla and modded worlds apart. A world played on vanilla Terraria 1.4.5 cannot be used in current tModLoader; our [Terraria 1.4.5 server post](https://1up-servers.com/en/blog/terraria-1-4-5-server-what-changes/) explains why, and our tModLoader 1.4.5 status post tracks the port.
