# Best Valheim Server Mods for 1.0: 12 Picks, BepInEx Setup and Who Installs What

**Your game server, free**Ready in 60 seconds, no card.[Create free server](https://1up-servers.com/en/signup/)

The best Valheim server mods for 1.0 are the ones your whole group can actually run: most need every player to install them, a few run on the server alone. This list picks twelve from Thunderstore by downloads, all updated since 1.0, and shows how to load them with BepInEx on our [Valheim server hosting](https://1up-servers.com/en/valheim/) or your own server.

Setting up the server itself? Start with our [Valheim dedicated server guide](https://1up-servers.com/en/blog/valheim-dedicated-server/).

- **Loader:** BepInEx, packaged as BepInExPack_Valheim (5.4.2351 on 13 October 2026).
- **Server only:** Serverside QoL and Expand World Prefabs. They work with unmodded and console players.
- **Admin tools:** Server Devcommands and Upgrade World, on the server and the admin's PC.
- **Both sides:** most content mods. Every player needs the same version, so the server becomes PC only.
- **Where files go:** `BepInEx/plugins` on the server, configs in `BepInEx/config`.

## How we picked these 12

On 13 October 2026 we pulled the full Valheim package list from [Thunderstore](https://thunderstore.io/c/valheim/), the site where Valheim mods are published, and sorted it by total downloads. Then we kept a mod only if:

1. Its latest version was uploaded on or after **9 September 2026**, the day [Valheim 1.0](https://www.valheim.com/news/valheim-1-0-has-arrived-) came out. Older uploads may still work, but nobody has said so.
2. It is a mod, not a library, a mod manager or a modpack.
3. Its README says plainly where to install it (server, client or both). Popular mods that do not say, like Therzie's Warfare, were left out.
4. It is not tagged as AI generated.

We grouped the survivors by where they run, because that decides who in your group can play. Downloads are totals across all versions, so older mods have a head start. Treat them as a sign of trust, not of quality.

## 1. Install BepInEx on the server

Iron Gate's [1.0 FAQ](https://www.valheim.com/support/valheim-1-0-faq) is blunt: "Since we don't have any official mod support, we cannot guarantee that any mods will be functional", and there is no mod support on consoles. Everything here runs on [BepInExPack_Valheim](https://thunderstore.io/c/valheim/p/denikson/BepInExPack_Valheim/), the community loader, with 7.3 million downloads.

On 1up, Valheim runs from Free, but mods start on **Starter**, the first plan with mods (Free and Casual run vanilla servers):

1. Pick the **BepInEx** template when you create the server, or open **Server**, section **Startup**, and set **Mod framework** to **BepInEx**.
2. Restart. At every start, our image checks Thunderstore and installs the newest BepInExPack_Valheim if it changed, then creates `server/BepInEx/plugins`.

Self-hosting? Copy the pack's contents into a clean dedicated server folder; on Linux, start it with the pack's `start_server_bepinex.sh`, as its README explains.

## 2. Upload a mod

1. On the mod's Thunderstore page, press **Manual Download** and unzip it on your PC. Download its **dependencies** too (often Jötunn or YamlDotNet), but not BepInExPack itself.
2. Press **■ Stop**, open **Files** and go to `server/BepInEx/plugins`.
3. Press **+ Folder** and create one folder per mod, open it and press **↑ Upload** to add the `.dll` and any other files from the zip's `plugins` folder.
4. Press **▶ Start**. Each mod writes its settings file to `server/BepInEx/config` on the first start; open the `.cfg` with **Edit** to change it, with the server stopped.

The file manager does not unzip archives or upload whole folders. For a long modlist, the **SFTP access** card on the same page lets FileZilla copy everything in one go. If a mod does not load, `server/BepInEx/LogOutput.log` tells you why.

**Valheim 24/7 from Starter**

Your own Valheim server online around the clock on the Starter plan, €5.00 a month.

## 3. Server-only mods (work with consoles)

These run on the server alone. Players install nothing, which makes them the only kind that fits a crossplay server with PS5, Xbox or Switch 2 friends.

| Mod | Downloads | Latest | What it does |
| --- | --- | --- | --- |
| [Serverside QoL](https://thunderstore.io/c/valheim/p/ArgusMagnus/ServersideQoL/) | 88,397 | 2.3.1, 13 Oct | Framework for a family of server-side quality-of-life mods |
| [Expand World Prefabs](https://thunderstore.io/c/valheim/p/JereKuusela/Expand_World_Prefabs/) | 159,924 | 1.63.0, 11 Oct | Rules for objects being spawned, destroyed and more |

**Serverside QoL** says it is "designed and tested for dedicated servers with vanilla/console clients (e.g. XBox/PS/Switch users)". On its own it "does nothing"; the features come in separate modules from the same author: [AutoStore](https://thunderstore.io/c/valheim/p/ArgusMagnus/ServersideQoL_AutoStore/) puts dropped items into nearby chests, [AutoProcess](https://thunderstore.io/c/valheim/p/ArgusMagnus/ServersideQoL_AutoProcess/) feeds smelters and kilns from nearby containers, and [ContainerSigns](https://thunderstore.io/c/valheim/p/ArgusMagnus/ServersideQoL_ContainerSigns/) labels chests. Upload the base and the modules you want; each has its own `.cfg`.

**Expand World Prefabs** by Jere Kuusela is a power tool: YAML rules that react when objects spawn or are destroyed. Its README asks for one thing: "Install on the server." Use it when you know what you want to change.

## 4. Admin tools (server + your PC)

| Mod | Downloads | Latest | What it does |
| --- | --- | --- | --- |
| [Server Devcommands](https://thunderstore.io/c/valheim/p/JereKuusela/Server_devcommands/) | 1,227,897 | 1.115.0, 26 Sep | Dev commands and utilities for server admins |
| [Upgrade World](https://thunderstore.io/c/valheim/p/JereKuusela/Upgrade_World/) | 385,447 | 1.84.0, 5 Oct | Adds new content to areas you already explored |

**Server Devcommands** lets admins use the game's dev commands on a dedicated server: install it "on the admin client and optionally on the server"; full features need the server copy. Other players need nothing.

**Upgrade World** is the one to know about in 1.0. Iron Gate's FAQ warns that "biome generation will only work properly on areas that have not yet been explored". Upgrade World's [documentation](https://github.com/JereKuusela/valheim-upgrade_world) lists an `upgrade deepnorth` operation that "fully regenerates Deep North biomes and nearby water areas". Commands print what they will touch and wait for `start`. Its own README opens with "Always back up your world before making any changes!": press **💾 Create backup** in **Backups** first.

## 5. Mods every player installs (PC only)

These change items, building or inventories, so the server and every client need the same version. Several refuse a connection on a mismatch. Console players cannot install them, so plan on a PC-only group.

| Mod | Downloads | Latest | What it does |
| --- | --- | --- | --- |
| [PlantEverything](https://thunderstore.io/c/valheim/p/Advize/PlantEverything/) | 2,799,308 | 1.21.3, 25 Sep | Plant berry bushes, mushrooms and more with the cultivator |
| [Epic Loot](https://thunderstore.io/c/valheim/p/RandyKnapp/EpicLoot/) | 2,304,924 | 0.14.13, 24 Sep | Magic items, loot drops and enchanting |
| [ExtraSlots](https://thunderstore.io/c/valheim/p/shudnal/ExtraSlots/) | 1,313,018 | 1.2.19, 12 Oct | Slots for equipment, food, ammo, quick slots |
| [Adventure Backpacks](https://thunderstore.io/c/valheim/p/Vapok/AdventureBackpacks/) | 1,169,534 | 2.3.4, 12 Oct | Craftable backpacks that grow with you |
| [Odin Architect](https://thunderstore.io/c/valheim/p/OdinPlus/OdinArchitect/) | 1,050,591 | 1.8.5, 12 Oct | More building pieces, on a larger scale |
| [MultiUserChest](https://thunderstore.io/c/valheim/p/MSchmoecker/MultiUserChest/) | 783,622 | 0.6.2, 12 Sep | Several players use one chest at once |
| [Spawn That](https://thunderstore.io/c/valheim/p/ASharpPen/Spawn_That/) | 771,324 | 1.2.20, 1 Oct | Configure mob spawners across the world |

What the READMEs say about installing:

- **PlantEverything:** "install the mod on the server (if dedicated) and every connected client". Unmodded players still see what others plant.
- **Epic Loot:** "The server and all players should have the mod and its dependencies installed."
- **ExtraSlots:** the server pushes its slot settings; a player "needs ExtraSlots installed to use its additional inventory UI".
- **Adventure Backpacks:** "Required on Both Client & Server", with a built-in version check.
- **Odin Architect:** "Both Server and Client must have this mod installed."
- **MultiUserChest:** "You will be disconnected if there is a version mismatch or the mod is not installed somewhere."
- **Spawn That:** "Install on both." Clients use the server's configs, so you tune spawns in one place. Its sibling [Drop That](https://thunderstore.io/c/valheim/p/ASharpPen/Drop_That/) does the same for loot tables.

## 6. One mod players can add alone

[Equipment and Quick Slots](https://thunderstore.io/c/valheim/p/RandyKnapp/EquipmentAndQuickSlots/) (1,562,843 downloads, 3.1.3 on 15 September) gives armour its own slots and adds hotkey quick slots. Its README says it is "Client-side installable; does not need to be on servers". Put it on the server too only if you want its balance settings synced for everyone; then the server also needs Jötunn.

## 7. Keep a modded server healthy

- **Patches break mods.** Our image installs the latest Valheim build at every start, because clients refuse a server on another version. Patch 1.0.17 came out on [6 October](https://store.steampowered.com/news/app/892970/view/1845383656396226). After a patch, check each mod's Thunderstore page for an update before you restart.
- **Same versions everywhere.** A shared mod manager profile (r2modman, with 10.6 million downloads, or Gale) keeps everyone on the same files.
- **Back up before changes.** Starter keeps 3 manual backups and Pro 5, and Pro and above add a daily automatic one. Take one before adding or updating a mod.
- **Mixing groups:** crossplay and both-sides mods do not mix. If console friends join, turn on **Crossplay (every platform)** in the **Game** tab and stick to server-only mods; our [join code troubleshooting guide](https://1up-servers.com/en/blog/valheim-join-code-not-working/) covers the rest.

Moving an existing world to a modded server? Upload it first, as in [upload your Valheim world to a dedicated server](https://1up-servers.com/en/blog/upload-valheim-world-to-dedicated-server/), then add mods one at a time. Our guide to [Valheim world modifiers](https://1up-servers.com/en/blog/valheim-world-modifiers/) covers what the panel changes without any mod at all.

## 8. Which plan for a modded server

With prices from [our pricing page](https://1up-servers.com/en/pricing/), **Starter (€5/month)** gives 4 GB of RAM, 20 GB of disk and 3 backups, enough for a few server-only mods. **Pro (€10/month)** gives 8 GB, 60 GB and 5 backups, and is what we suggest for content modlists like Epic Loot or Odin Architect, which add items and pieces the server keeps in memory.

**Valheim 24/7 from Starter**

Your own Valheim server online around the clock on the Starter plan, €5.00 a month.

## Frequently asked questions

Most do. Content mods like Epic Loot, Adventure Backpacks and Odin Architect must be on the server and every client with the same version. A few, like Serverside QoL and Expand World Prefabs, run on the server alone.
