Mods run on the server type Valheim (Mods / BepInEx) – the mod loader BepInEx is already set up there. If you have a regular Valheim server, switch to this type with Switch game. Download your world under Files or create a backup first.
A modpack with a single entry
If your modpack is published on Thunderstore, one entry is enough:
- Open the modpack page on thunderstore.io and copy the Dependency String (e.g.
Author-ModpackName-1.2.0). - Tab Startup variables → ModPack (
V_MODPACK) → enter it, save. - Restart the server. The modpack is installed on startup.
When a new version of the modpack comes out, enter the new Dependency String.
Individual mods
- Download the mod on thunderstore.io (Manual Download) and unpack it on your PC.
- Upload the
.dllfile(s) – usually in the mod'spluginsfolder – under Files into the folderBepInEx/plugins. Many files are easier via SFTP. - Restart the server.
The server creates the mods' settings under BepInEx/config on first start.
Fellow players
Most mods must also be installed by the players – in the same version. The easiest way is a mod manager like r2modman or the Thunderstore App: create a profile, install the same mods or modpack, launch Valheim via the mod manager.
Good to know
- Crossplay (Xbox/Game Pass) and mods don't mix – crossplay is therefore off on this server type.
- If the server no longer starts after a mod, this article helps. Errors are shown in the Console.
- Create a backup before larger mod changes.
