Valheim Dedicated Server Setup Guide

A dedicated Valheim server keeps your Viking world online 24/7, so your group can sail, build and fight bosses whenever they want — not only when the host is online. Here is how to set one up.

Why dedicated beats in-game hosting

Valheim's built-in "host and play" ties the world to one player's session and PC. A dedicated server runs independently: persistent world, better stability with more players, and no host-migration headaches.

How much RAM and how many players?

• Vanilla, up to 10 players: 4 GB RAM is comfortable.
• Heavily modded or larger groups: 6–8 GB.

Valheim's official server supports up to 10 players; mods can raise that. World size grows over time, so NVMe storage and regular backups matter.

Mods with BepInEx

Most Valheim mods run through BepInEx, installed from Thunderstore. Popular picks add bigger build limits, extra storage, and quality-of-life tweaks. On GGameHost you can install BepInEx and upload mods via the file manager — just make sure every player runs the same client-side mods.

Set it up in 4 steps

1. Pick a Valheim plan sized to your group.
2. Deploy — your server is online in under 60 seconds.
3. Configure the server name, password and crossplay setting; add BepInEx if you want mods.
4. Invite friends via your server address, or use the Join Code where supported.

Moving an existing world

Already have a local world? Upload your .db and .fwl world files via FTP into the server's worlds folder, restart, and your progress carries over.
