Guides, tutorials, and tips for Valheim server hosting.
Valheim allows 1-10 players per server on every host, so ignore slot counts and compare memory and region. Four hosts, prices read from their own pages in October 2026.
How to make yourself admin, the kick and ban commands that work on a vanilla server, the 1.0 ID change that broke admin lists, and why devcommands is refused on a dedicated server — with the three real workarounds.
Every world modifier, preset and key with its exact server value, the ordering rule, why a modifier you removed can still be in force, and how to reset an existing world.
Player-hosted, a home machine, a VPS or a game host — the real costs and failure modes of each, and how 1.0’s crossplay and patch cadence change the decision.
Two files and a name: where the .db and .fwl live on every platform, where to put them on the server, the password rule that blocks the start, and why characters come along for free.
A Valheim server’s memory tracks your world, not your player count. What the 1.0 server really uses, measured, and a sizing table for 4GB, 6GB and 8GB.
Why the 1.0 update broke modded servers, the five-minute vanilla boot that gets your world back, and how to reintroduce mods without repeating the outage on the next patch.
The new biome only generates where nobody has explored. How to check your map, what to do when the north is already mapped, and how a dedicated server fits the Deep North push.
Console players, a new world version, the Deep North, performance notes with a caveat, and mods on shaky ground — plus the update sequence that keeps a mixed PC and console group from being locked out.
Valheim is crossplay on every platform it sells on. Here is the platform list, how PC and console players reach the same dedicated server, why the join code changes, and what breaks crossplay.
The complete 1.0 dedicated server guide for Linux and Windows: SteamCMD install, every launch argument, the crossplay flag console players need, the password rules that silently stop a server, systemd, updates and admin lists.
