Valheim server setup and 1.0 guides

Learn how to set up, join, update, and protect a Valheim dedicated server for the September 9, 2026 1.0 and Deep North release, including existing-world and crossplay guidance.

Valheim 1.0 launches on September 9, 2026 with the completed Deep North biome and crossplay across PC, Mac, Linux, Xbox, PlayStation 5, and Nintendo Switch 2. A persistent dedicated server keeps the same world online for your group even when its original host is away.

Valheim on berrybyte

berrybyte installs the Valheim dedicated server and enables crossplay by default. From the dashboard you can start and stop the server, change its name, password, world, visibility, update behavior, crossplay, and built-in backup schedule.

Your plan includes 10 player slots and starts at $12.95 per month. Open Valheim server hosting to choose a region and start a server.

Which guide should I use?

I already have a long-running world

Start with Valheim 1.0 and the Deep North. It explains explored terrain, backups, and the tradeoff between preserving builds and seeing the complete new biome.

I want a clean world for 1.0

Follow Set up a Valheim dedicated server, then wait until the 1.0 build is live before generating the world you intend to keep.

My group mixes PC and consoles

Keep Enable Crossplay on, then use How to join a Valheim server. Console mod support is not available for 1.0, so plan an unmodded server for a mixed-platform group.

My current server uses mods

Back it up, keep a list of every installed mod, and expect to wait for BepInEx and individual mod updates after 1.0. Do not test the only copy of your world on launch day. Until we port the full BepInEx guide, use Installing BepInEx Mods.

Mods and admin commands

These older guides still live on docs.berrybyte.net until we rewrite them here. Do not treat them as 1.0-verified.

Install BepInEx mods

Upload BepInEx and plugins, match client and server versions, and read the crash log.
