Valheim Dedicated Server Guide — Self-Host or Rent in 2026

Self-host or rent?

Everything below assumes Valheim 1.0. The choice is really about uptime and networking:

• Self-host if you play in scheduled sessions, have a spare machine that can stay on, and are comfortable forwarding ports. Cost: nothing but electricity.
• Rent if your group spans timezones, you want the world always on, or you want a panel that handles ports, updates and backups. Cost: a monthly fee.

Setting up the free dedicated server

The dedicated server tool is a free, separate install — on Steam it lives under Library → Tools → Valheim Dedicated Server, and on a Linux box you can deploy the same thing with SteamCMD.

1. Install the tool and open the install folder.
2. Edit the launch script (start_headless_server.sh on Linux, .bat on Windows). It takes flags for the server name, the world name, a password and the port (2456 by default).
3. Launch it headless — no game client — and read the console output until it reports the world is loaded and listening.
4. Join from the game’s Join Game screen, either by IP or from the community server list.

Flag names and defaults change between releases. Read the script that shipped with your install instead of trusting an old tutorial — that is the single most common reason a copied command line fails.

Ports and networking

Forward UDP 2456 plus 2457 and 2458 to the server machine. If your group cannot see the server, the usual culprits are: ports forwarded to the wrong internal IP, a double NAT (router behind router), or ISP-level blocking of the game port. Rented servers skip all of this — the panel maps the ports for you.

Crossplay and join codes

With crossplay enabled, the server produces a join code, which is how Xbox, PlayStation, Switch 2 and Microsoft Store players get in. Two rules apply: crossplay must be on at the server level, and every player must be on the same game version. See the crossplay guide for the platform-by-platform detail.

Backups

Worlds live in the IronGate/Valheim worlds folder — LocalLow on Windows, .config/unity3d on Linux. Copy both the .db and .fwl files before any risky change: a mod install, a version update, a map edit. Most hosts run automated backups, but confirm the retention period before you depend on them.

Renting a Valheim server

If you would rather not manage a machine, these are the hosts Valheim groups most often shortlist. The table is a starting point for research, not a recommendation ranked by price — always confirm current specs and pricing on the host’s own site.

Valheim server hosts compared

Host	Best for	Panel & mods	Check before you buy
Host Havok	Small groups that want a Valheim-focused host with responsive support	One-click installs for popular Valheim mods, plus world-file upload so you can move an existing save in	Plan RAM against your player count, and whether backups are included
BisectHosting	A low-cost first server, especially modded worlds	Long one-click modpack list and help installing mods you bring yourself	Renewal price versus the advertised first-term price, and the refund window
GTXGaming	Groups spread across regions that care about hardware and location choice	Panel with mod support and a choice of server locations	That the location you pick actually covers every player, not just the host
Nitrado	Players who already rent other games on the same account	Preconfigured Valheim templates rather than manual file editing	Contract length and auto-renewal terms before the first payment
Shockbyte	The cheapest route to a world that is always online	Panel with mod and plugin support	Support response times and the exact backup policy

Plans, hardware and prices change often, so this table is a shortlist for research rather than a quote — confirm current specs, regions and pricing on the host’s own site before paying.

What to compare before you pay

• Player slots versus RAM — the two are not the same thing, and an ageing world needs more memory than a fresh one.
• Region coverage — a server on the wrong continent adds latency nobody enjoys.
• Backups and restore — how many copies, how far back, and whether restoring is self-service.
• Renewal price — introductory pricing is common; check what month two costs.
• Panel quality — can you change the world seed, upload a save, and switch versions without a support ticket?

Keeping a server healthy

• Update on the same day as the group, not before — version parity is what makes crossplay work.
• Watch the log after any mod change; most breakage is visible there before it is visible in game.
• Snapshot before big builds. Recovery from a two-day-old backup hurts far less than rebuilding a hall.
