What is a Valheim seed viewer?
Every Valheim world is procedurally generated from a seed — a short string of letters and numbers that acts as the DNA of the entire map. A seed viewer (also called a seed map or seed mapper) lets you preview the whole world before you play it: where each biome sits, how far the first boss altar is from spawn, where the merchant Haldor has set up shop, and which direction you should sail for swamp crypts. Think of it as an interactive map for world shopping: paste in any map seed, read the layout in seconds, and instead of committing hours to a random world, shop around for one that fits your group — a big Meadows start, a swamp close to base, or mountains within walking distance.
How to use this world generator
- Find your seed in Valheim's world list (see our guide to finding your seed), or type any new one — seeds are case sensitive.
- Enter it above and hit Generate Map. The map generator draws terrain and biomes instantly; boss altars, Haldor and dungeons appear with exact coordinates, and the list under the map viewer gives you every position as plain text.
- Use the coordinates to plan portal routes, boss runs and trade trips — every distance on the map matches the in-game scale.
- Copy the share link to send the full map to your friends.
Built for the 1.0 Deep North update
Valheim 1.0 rebuilt the far north of the map into the Deep North, with new locations and generation rules that pre-1.0 tools don't show. Our generator follows the 1.0 world structure — Deep North in the far north, Ashlands burning in the far south — so you can plan expeditions into the new content. Read more on the 1.0 Deep North update page, or browse hand-picked seeds if you want a world that's already vetted.
Frequently asked questions
How do I find my Valheim seed?

How accurate is the world map?
The viewer produces a deterministic preview: the same seed always generates the same map, so you can share and compare worlds. The engine is being tuned toward game-exact placement — always verify critical locations in game.

Can I share a seed with my friends?
Yes. After generating a map, copy the share link — it contains the seed as a URL parameter, so anyone who opens it sees the same world instantly.
