Valheim Seed Map Viewer
Enter a seed above and select Generate map to preview the world.
Maps are generated from the world seed exactly as Valheim does. Biome layout is identical for everyone using the same seed.
How Valheim world generation works
Valheim is seed-based, the same way Minecraft is — and nothing like a fixed, handcrafted world such as Skyrim's Tamriel. There is no single "Valheim map." Every world is generated procedurally from a seed: a short text string you type when creating a world, or a random one the game rolls for you. Feed two players the same seed and they get byte-for-byte the same world — same biomes, same coastlines, same boss locations.
Under the hood, your seed text is converted into a single 32-bit number, and that number drives the entire generator. That means there are about 4.29 billion possible Valheim worlds (232) — comparable to Minecraft's text-seed space. The world itself is a finite disc roughly 10,000 meters in radius, with the ocean dropping off at the edge. You always spawn near the center in a Meadows biome, beside Eikthyr's sacrificial stones.
What the viewer shows
The viewer recreates Valheim's own world-generation algorithm, so the map you see is the map you'll explore:
- Every biome — Meadows, Black Forest, Swamp, Mountain, Plains, Mistlands, Ocean, plus the Ashlands (always to the far south) and Deep North (always to the far north).
- Boss altars — where to summon Eikthyr, The Elder, Bonemass, Moder, Yagluth, The Queen, and Fader.
- Points of interest — the traders Haldor and Hildir, burial chambers, swamp crypts, frost and troll caves, infested mines, and Fuling villages. Toggle each type on or off and click any marker for its exact coordinates.
- Coastlines and rivers — so you can plan a base, a harbor, and your early sailing routes.
- Two views — flat biome colors, or a “Full Terrain” relief view that shades the elevation so mountains and valleys read in 3D.
How to find your world seed
From Valheim's world-select screen, the seed is shown next to each world — copy it and paste it above. If you're starting fresh, roll a Random seed here, preview the world, and reuse the seed in-game to get exactly that map. The seed is also stored in the world's .fwl save file if you ever need to recover it.

Frequently asked questions
How many different Valheim worlds are there?
Roughly 4.29 billion. Your seed text is hashed down to a 32-bit number, and that single number determines the whole world — so there are about 2^32 distinct worlds, similar to Minecraft's text-seed space.
Where do I find my world's seed?
On the world-select screen Valheim shows the seed next to each world. You can also read it from the world's .fwl save file. Paste that seed into the viewer to see your exact map.
Is the generated map exactly what I'll get in-game?
Yes for the world layout — biomes, coastlines, rivers, and where the Ashlands and Deep North sit. Some runtime details (like sea-serpent spawns) are decided while you play and aren't part of the fixed world.
Why doesn't the in-game map already show all this?
In Valheim the map starts black and only fills in as you physically explore. A seed viewer reveals the whole world up front, so you can judge a seed before sinking hours into it.
