About ValheimSeed.com
ValheimSeed.com is a free, browser-based Valheim seed viewer and world generator. Type any seed, see the whole world: biomes, boss altars, the trader Haldor, dungeons and their coordinates — before you spend a single hour in game.
Why we built it
When Valheim 1.0 arrived, it rebuilt the far north of every world into the Deep North and changed how new worlds generate. Most seed tools were built years ago and didn't keep up. We wanted a fast, mobile-friendly viewer that follows the current world structure — Deep North in the far north, Ashlands in the far south — and that anyone can use instantly, with no account and nothing to install.
How the generator works
Your seed is hashed into a number that drives every layer of generation: continents and oceans, biome zones by distance and noise, then location placement for bosses, traders and dungeons. The same seed always produces the same map, which is what makes sharing and comparing worlds possible.
Honesty note: our engine produces a deterministic preview that follows the structure of Valheim's 1.0 world generation, and we are continuously tuning it toward game-exact placement. Coordinates from this site are a planning aid — always verify critical locations in game before you commit your base to a spot.
Principles
- Free and open access — no login, no paywall, no limits on how many seeds you check.
- Fast on any device — the whole tool runs in your browser, on desktop and mobile.
- Respect for the game — we are not affiliated with Iron Gate Studio; Valheim is their creation and this is a fan-made utility.
