Seed finder
Looking for a world with something interesting near spawn? This searches random seeds for a structure candidate within a distance you choose.
How the search works
The tool generates random 64-bit seeds and, for each one, computes the structure region candidates near the world origin. If one falls within your chosen radius, the seed is added to the results. Everything runs in your browser in small batches, so the page stays responsive and you can stop at any time.
What the results mean
A result means the region grid put a candidate position close to spawn. Minecraft then checks the biome at that position before generating the structure, and that check is not performed here. Open the seed on the map and confirm before starting a world.
Choosing a radius
- A small radius — 200 to 400 blocks — is a genuinely short walk from spawn and takes longer to find.
- Woodland mansions use an 80-chunk grid, so a mansion near spawn is much rarer than a village.
- Widening the radius dramatically speeds up the search.
