About chunksout

chunksout is a free, fan-made Minecraft seed map for Java and Bedrock that shows biomes and structures from a world seed.

What chunksout does

Enter a seed and your position, and chunksout draws the world’s biomes and lists the nearest structures with exact coordinates, distance, direction and the matching Nether coordinates. Start on the seed map.

How the map works

World generation runs in your browser as WebAssembly, in a background thread so the page stays responsive. Your seeds are not sent to a server.

How each structure is checked

Every structure type is compared with reference data. A type is Checked and on by default when both precision and recall reach 95%; the other types are offered in Layers as Approximate, off by default, and a type below 50% on either count is hidden. The full counts are public: see how each structure is checked.
