What Crafty Seed Map is

Crafty Seed Map is a free web tool for exploring Minecraft Java seeds and locating biomes, slime chunks, and structures. Enter a numeric seed or a text seed, which is hashed using the game’s method, then view the Overworld, Nether, or End. Its nearest-search feature spirals outward from an origin and checks possible structures against biome requirements. Named, colored markers are saved in the browser for each seed; a shareable URL retains the seed, viewport, map layers, and biome highlight. World generation runs locally in the browser, and the seed is not sent to a server. The biome layer uses a WebAssembly port of cubiomes, and structure positions are revalidated against biomes. The map supports Java Edition 1.18.2, 1.19.4, 1.20.6, 1.21.1, and 1.21.3, but not Bedrock Edition. It is described as mobile-first, has pinch-to-zoom controls, and displays no ads. Buried treasure, mineshafts, geodes, desert wells, and end gateways appear only at sufficiently close zoom levels.
