Minecraft tools
Small, focused utilities built on the same generation code as the seed map. Everything runs in your browser — no accounts, no uploads.
Seed finder
Search random seeds for one with a chosen structure candidate close to the world origin.
Structure finder
List the nearest structure candidates for a seed, with coordinates and teleport commands.
Biome finder
Look up the biome at a specific position in a seed. Requires the WebAssembly generation engine.
Coordinate converter
Convert between block, chunk and region coordinates, and between Overworld and Nether positions.
