Terms of use

Using the map

SeedMapKit helps you inspect Java 1.21.1 terrain, biomes and predicted structure start chunks. Use it to plan exploration, compare locations and keep useful map views.

The tool does not create or modify a Minecraft world, provide a game account or grant access to someone else’s server. Use seed information and world access you are entitled to use, and follow the rules of any server on which you play.

Map predictions

The map supports default Java 1.21.1 worlds. Bedrock, other versions, custom generation and older chunks in upgraded worlds may produce different results.

Structure markers show predicted start chunks, not entrances or full structure outlines. Terrain shows the base landscape; illustrated trees and block-style materials are visual aids rather than exact game placements. The map does not show all caves, fluids, ores, interiors or loot. Check important destinations in-game before relying on them.
