A world to explore.
Not a world fully simulated.

Java profiles

Java 26.1, 26.2 and 26.3 are supported; 26.3 is the default. Only the Overworld is in scope. Text seeds, older releases and snapshots are not supported. Surface maps are approximate climate projections, not exact terrain or surface heights. Underground maps are biome slices at the selected Y, not cave-passage maps.

A small historical check confirmed 12 selected Java 26.3 village starts in an earlier adapter. It does not establish broader accuracy, layouts or living villagers. New POI types have no independent game validation. Independent vanilla checks for Java 26.1 and 26.2 are pending.

Experimental Bedrock preview

Bedrock reuses a Java 26.3 Overworld biome approximation. It is not a verified Bedrock generator and has not been independently checked against any Bedrock release. Structures, geodes and underground slices are unavailable.

Candidates, not guarantees

Geode attempts may fail. All predicted geode heights are shown regardless of the biome slice, and geode Y is approximate. Structure heights, layouts and safe access are not predicted.

Custom generation, datapacks, mods and upgraded chunks may disagree. A seed does not reveal builds, exploration, remaining resources or living villagers. Biomechart does not promise exact ores, safe routes or farm output.
