What's where
- Seed bar (above the map) — edition & version, seed, dimension, biome height, Goto, Share; copy button in the seed field; ⋯ holds sign-in, export / import
- Structures / Biomes tabs — choose markers, highlight biomes
- Finders tab — Seed Finder (multi-condition search), Structures (nearest, with distance and direction), Ores, Spawners & Huts, Seed Checker
- Layers tab — map tools (Grid, Measure), overlays (Slime Chunks, Stronghold Rings, Terrain Shading) + settings
- Map, bottom-right — scale "1px = Nm" + ruler
- URL hash auto-syncs seed + cam + zoom + filters; copy from address bar to share
Seed Finder Tips
Use rare constraints first, then add common structures around them.
Strongholds
- 128 total, in 8 rings. Ring 1 starts around 1,280-2,816 blocks from spawn.
- Strongholds do not generate under Ocean biomes.
Structures
- Many structures have biome rules: Witch Hut needs Swamp, Igloo needs Snowy, Desert Pyramid needs Desert.
- Village placement is grid-spaced; two villages of the same type rarely sit in adjacent chunks.
- Pillager Outpost cannot be too close to a Village.
- Ocean Monument needs Deep Ocean around it.
- Ancient City, End City, and Nether Fortress require the matching dimension.
- Trial Chamber requires 1.21+, Trail Ruins requires 1.20+, and Abandoned Camp requires 26.3+.
Biomes
- Lush Caves, Dripstone Caves, Deep Dark, and Sulfur Caves (26.2+) are underground-only. Search at Underground or Y -51.
- Mushroom Fields is rare; expect longer searches.
- M biome variants are rarer than their base biome.
Speed tip: start with the rarest criterion and radius 2k-4k. If 30s returns 0 hits, the rule is probably too strict.
Strongholds
- Three strongholds sit near spawn, each beside a village, the first usually 600-1,000 blocks out. More are scattered across the world: about one in four 3,200-block grid cells has one.
Structures
- Biome and grid rules are similar to Java, but fewer structure types are available.
- Trail Ruins needs 1.20+, Trial Chamber needs 1.21+, Ancient City needs 1.19+, and Abandoned Camp needs 26.50+.
- 26.0-26.52 share the same structure RNG; 26.50+ adds Dappled Forest and Abandoned Camps on top.
- Witch Hut needs Swamp, Ocean Monument needs Deep Ocean, and Pillager Outpost is not near Village.
- Buried Treasure appears on Beach and Stony Shore only.
Biomes
- 3D biome searches use the same Y-height idea as Java.
- Bedrock biome layout differs from Java; do not expect identical seeds across editions.
Speed tip: Bedrock searches check each seed with the Bedrock structure generators, so they run somewhat slower than Java. Start with the rarest criterion and a 1k-2k radius.
Conditions
Every condition is measured from a point: fixed X, Z or the seed's spawn (Overworld). Biome takes a set of biomes and a rule: has any of them, has all, has none, or only them. Structure cluster wants several structures inside one circle, e.g. 2 Swamp Huts within 128 blocks of each other. Terrain height checks the median ground height around the point, e.g. spawn between Y 100 and 320. Island wants the land at the point ringed by ocean within the radius. The chips above the conditions load ready-made searches (Speedrun, Quad witch hut, …).
Good starter searches (both editions)
Village near spawn · Ruined Portal + Village ≤ 1k · Pillager Outpost + Mansion ≤ 3k · Ocean Monument + Shipwreck ≤ 1.5k · spawn with no Ocean within 500.
