MINECRAFT SEED
MAP.
Render a version-aware biome map, reveal structure candidates, search from any coordinate, and plan routes across the Overworld, Nether, and End.
Read the world before you explore it
A Minecraft seed deterministically controls biome noise and structure attempts. This map runs those calculations in a local WebAssembly worker, so panning, version changes, and structure searches do not send your seed to another service.
Version-aware world planning
Terrain generation changed substantially in Java 1.18, while individual structures arrived across later releases. Choosing the correct version prevents modern features from appearing on legacy maps and preserves the older layered biome generator.
Three dimensions, one route
Compare Overworld destinations, locate Nether travel infrastructure, then switch to the End to plan an End City run. Every result includes exact X and Z coordinates and a ready-to-copy teleport command.
Seeds, versions, and accuracy
How do I find my Minecraft seed?
In Java Edition, use /seed in a world where you have permission. Paste the numeric value here. Text seeds are also accepted and converted with Java’s normal string hashing.
Does the seed map support different versions?
Yes. Choose Java versions from 1.8.9 through 26.2. Always select the version that originally generated the chunks you are checking, especially for worlds upgraded across releases.
Are every structure and biome position guaranteed?
Biome-aware candidates are calculated with Cubiomes. Some post-1.18 structures can still fail Minecraft’s final terrain-height checks, and existing chunks or custom data packs can differ from a fresh vanilla world.
Does my seed leave my browser?
No. The seed engine runs locally in a dedicated WebAssembly worker. The share button only places the settings you choose into a URL.
Can I view the Nether and End?
Yes. Switch dimensions to render their biome maps and show dimension-specific structures such as fortresses, bastions, End cities, and gateways.
Why is Sulfur Caves not shown in Java 26.2?
Sulfur Caves is a new underground biome in 26.2 and is not yet implemented by the current Cubiomes engine. The tool clearly excludes that layer rather than inventing inaccurate locations.
