How to use the Minecraft Seed Map
Interactive Minecraft seed map for Java and Bedrock: biomes, villages, strongholds, slime chunks and every structure on one map. Enter a seed and explore.
- Enter your seed (number or text) and choose the edition, version and dimension. Press Random for a new seed or load a Java level.dat / world zip.
- Drag to pan, scroll or pinch to zoom. Hover for the biome under the cursor and click a structure icon for coordinates, a /tp command and a Completed checkbox.
- Toggle features in the sidebar, highlight a biome, switch on chunk / region grids, slime chunks, spawn chunks and the world border.
- Right-click (long-press on touch) to drop a marker. Copy a link to share the exact view, or download the map as a PNG.
What the seed map shows
The map draws the biome layout of your world, the same data the game uses to decide what can generate where, and puts every structure on top: villages, strongholds, ancient cities, trial chambers, monuments, mansions, outposts, temples, shipwrecks, ruins, geodes and more. In the Nether it shows fortresses, bastions and ruined portals at Nether scale; in the End it shows End cities, ships and gateways.
Layers add the chunk and region grids, slime chunks, spawn chunks and the world border, and the Highlight biome option dims everything else so a rare biome such as a mushroom field or cherry grove stands out.
Versions and editions
Java Edition is supported from 1.7 up to 26.3, including Large Biomes worlds. Bedrock Edition is supported from 1.18, when its Overworld generator became the same as Java's. Choose the exact version your world was created in: structure rules and biomes changed in 1.13, 1.16, 1.18, 1.19, 1.20 and 1.21, so the wrong version moves things around.
Each structure has an accuracy badge. Exact means the position matches the game; approximate means the structure can fail to generate in-game because of terrain. Structures whose Bedrock placement is not implemented are marked Java only and are not drawn on Bedrock maps.
Questions
Does the seed map work for Bedrock Edition?
Yes for biomes (1.18+ shares the Overworld generator with Java) and slime chunks. Structures whose Bedrock placement is not yet implemented exactly are marked 'Java only' and hidden on the Bedrock map instead of showing wrong positions.
Why does the map show biomes rather than terrain?
It renders the biome map the game uses to decide what generates — the same data that structure and biome finders rely on — and it is fast enough to compute in your browser.
Is my seed sent to a server?
No. All world generation runs in your browser via WebAssembly (cubiomes). Markers and completed structures are stored locally in your browser.
