- Updated to Java 1.21.4 and Bedrock 1.21.50 (Pale Garden)
- Added support for datapacks with custom world height (try JJThunder To The Max)
- Added support for datapacks with version overlays
Add a worldgen datapack:
This datapack mapper is a new experimental feature that may have inaccuracies or even crash, and it can be very slow for some more complex worldgen calculations. It only works with datapacks that use Minecraft's default multi-noise biome generator.
Some examples to try: Terralith, Tectonic, Continents, Litosphere
An online Minecraft seed map viewer and seed finder that helps you locate biomes and structures and find the seeds you want.
It shows a browseable map for a given seed with biomes, terrain estimation, and structures like Villages and Ocean Monuments.
It also can be used to find seeds with specific biomes and structures within a given area.
A Minecraft world seed is a unique number or string of characters that is used to initialize the random generator when creating a new world in Minecraft. This seed determines the layout of terrain, structures, and other features in the world. The same seed generates the same world every time, allowing players to share seeds to explore the same world or create specific landscapes.
A Minecraft seed map is a visual representation of a Minecraft world generated using a specific seed. It shows the layout of terrain, biomes, structures, and other features of the world, allowing players to preview what the world will look like before actually creating it in the game. Seed maps can help players choose interesting or desirable worlds to explore or build in.
Biomes are pretty accurate. Note that the actual shorelines of rivers and oceans do not follow biome boundaries exactly.
Structure positions are accurate to within a few blocks, but some structures may be missing, and there may be structures that are not generated in the game.
Java structure finding is more accurate than Bedrock because there is more information available about the algorithms.
Spawn positions can be completely wrong for some seeds. Java spawn estimation is more accurate than Bedrock.
While using a seed map can reveal the locations of biomes or structures like End Portals without the need for exploration or Ender Eyes, whether it's considered cheating is subjective and depends on the player's perspective. Some players enjoy the challenge of finding structures through exploration, while others prefer to use tools like seed maps for convenience. Ultimately, it's up to each player to decide what they consider fair or enjoyable in their gameplay experience.
Since Minecraft version 1.18, seeds generate the same terrain and biomes on Java and Bedrock editions, but trees, grass and structures will be different.
The site uses modern technologies such as WebAssembly, which are not supported by older browsers. Check that you have updated your browser to the latest version.
Pro tip! If you are more serious about seeds, need high performance and advanced seed finding features, the open source Cubiomes Viewer desktop app is for you.
mcseedmap.net is created by Balázs Farkas ("megasys").
Biomes and structures are calculated from seed using the cubiomes library created by Cubitect and other contributors.
Map colors are from cubiomes, inspired by Amidst.
The browseable map is displayed using OpenLayers.
