An online map viewer that helps you find new Minecraft seeds and locate biomes, structures, slime chunks and other features in your current world.

Chunk Base now has a new Seed Finder app! It works like the map search, with conditions for biomes and structures. Seeds can be previewed right on the page. Hope that takes some pressure off the random button :) Let me know what you think! Jul 31, 2026. Excited to share a new search feature I've been working on.

What is a seed? 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.

Free, fast Minecraft seed map — markers verified up to 99% accurate. Biomes, villages, slime chunks & ores for any Java or Bedrock seed. No download.

With the terrain relief view, it's simple to spot flat areas for big builds, dramatic cliffs for cool bases, and hidden valleys if you want something tucked away.

Since those structures are small, often buried, and can be offset 10-20 blocks from the chunk center, you might have to do some searching/digging to find them. The y coordinate isn't shown for every feature. For structures that always generate on the surface or seafloor, this shouldn't be an issue.

Find Minecraft seeds that match your conditions, like structures or biomes near spawn, on Java or Bedrock, and open them directly in the Seed Map. Spawn Chunks Reader provides a quick and easy way to figure out your world's spawn chunks and coordinates by submitting your level.dat file.
