Minecraft seed finder

SeedCard Finder · Finder version 1.0.2

Choose the biomes and structures you want, then test a range of seeds with the generation model for your version. Open any match on the map, or save the search and resume it later.

The seeds in our catalogue have been checked in game; finder matches have not. Browse seeds · How we check seeds

Results are model predictions, not in-game checks. Area biome checks sample every 16, 64 or 256 blocks and can miss small patches. Each condition's coordinates are in its own dimension.

1. Choose your world
2. Set your conditions All must match

Condition 1

Count, clustering and biome height

With cluster radius 0, the count covers the whole search area. Above 0, the minimum count must fall within that radius of one match, including the match itself. A biome radius of 0 checks the exact coordinate. A feature biome is checked at the structure's marker X/Z and the selected Y, not across its whole footprint.

How to find a Minecraft seed

Page updated

  1. Choose Java or Bedrock and a supported generation version. The same seed can place structures differently between editions.
  2. Apply a search preset, such as Village near origin or Biome variety, then adjust its conditions. You can combine up to eight conditions.
  3. Set each condition's center, radius and dimension. For biome checks, choose the height to sample.
  4. Choose a starting seed and search limits, then select Find matching seeds. Preview a result or open its seed map before trying it in Minecraft.

Search near spawn or fixed coordinates

The presets start at fixed coordinates X 0, Z 0, the world's origin. This can be far from spawn. To search around each candidate's spawn, choose Offset from estimated world spawn and leave both offsets at 0. Nether conditions divide the estimated Overworld spawn coordinates by eight before adding the offsets.

Combine biome and structure conditions

Every condition must match the same seed. To look for a village and a forest in one area, add a structure condition and a biome condition with the same center and radius. Within a biome condition, All selected biomes requires each chosen biome somewhere among the samples in the area or cluster.

If no seeds match

A finished batch covers only the candidate range it searched. It does not mean your combination is impossible. Try removing one condition, lowering the minimum count or widening the area. Resume saved search checks the next range using the saved conditions; start a new search to use your edited conditions.

What a match tells you

Matches are model predictions. Structure locations can fail to generate in game. Biome checks sample points and can miss small patches; None of the selected biomes does not prove those biomes are absent everywhere. Height, flatness and island checks use approximate terrain. An island match can miss a land bridge. Check promising seeds in the selected edition and generation version.

  • Java: our Java finder accuracy review compared 135 selected Java 26.3 predictions with the game; 133 passed and 2 were partial because terrain heights are approximate. Height, flatness and island conditions use the same approximate terrain.
  • Bedrock: our Bedrock structure comparison checked the Bedrock model's structure locations against the game on nine seeds and corrected it; biomes and terrain in Bedrock searches were not part of that comparison.
  • The research page lists every comparison, with its sample and limits.

A match means the model predicts your conditions for that seed. Nobody has checked it in the game. Open it on the map, then create the world in Minecraft with the same edition and version and look before you settle in. The seeds in our seed catalogue are the ones we have checked in the game.

Save and resume a search

Favorites and search progress stay in this browser. A saved search keeps its original conditions and the next untested seed. Use Export search & favorites to keep a backup or move it to another device. Importing an archive merges favorites and replaces the saved search. Stop search lets you pause the current batch.

Already have a seed?

Use the seed map to explore a seed you already know. The biome finder searches for a biome within that world; the slime chunk finder maps eligible chunks. This seed finder searches candidate seeds for your chosen combination.
