Find seeds by constraints
Stream smart seed candidates through biome, structure, and cluster gates, then keep the worlds that survive the version-specific checks. Results are candidates until verified in Minecraft, Cubiomes, or Bedrock Dedicated Server.
Smart spread: 750 candidates sampled across the signed 64-bit seed space from key "smart" for Java 26.1.2.
When enabled, every selected structure type must have one candidate within that block distance of the others.
When enabled, the selected structures must also sit within that block distance of the required biome sample.
Java biome/structure math is tested against Cubiomes GT for the covered versions. Bedrock uses a cubiomes-bedrock JS prefilter, then BDS can confirm survivor seeds when the verifier is configured.

Run a preset or build a query. Results will appear as soon as a seed passes the gates.
