Our review
Pros
  • Supports Java 26.3 and Bedrock 26.50, the Wilderness Bound releases
  • Seed finder hunts for chosen biomes and structures inside an area you set
  • Datapack mapper previews custom Java 1.20 and 1.21 overworld generation
  • Nested conditions find features placed relative to one another
  • Quad-hut and quad-monument generators speed up searches for rare layouts
  • Lua scripts and logic-gate helpers build custom filters inside the app
Cons
  • Seed searches run on your own processor and drain phone batteries
  • Spawn estimates can be badly wrong for some seeds, by the site's own note
  • Bedrock structure predictions are less certain than Java ones
  • Java Edition only, and the latest release stops at 1.21 (Winter Drop)
  • No new release since November 2024, so 2025 and 2026 drops are missing
  • macOS is not formally supported; builds target Windows and Linux
