Our review
Pros
  • 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
  • In-game seed map and a rotating HUD minimap from the configured seed
  • Locate commands cover biomes, structures, ore veins and chest loot
  • Builds for Minecraft 1.16.5 through 26.3, updated several times a month
Cons
  • 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
  • Java Edition with Fabric only; Bedrock players cannot use it
  • You must know the seed first, or crack it with a separate mod
  • Versions 1.21.11 and older need Java 23 set up in the launcher by hand
