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
  • Reads seeds from save games and exports the map as an image
  • Shows slime chunks, End islands and more than a dozen structure types
  • Maps very old beta-era worlds that most tools skip
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
  • Support stops at Minecraft 1.17, before the 1.18 terrain overhaul
  • The last release, 4.7, dates from June 2021
  • The project is looking for a new maintainer
