Cubiomes Viewer vs mcseedmap.net

Cubiomes Viewer is a graphical Minecraft Java Edition seed finder and map viewer built around cubiomes. It displays biomes in the Overworld, Nether and End, with zoom controls and toggles for supported structure types. The customizable seed finder applies hierarchical conditions to structure placement, world spawn and area biomes, and includes Quad-Hut and Quad-Monument generators for rare structure searches. Helper logic and Lua scripts can define custom filters within the tool. In a fixed seed, Locations mode checks trial positions against conditions and records matches with information about where each condition triggered. Biome and structure analysis tabs report counts, sizes and positions in an area. The project supports Minecraft Java Edition main releases through 1.21. Its main code is open source under GPLv3, and downloads are available for Windows and Linux. The project says macOS and other non-PC platforms are not formally supported. It warns that estimates for some structures in Minecraft 1.18 and later can be inaccurate when terrain prevents generation.
