Summary

Cubiomes Viewer is a graphical Minecraft seed finder and map viewer built around cubiomes. It displays biomes across the Overworld, Nether, and End, with zoom controls and toggles for supported structure types. Its customizable seed finder uses layered conditions for structure placement, world spawn, and area biomes. It also includes Quad-Hut and Quad-Monument generators for searches involving rare structure combinations. Helper logic and Lua scripts can be used to make filters inside the tool. For a fixed seed, Locations mode checks trial positions against conditions and records matches with information about where each condition was triggered. Biome and structure analysis tabs show counts, sizes, and positions within an area. The project supports Minecraft Java Edition main releases through 1.21, and its main code is open source under GPLv3. It is free and 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.

Who it is for

Cubiomes Viewer suits Minecraft Java Edition players looking for particular biomes, structures, or spawn conditions in a seed. Its analysis views and custom filters may also suit users who want to inspect areas in more detail.

What is good

Maps biomes in the Overworld, Nether, and End
Searches structure, spawn, and area-biome conditions
Includes Quad-Hut and Quad-Monument generators
Supports Lua filters edited inside the tool
Free and open source under GPLv3

What to know first

MacOS is not formally supported
Some structure estimates may be inaccurate in versions 1.18 and later
Bedrock Edition is not supported

Verdict

Cubiomes Viewer offers detailed seed search and map analysis for Minecraft Java Edition through 1.21, including custom conditions and Lua filters. Its platform support is limited, and some structure estimates may be inaccurate in newer terrain generation.
