Cubiomes Seed Finder Library
What Cubiomes Seed Finder Library is
Cubiomes Seed Finder Library is a standalone C library for building tools that search Minecraft Java Edition seeds and generate large-scale biome maps. Given a seed, it can identify the biome at a block position, or generate biome data across an area or volume; the area function can be faster than checking positions individually. Its structure functions locate generation attempts and assess whether positions are viable based on biomes. Other functions estimate or find world spawn, iterate through stronghold positions, and search 48-bit seed bases for arrangements involving multiple structures. Search results can be saved and loaded. The library supports Java Edition generation, with examples for Minecraft 1.18 and references to layered generation through 1.17. Developers can build a static or dynamic library with make and link it into C programs with GCC. It is intended for fast custom seed-finding applications and large-scale map viewers with minimal memory use. C familiarity is expected, and knowledge of biome generation is helpful. Cubiomes is MIT licensed and available for Linux, macOS, Windows, and self-hosted use. It does not generate blocks, so some structure checks may be false positives when surface height affects generation; a complete 48-bit search can take days or weeks. A graphical companion, Cubiomes-Viewer, is suggested for people who prefer not to code.
Who it suits
Cubiomes suits developers building custom Minecraft Java Edition seed finders or large-scale map viewers, especially those comfortable with C. Familiarity with biome generation can help, while people who prefer a graphical tool can consider the separate Cubiomes-Viewer application.
What it does well
- Checks biomes at positions and generates biomes across areas or volumes.
- Includes structure viability, spawn, and stronghold functions.
- Supports multi-structure searches across 48-bit seed bases.
- Search results can be saved and loaded.
- MIT licensed for use, modification, and distribution.
What to know first
- Requires C familiarity to use as intended.
- Some structure results may be false positives due to surface height.
- Searching the full 2^48 seed space can take days or weeks.
Limits
The library does not provide block-level world generation, so structure positions affected by surface height can be false positives. Searching all 2^48 seeds can take days or weeks.
Getting started
- Open the project website on GitHub.
- Build a static or dynamic library with make.
- Link the library into a C program with GCC.
- Use the library's biome, structure, spawn, or seed-search functions.
Verdict
Choose Cubiomes if you are building a C-based Minecraft Java Edition seed search or map-generation tool and want biome and structure functions in a library. Look elsewhere if you want to avoid coding, or if your structure checks require block-level terrain generation; the README points non-coders to Cubiomes-Viewer.
Questions
Is Cubiomes free?
Yes. It is free and open source under the MIT license.
Which platforms does it support?
It is listed for Linux, macOS, Windows, and self-hosted use.
What does the library do?
It mimics Minecraft Java Edition biome and feature generation for seed-finding applications and large-scale map viewers.
Does it search Minecraft seeds?
It includes functions for searching 48-bit seed bases, including multi-structure arrangements, and can save or load search results.
Does it generate complete terrain blocks?
No. It does not provide block-level world generation, which can leave false positives for structures that depend on surface height.
Can I use it without coding?
Cubiomes is a C library. Its README points people who do not want to code to the separate graphical Cubiomes-Viewer.
