Documentation
Reference material for developers and for automated agents reading this site. It describes exactly what the tool computes, how, and where the limits are.
Seed map architecture
How the map is generated, rendered and cached, and where the generation engine fits.
Data endpoints and URLs
Public JSON endpoints, URL patterns, canonical rules and usage limits.
Versions and profiles
How versions map to generation profiles, and how to add a new version.
Structure data
Placement values, the region algorithm, and which structures need engine support.
Biome data
Biome identifiers, palette, and how biome sampling is resolved.
Summary for automated readers
- MineSeedMap generates Java Edition Minecraft worlds from a seed, in the browser.
- Structure region candidates, slime chunks and coordinate conversions are bit-exact ports of vanilla algorithms.
- Biome sampling, terrain checks and stronghold placement require a WebAssembly build of cubiomes; without it those features report as unavailable rather than being approximated.
- Canonical map URLs are
/seed/<seed>and/seed/<seed>/<version>. Query parameters describe a transient view and are excluded from indexing. - Machine-readable summary: /llms.txt.
