Local calculation
The generation engine runs as WebAssembly inside your browser. It calculates tiles, biome names, spawn estimates, and structure overlays locally. The static app can be served without a seed-processing backend.
This also reduces latency: the work begins as soon as the application and its generator assets are available.
Share only when you decide to
Biomer can keep a map's state in the URL so that a link captures the seed, version, center point, zoom, and layer choices. Copying that URL is an intentional sharing action; nothing is published automatically.
If you do not share the URL, the seed remains in the current browser session.
No account required
There is no registration gate before generating a map. This avoids collecting a profile merely to inspect a Minecraft world and keeps the tool easy to use in a classroom, stream, or a fresh browser session.
Control what you share
The distinction between viewing and sharing matters. You can explore a seed privately, compare several locations, and close the page without creating a profile. If you decide a collaborator should see the same result, send the map link deliberately and use the coordinates and version encoded in that link as the shared reference.
This local-first approach is especially useful for unreleased server worlds, event maps, and personal projects. You retain control over when a seed leaves your device, while still having a convenient way to coordinate when sharing is useful.
