How it works

Seedloader is a fast, visual seed explorer for Minecraft. It uses a deterministic noise function to generate biome layouts and structure positions from any seed. Great for visualization and planning your next world.

Supports Java / Bedrock versions as simple labels (no version-specific gen).
Overworld, Nether and End dimensions toggle color palettes.
Features panel lets you toggle biomes, terrain shading, grid lines, and structures.
Structure buttons control which fake structures are rendered on top of the map.

Controls

Seed: Accepts numeric or text seeds. Text is hashed into a 32-bit signed integer similar to Minecraft.
Biome scale: Controls biome “blockiness”. Low values give noisy small biomes, high values give broad regions.
Render quality: Affects sampling step size. Lower values are slower but sharper; at high zoom the map renders roughly block-per-pixel.
URL hash: Current seed, version, dimension, center and zoom are encoded into #seed=...&platform=...&dimension=...&x=...&z=...&zoom=... so you can bookmark or share the view.

Notes

Seedloader is not affiliated with Mojang. This is an independent tool using noise-based generation for seed visualization.
