World Finder

World Finder is a client-side seed map and structure finder for vanilla Minecraft worlds.

Now available on Fabric.

Enter a known seed, or let the mod automatically read the seed in singleplayer, then browse biomes and seed-based structure markers directly in-game. World Finder is built as an in-game ChunkBase-style helper for planning exploration without leaving Minecraft.

World Finder does not bypass server seed protection.
Multiplayer use requires the exact server seed.
