Seed Finder.
Search the real generation math for seeds that fit you: a biome at an exact coordinate, structures within a radius (or a cluster of them), a climate channel in a value band, the biome at the world's spawn - or any combination. Every seed is tested by the same WebAssembly engine that draws the map, right in your browser, and the live preview shows the seeds as they are tested.

Build a query on the left: stack biome, structure, climate and spawn conditions, each with its own center and radius. A radius of 0 tests the exact coordinate, so "Plains at 0, 0" is one click away.
