Spec score 8.4 #2 of 35 in Minecraft Seed Finders

What it is

SeedFinder helps Minecraft players locate structures near a world seed and player position, while SeedCracker searches for Bedrock seeds matching structures around supplied coordinates. Listed targets include villages, temples, ocean structures, ancient cities, mansions, portals, buried treasure, mineshafts, trail ruins, and trial chambers. The SeedFinder console runs scans in a browser using WebAssembly, without an account, key, or download. Its REST API accepts GET or POST requests and returns JSON, with examples for Python, Lua, and Node.js. The hosted API allows 60 requests per IP per minute, caps scan radius at 1,000 chunks, and returns no more than 200 results. An integration can display nearby structures in an in-game overlay through Flarial Client. SeedCracker requires coordinates for at least four structures. It also runs in the browser, but its hosted HTTP API is offline; the documented HTTP API runs on a local server. The site says browser scans run locally without connecting to the Minecraft world or a third-party seed map. The listed Free plan costs nothing.
