MC Seed View vs SeedFinder

MC Seed View is a free browser-based Minecraft seed map viewer for examining a world before loading it. Its interactive maps cover the Overworld, Nether, and End, with zoom from a world view to chunk-level detail. The tool can locate more than 20 structure types, show coordinates, and provide teleport commands. Seed search finds worlds matching criteria and grades them from S to F using nearby structures, biome variety, and spawn quality. Loading a level.dat file can identify its seed, Minecraft version, and spawn point. Biome and structure calculations run in the browser using cubiomes compiled to WebAssembly; seed values are not sent to the operator's servers. The site says it can work offline after the first page load and can be installed as a Progressive Web App. It supports Java and Bedrock editions, though Bedrock biome accuracy is still improving. The map does not predict variable details such as trees, ore veins, and tall grass.

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.
