ChunkSeeds Seed Finder vs SeedFinder

ChunkSeeds Seed Finder is a free web tool for searching Minecraft seeds by combined world conditions, such as nearby structures, biomes, or terrain. Results must satisfy all selected conditions, and include matched structures with their distances; users can copy a seed or open it in an interactive map. The finder samples a random portion of seed space, so repeated searches can return different matches. A standard pass scans up to 350,000 seeds, while rare combinations may yield fewer results or take longer. Users choose a Minecraft version because structure and biome placement can change between versions. Reverse seed search currently supports Java Edition; the page directs Bedrock users to verified seed lists. The tool costs nothing, requires no account, and the maker says it runs on the user's own machine in a browser. The privacy policy says the site collects analytics and technical request details and may be supported by advertising. The maker does not guarantee game data is accurate, complete, or current, and describes the resource as unofficial and unaffiliated with Mojang Studios or Microsoft.

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.
