Ezseed Minecraft Seed Finder vs SeedFinder

Ezseed Minecraft Seed Finder is a free browser tool for locating Minecraft worlds that match chosen structures and biomes. Structure filters can target mapped structures, require a count from 1 to 10, and set a radius and center point. Biome filters look for any biome within a specified radius, and multiple conditions can be combined so every one must match. The finder supports Java 1.20 through 26.2 and Bedrock up to 26.30. Each matching result opens on a full seed map for inspection before play, and the map state in the URL can be bookmarked or shared. Searches run in the browser using the selected edition's world-generation rules. Seed calculations run locally through cubiomes WebAssembly; Ezseed says seeds are never uploaded and the tool works offline once loaded. The listed free plan requires no download or account. Results may be incomplete, approximate, outdated, or wrong for some versions, coordinates, devices, or edge cases. Ezseed describes the utility as fan-made and says it is not approved by or associated 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.
