ChunkSeeds Seed Finder vs Ezseed Minecraft Seed Finder

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.

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 Results may be incomplete, approximate, outdated, or wrong for some versions, coordinates, devices, or edge cases.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.
