Chunkbase Seed Finder vs Ezseed Minecraft Seed Finder

Chunkbase Seed Finder searches for Minecraft seeds that meet conditions you set. Choose Java or Bedrock and the game version, then search for biomes, islands, terrain height, nearby features, or feature clusters in the Overworld and Nether. You can measure conditions from world spawn, the origin, or custom coordinates. Nearby searches cover up to 2048 blocks in a square or circular area. Presets include island starts with a nearby village, several villages near spawn, speedrun-friendly starts, and a large mushroom island at the origin. Results appear in a list with a map preview; you can copy or favorite seeds, or open one in Seed Map. The app saves your conditions and latest search, including results, locally and restores them when you return. It works on phones and tablets, though a fast multi-core CPU can check more seeds in the same time. Searches stop at a result or time limit; Search more continues them. Spawn locations are estimates, and feature locations or sampled terrain conditions may be inaccurate or incomplete.

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 Results may be incomplete, approximate, outdated, or wrong for some versions, coordinates, devices, or edge cases.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