Chunkbase Seed Finder vs KLIMATA

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.
