Chunkbase Seed Finder vs EZ 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.

EZ Seed Finder searches for Minecraft Java Edition seeds through a graphical interface or the ezsf command-line tool. Its .ezsf criteria language supports random or sequential scans, seed ranges, thread counts and result limits. A search can combine checks across the Overworld, Nether and End, including structures, biomes, spawn conditions, strongholds, bastion variants, distances between structures, mobs and chest loot. Structure options include villages, temples, mansions, monuments, ruined portals, ancient cities and trial chambers. Results appear in a table, and double-clicking one copies its seed. The search engine uses cubiomes through a vendored cubiomespi-fork build. The package runs on Linux, macOS and Windows and requires Python 3.11 or later; the GUI also requires tkinter. Windows installation may require Microsoft C++ Build Tools to compile the native library. Stronghold and terrain results have accuracy limits: full-stronghold checks use a ring-1 proximity heuristic, while terrain and height checks are experimental biome-based proxies rather than true surface-noise analysis. The project is MIT-licensed and free, with no map preview.
