EZ Seed Finder vs SeedFinder

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.

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.
