Craftdex vs EZ Seed Finder

Craftdex is a free web directory and reference for Minecraft players, servers, skins, capes, and game information. Its Java seed map runs in the browser, calculating biomes, slime chunks, and structure positions from numeric or text seeds. Processing happens locally, so the seed is not sent to a server; markers stay in the browser for that seed and are not uploaded. Additional tools include Minecraft calculators, generators, finders, lookups, command builders, and server ping utilities. Reference material covers crafting, brewing, enchantments, effects, mobs, villager trades, food, fuel, blocks, biomes, structures, advancements, updates, and redstone. Craftdex says game data comes from Mojang asset data and is checked against Minecraft Wiki. Live player, server, skin, and cape listings use public Minecraft APIs and refresh continuously. The site describes itself as an independent, player-run fan reference, unaffiliated with Mojang or Microsoft. Its free plan costs nothing and supports both editions.

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.
