Craftdex vs SeedFinder

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.

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.
