Craftdex vs MC Seed View

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.

MC Seed View is a free browser-based Minecraft seed map viewer for examining a world before loading it. Its interactive maps cover the Overworld, Nether, and End, with zoom from a world view to chunk-level detail. The tool can locate more than 20 structure types, show coordinates, and provide teleport commands. Seed search finds worlds matching criteria and grades them from S to F using nearby structures, biome variety, and spawn quality. Loading a level.dat file can identify its seed, Minecraft version, and spawn point. Biome and structure calculations run in the browser using cubiomes compiled to WebAssembly; seed values are not sent to the operator's servers. The site says it can work offline after the first page load and can be installed as a Progressive Web App. It supports Java and Bedrock editions, though Bedrock biome accuracy is still improving. The map does not predict variable details such as trees, ore veins, and tall grass.
