Chunkbase Seed Finder vs Craftdex

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.

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.
