What is ChunkScan?
ChunkScan is a free Minecraft seed finder that lets you search through hundreds of thousands of pre-analyzed worlds to find the perfect seed for your next adventure. Whether you're looking for an island spawn, a village at your feet, or a rare cherry grove biome — ChunkScan has you covered.
Unlike random seed generators, every seed on ChunkScan has been fully scanned and analyzed. That means you can filter by exact structures, biomes, terrain features, and spawn conditions — and get accurate results instantly.

Find flat worlds for building, mountainous terrain for dramatic views, island archipelagos for survival challenges, or cliff coasts for scenic bases.
Spawn Conditions
Filter for island spawns (surrounded by water), cave spawns (underground), or village starts (village within 100 blocks of spawn).

Frequently Asked Questions
Do these seeds work in my Minecraft version?
Yes — select your version and edition (Java or Bedrock) in the search filters. World generation differs between versions, so ChunkScan scans each version separately to ensure accuracy.
How many seeds are in the database?
ChunkScan is continuously adding new seeds. The goal is 250,000+ seeds per version and platform combination, totaling over 2 million analyzed worlds.
Can I use these seeds on a server?
Absolutely. Copy the seed number and paste it into your server's server.properties file or the world creation screen.
Is ChunkScan affiliated with Mojang?
No. ChunkScan is an independent fan project. Minecraft is a trademark of Mojang Studios / Microsoft.
