How to use it
- Type /seed in game and copy the number into the seed box (text seeds work too).
- Pick the Java version your world was created in.
- Enter your current X and Z to sort the ancient cities by distance from you.
- Copy the /tp command, or open the spot on the seed map to see the biomes around it.
How it works
The finder recreates Minecraft's own structure placement from the seed in your browser, using the open-source cubiomes library compiled to WebAssembly. For each area where a ancient city can start, it works out the exact start point, then checks the biome there the same way the game does. Deep under the Deep Dark biome, with the floor at Y -51. They try to spawn once in every 24 × 24 chunk area, at least 8 chunks apart. Nothing is uploaded: the seed stays on your device.
Questions
How do I find a ancient city without the seed?
Explore the biomes where they spawn: deep under the deep dark biome, with the floor at y -51. On servers where you can't use /seed, ask an admin, or look for a seed shown on the server's website.
Does this work on Bedrock Edition?
Not for structures. Bedrock shares Java's biome generation since 1.18, but it places structures with different rules, so these coordinates only match Java worlds.
Is using a finder cheating?
It reads the same information the game uses to build your world. In single player it's up to you; on servers, check the rules, because some ban seed tools.
What will I find in a ancient city?
Swift Sneak enchanted books, enchanted golden apples, echo shards and the Disc 5 fragment. Watch out for sculk shriekers: they summon the Warden.
What Y level are ancient cities at?
The main floor is at Y -51 in every ancient city. Dig down to around Y -48 at the coordinates the finder gives, then look for deepslate tiles and sculk.
