World seed
Numeric or text — text seeds hash exactly the way the game does
Drag to pan · scroll to zoom · click the map to drop a marker · click an icon for its coords. Buried treasure, mineshafts, geodes, desert wells and end gateways are per-chunk features — they only appear once you zoom in far enough to draw them sanely.
Find nearest
Spirals out from a point until it lands a biome-valid structure — or the closest patch of a biome
Pick a structure or a biome and hit Find nearest — the result lands here.
The search spirals out from your origin and biome-validates every candidate, so what you get back is where the structure — or that patch of biome — really generates.

Name it and pick a colour — it's saved against this seed and comes back next time you open it.
How the seed map works
Real worldgen math, run locally
Minecraft worlds are deterministic — every biome, structure and slime chunk is decided by your seed before you ever load the world. Plug in a seed and Crafty runs the same noise + structure math the game does, then paints the result onto the map.
The biome layer is rendered using a WebAssembly port of cubiomes, the most accurate open-source reimplementation of Mojang's world generator. Structure positions come from the same library, then re-validated against the biome to filter false positives.
Everything runs locally in your browser. Your seed is never sent to a server. Tile bitmaps are cached in IndexedDB so the second time you open the same view, it's instant — and the map keeps every zoom level it has already drawn, so zooming stretches what's on screen instead of blanking while the next level generates.
Tips & shortcuts
Everything the map does that isn't obvious
- Left-click the map to drop a named, coloured marker — it's saved per seed in this browser.
- Click a structure icon for its exact coords, a ready-made
/tpcommand, and a visited tick. - Double-click to zoom in on a point; scroll or pinch for smooth continuous zoom.
- Keyboard: R random seed, F full screen, G go to spawn, arrows pan, +/− zoom.
- Click the coordinate box on the map to copy the biome name under your cursor.
- Strongholds are computed via the iterative biome-validated algorithm — exactly the in-game positions.
- The URL captures the seed, viewport, layers and biome highlight — share or bookmark it.

FAQ
Seed map questions, answered
How do I find my Minecraft seed? +
In Singleplayer, open the world and run the /seed command in chat — it prints the integer seed used to generate the world. On a server, the operator can run /seed if cheats or the server console allow it. You can also see the seed inside the level.dat file or on the world-creation screen before launch. Paste that number (or any text — text seeds are hashed deterministically) into the seed field above to render the same world map.
Can I save my own markers on the seed map? +
Yes. Left-click anywhere on the map to drop a marker, give it a name and pick an icon colour, and it is saved in your browser against that seed — reopen the same seed later and your markers are still there. Markers are listed under the map with their coordinates, and you can tick generated structures off as visited. Everything is stored locally with localStorage, never uploaded, and the Export button writes a JSON backup you can import on another device.
What Minecraft versions does the seed map support? +
This seed map supports Minecraft Java Edition versions Java 1.18.2, 1.19.4, 1.20.6, 1.21.1, 1.21.3. Worldgen rules differ between versions, so loading the same seed under different versions can show different terrain. Pick the version that matches the world you actually generated. Bedrock Edition uses a different worldgen and is not supported. Last verified for Minecraft data version 26.2.
Can I view Nether and End biomes on the seed map? +
Yes. Switch the dimension toggle from Overworld to Nether or End. Nether shows the five Nether biomes plus fortresses, bastions, and ruined nether portals. End shows end islands, end cities, and end gateways. Strongholds and ancient cities are Overworld-only since they don't generate in the other dimensions.
Is this Minecraft seed map accurate? +
Yes — biomes and structure positions come from cubiomes, the same open-source library used by professional speedrun and seed-finding tooling. Each candidate structure is biome-validated against the in-game placement rules to drop false positives. Strongholds use the iterative biome-validated algorithm and resolve to exact in-game coordinates, and the world spawn shown on the map is the real spawn search result rather than 0, 0.
