Why SeedMapView
Most seed maps show coloured biome patches and structure pins on a flat map. SeedMapView rebuilds the world itself: the same world generation code the game runs, compiled for your browser, with the exact terrain heights for Java 1.18 and newer and the game's own block textures.
| Feature | SeedMapView | Typical seed maps |
|---|---|---|
| 3D terrain built from real blocks and textures | yes | flat colours or none |
| Exact terrain heights (Java 1.18+) | yes | estimated or none |
| Ore veins with Y level | yes, 10 ores | rare |
| Teleport command onto the ground | yes | keeps your height |
| Read seed and version from level.dat | Java and Bedrock | rare |
| Find the nearest areas of any biome | yes | some |
| Chest loot for your seed | yes | rare |
| End Cities with ships (elytra) marked | yes | rare |
| Seed rating and visited tracking | yes | rare |
| Bedrock with full terrain detail | yes | structures only |
| A shareable page for every seed | yes | link parameters |
| Price, account, ads | free, none, none | varies |
How the map works
Minecraft builds a world from its seed with fixed rules: climate noise decides the biomes, terrain noise decides the height of every block column, and a seeded random grid decides where each structure may appear. SeedMapView runs those same rules. The map engine is cubiomes, an open-source copy of Minecraft's world generation, in its Java and Bedrock versions, compiled to WebAssembly so it runs at close to native speed in your browser.
For Java 1.18 and newer the engine also evaluates the game's terrain noise router, the function that decides whether each block is solid. That gives the true surface height of every column, which the map uses for the 3D world, the 2D relief, water and coastlines, the safe teleport height and the 1.18 terrain checks of structures. Bedrock 1.18+ generates the same terrain and biomes for the same seed, so Bedrock maps get the same detail.
The work is spread over several background workers: tiles for the 2D map, chunks of real blocks near the camera in 3D and larger columns further out, loaded nearest first while you move. Nothing about your world is uploaded; only the summary of a seed page (spawn, nearby structures, biomes) is stored so the page can show it to the next visitor.
How accurate is it?
Structure positions, biomes and the spawn come from the same rules as the game, and each supported version is checked against the official Minecraft server. The engine also runs the game's extra checks: End Cities need high enough End terrain, and in 1.18+ desert pyramids, jungle temples and woodland mansions are skipped where the ground is too low. Because the game decides those last three from the exact ground at the moment it generates them, they carry an "≈" note: now and then one does not appear.
What the map does not predict: trees are placed by biome rather than at their exact positions, caves and aquifers can cut through an ore vein, and anything players build or break. Read the details on the accuracy page.
Quick start
- Enter your seed. Type the number or text seed, or press the die for a random world. Text seeds are converted exactly like the game does.
- Pick edition and version. Choose Java or Bedrock and the version your world was created in; world generation changes between updates.
- Choose what to show. Tick structures, or open the Ores Finder for ore veins. Use Find a biome to jump to a biome.
- Explore. Drag to move, scroll or pinch to zoom, right-drag to rotate in 3D. Switch to 2D for slime chunks and the chunk grid.
- Go there in the game. Click a structure for its coordinates, nether coordinates and a /tp command, or mark it visited when you are done.

Frequently asked questions
What is a Minecraft seed map?
A seed map shows the world a Minecraft seed will generate before you load it: biomes, terrain, villages, strongholds and every other structure. SeedMapView runs the game's own world generation in your browser and draws it in 3D blocks or as a 2D map, with exact coordinates.
How do I find my world seed?
In Java Edition type /seed in chat (on a server you need operator rights). In Bedrock the seed is on the world settings screen. You can also press Open level.dat next to the map and pick your world's level.dat file: the seed, version and spawn are read automatically.
Which Minecraft versions are supported?
Java Edition 26.3 and every version back to 1.12, and Bedrock Edition 26.50 back to 1.18. Each update whose world generation changed has its own entry, so pick the version your world was created in.
Are the structure locations exact?
Positions come from the same placement rules the game uses, including the terrain checks for End Cities. For desert pyramids, jungle temples and woodland mansions the game also checks the ground at the last moment, so the map marks them as approximate.
Is the 3D terrain the real terrain?
Yes for Java 1.18 and newer: heights come from the game's own terrain noise, block by block, and Bedrock 1.18+ uses the same terrain for the same seed. Close up you see real block textures, cliffs, water and trees; trees are placed by biome, not in their exact game positions.
Does it work for Bedrock Edition?
Yes. Pick Bedrock above the map. Terrain and biomes match Java for the same seed since 1.18, and villages, strongholds and other structures use Bedrock's own placement.
Can I find diamonds and ancient debris?
Yes. Turn on an ore in the Ores Finder and zoom in: every vein is marked with its ore block and Y level, and clicking a vein gives its X, Y and Z. It works for Java 1.16 and newer.
How do I find a biome like a cherry grove?
Use Find a biome in the map panel: pick the biome and the map lists its nearest areas around the centre of the view. Click one to fly there. There is also a finder page for each of the 66 biomes.
How do I teleport to a structure?
Click the structure and press Copy /tp. The command puts you on the ground at that spot, never inside rock. Your world needs commands allowed (Esc, World Options, Allow Commands), otherwise use Copy X Z and walk there.
What does the seed rating mean?
Every seed page grades the world from S to F: how close a village and a stronghold are to spawn, how many other structures are within 1,000 blocks, how many biomes are around and whether rare biomes are nearby.
Can I see what is in the chests?
Yes, for Java. Click a desert or jungle temple, pillager outpost, shipwreck, buried treasure, ruined portal, fortress or End City and press Show loot: the map generates the chest contents for your seed and version.
Which End Cities have an elytra?
Only End Cities with an End ship have an elytra. On the map those cities carry a small elytra next to their icon, and the loot view says so too.
Can I keep track of what I have explored?
Yes. Click a structure and press Mark visited. Visited structures fade on the map and stay saved in your browser for that seed and version.
Why is my world slightly different from the map?
The map is your world as generated. Things the player changes, trees that grow from saplings and caves that carve through ore veins can differ. If structures are in different places, check that the version matches the one your world was created in.
Does it work on phones?
Yes. Drag to move, pinch to zoom and tap a structure for its details. The 3D view uses WebGL, which every current phone browser supports.
Is it free?
Yes. Every feature is free, with no account and no ads.
