Interactive Minecraft Seed Map & Biome Finder
Generate accurate seed maps for Minecraft Java and Bedrock Edition. Explore biomes, navigate exact X/Z coordinates, inspect underground cave Y-levels, and preview world generation directly in your browser.
Calculations run locally on your device for fast performance and complete privacy. Both 64-bit numeric seeds and text seeds are fully supported using Java-compatible hashing for both editions.
Locate Minecraft Biomes and Structures
Biome Search & Highlight
Search every registered biome across dimensions. Highlight specific biomes like Cherry Groves or Deep Dark while dimming non-matching areas on the map.
Structure Finder
Pinpoint exact coordinates for Trial Chambers, Ancient Cities, Strongholds, Villages, Nether Fortresses, and Outposts in visible map areas.
Surface, Height & Region Map Layers
Toggle between terrain surface projections and fixed Y-level slices. Uses hillshading, sea-level overlays, and a 32 × 32 chunk region grid to make world exploration intuitive.
Right-click any coordinate to copy a ready-to-use /teleport command in Java or Bedrock syntax. Share maps instantly preserving your seed, dimension, coordinates, and active filters in a single URL.
Worldgen Datapack & Mod Support
Load Java worldgen datapacks (ZIPs) or mod JARs to visualize custom biomes and structures alongside vanilla content seamlessly.
Search and load compatible worldgen projects directly via built-in Modrinth integration. Files are parsed locally on your machine and never uploaded to any server.
Minecraft Seed Map & Finder FAQ
How does the Minecraft Biome and Structure Finder work?
Choose Java or Bedrock Edition, enter a seed and select a dimension. The finder runs Minecraft world-generation calculations in your browser to draw the biome map and evaluate possible structure positions.
Does the finder upload my seed or datapacks?
No. Seeds, ZIP files and compatible JAR files are processed locally in your browser. Recently opened local packs can be stored by your browser on this device.
Can I use text as a Minecraft seed?
Yes. Modern Java and Bedrock use the same Java-compatible text hashing behavior. Signed 64-bit numeric seeds are preserved exactly.
Can this map show the Nether and the End?
Yes. Switch between the Overworld, Nether and End. The available biomes, map height, terrain projection and structures update for the selected dimension.
Does it support Minecraft datapacks and mods?
Java Edition supports worldgen datapacks and compatible mod JARs that use data-driven world-generation files. Bedrock Edition currently maps vanilla generation; behavior-pack worldgen is not loaded.
Are structure positions always exact?
Java structures use their data-driven placement and generation checks. Bedrock structures use Bedrock-specific Mersenne Twister placement and biome checks; because Mojang does not publish every final Bedrock validation rule, rare false positives or omissions remain possible.
