MC Toolkit / World
World
See what a world holds before you travel, and plan where to build, mine and settle.
Seed Map
Type a seed and see the world before you play it: biomes, villages, ocean monuments, slime chunks and more. Java and Bedrock, 1.20 through 26.3, in your browser.
3D Seed Viewer
Look at any Minecraft seed in 3D: real terrain height, trees and structure markers across the overworld, nether and end. Java and Bedrock, nothing to download.
Earth Map Generator
Pick any spot on Earth and turn it into a Minecraft Java world in your browser: real buildings, streets, terrain and water from OpenStreetMap, built by Arnis.
Ore Distribution
Best Y-levels for every ore, drawn from the game's real worldgen data — drag to your mining depth.
Minecraft World & Biomes Tools
Browse biomes, ore Y-levels, structures, dimensions, and flat world presets.
World Border & Difficulty Tools
Plan your world's playable area with ready /worldborder commands, and compare difficulty/gamemode settings.
Seed Finder
Find Java seeds with the biomes, villages and structures you want near spawn, or flat ground. It searches in your browser and every match opens on the seed map.

/locate, explorer maps, Eyes of Ender and dolphins all search a limited range. The real ranges from the 26.3 code, and why /locate misses buried treasure nearby.
How to play Minecraft for free: the legal ways, and the demo's rules
The official free trial, Minecraft Classic and the Realms trial — plus what the Java demo does, read from its code: 100 minutes, one fixed world and a reset button.
Biome temperature decides rain, snow or nothing — and 18 biomes get no weather at all
67 biomes in 26.3. Every biome at temperature 2.0 is dry, all six remaining dry ones are in the End, and only 10 biomes snow at every height.
Six version options, four world generators — three of them are the same world
26.1, 26.2 and 26.3 all resolve to one generator in the seed map — though 26.3 added a biome it cannot draw yet. And 1.21.1 and 1.21.3 are different generators, which catches people mid-line.
The seed map's four generators: terrain changed at 1.21.2 and 1.21.4, and the game kept going
The four generator ranges, spelled out. 1.21.4 through 26.2 share one generator in the seed map — but 26.2 added sulfur caves and 26.3 dappled forests and abandoned camps, so the newest worlds are not fully drawn.
/worldborder has ten forms, and only two of them animate
set and add take an optional time argument that shrinks the border gradually; the other eight are instant. Plus what Minecraft's four border defaults actually mean.
