Open, view and edit Minecraft builds right in your browser — no download and no account. Drop in a .nbt, .schem, .litematic or .mcstructure file and it opens in 3D, with the full block list so you know what to gather.
Orbit the build, slice it layer by layer on the X, Y or Z axis, and play the build-it animation to see how it goes together.
Place and remove blocks, then export the edited build back out as a schematic file you can load into your world.
Every build comes with the exact block list and counts, so you know what to gather before you start.
