Paint
every
block.

Blockwire is an open-source voxel world where nothing is pre-made. Paint a block face by face, or sculpt it voxel by voxel. Save it as a recipe only you can open. Then produce copies and sell them to other players.

Click and drag to paint. This is the real thing.
Two editors

Flat or solid. Your call.

Every block starts empty. Paint its six faces like pixel art, or go inside and carve it out of voxels. Both save to the same kind of recipe.

The painter

A 16×16 grid per face, six faces per tile. Straightforward pixel art with the tools you'd expect.

  • Paint, fill, eyedropper, brush sizes
  • Per-pixel opacity — erase for windows, dial it down for tinted glass
  • Blocks up to 4×4 tiles, placed as a whole wall
  • Doors that open, painted front and back

The voxel editor

Each cell is 16×16×16 voxels. Rotate the block and sculpt it directly in 3D.

  • Add, delete, or paint one voxel — or just one side of it
  • Start from a solid cube and carve, or from nothing and build
  • Rectangle fill for big shapes
  • Up to 4×4×4 cells of room to work in
Recipes and products

What you make stays yours.

Selling a block shouldn't mean giving away how you made it. Blockwire splits the source from the copy, so you can trade freely without handing over your work.

The recipe is private

Your paint and voxel data, editable, owner-only. It never leaves your hands — nobody else can open it.

The product is public

A frozen copy with no source attached. Place it, stack it, sell it. It can't be opened or reverse-engineered.

The market is the point

Sell products for coins and build a reputation on your designs — not on who copied them fastest.

Open source

Take it apart.

Blockwire is open source and moddable by design. Read it, fork it, break it, or build something else out of it.
