Voxelier

What Voxelier is

Voxelier is a native Minecraft terrain editor for creating and changing playable worlds. It combines stackable terrain layers with sculpting, painting, and custom brush masks, and offers both top-down 2D and navigable 3D editing, including a first-person camera. A visual node editor can generate terrain by linking noise, masks, operators, and material outputs without code; scripts can also read and change terrain and materials through its embedded Rhai engine and map API. Voxelier works with Axiom, Litematica, and WorldEdit schematic formats and can convert between them. It imports OBJ and GLB models and turns them into blocks at a chosen resolution. Other tools cover grayscale heightmaps, colormap images, water and lava, flood fill, sponge removal, ocean levels, and river carving. Projects export to playable Minecraft worlds, with heightmap and colormap export also listed. Voxelier has a free plan with no account required and is listed for Windows and the web; the web demo requires a browser with WebGPU, such as recent Chrome or Edge.
