Blockhammer vs VoxelDraft

Blockhammer is a free voxel editor for building scenes from cubic blocks, available for macOS, Windows, and Linux. Its modeling tools include layers, named objects, precise position and size controls, reversible effects, and undo. Painting works on block faces at sixteen times the blocks’ resolution and supports text, images, glass, metal, and glowing paint. Blockhammer imports and exports MagicaVoxel .vox files, and exports .glb, .obj, Minecraft .schem, and image or animation formats. Export destinations named by the maker include Unity, Unreal, Godot, Blender, Minecraft, and Teardown. The maker reports rendering a 113-million-block scene and testing scenes beyond one billion blocks. The editor autosaves every minute and can recover work after a crash. Scenes and files remain on the user's machine, and no account is required. Crash reports may include errors, recent activity, and graphics hardware details; reporting can be disabled. Optional AI texture generation is off by default and uses the image API configured with the user's own key. The software is in active development, so features may change.

VoxelDraft is a browser-based voxel editor for creating 3D voxel art, block models, and game assets. Its workspace lets you place, erase, paint, mirror, select, and organize blocks while rotating a 3D view. A PNG or JPG can be converted into editable voxel art through flat, height-map, or extrusion modes. The maker lists image, GIF, OBJ/MTL, GLB, VOX, and schematic exports, with workflow guides for Unity, Blender, Godot, Minecraft, and Roblox Studio. You can share editable model links, embed an interactive 3D viewer, and open Gallery works as editable copies. The editor runs in modern desktop and mobile browsers without payment or an account. Projects are local by default; cloud saving is optional. The Free plan is free, with no subscription, and includes the editor, manual private cloud save, and cross-device cloud project access.
