Blockhammer vs Roxel

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.

Roxel is a free, open-source desktop voxel editor for hobbyists and indie creators, available for Windows and macOS. Its tools include brush, erase, recolor, eyedrop, select, move, and shape drawing. Rectangles, ellipses, and lines can be drawn on a build plane or extruded into 3D forms. An open-world grid allows painting across X/Z and upward as far as memory permits. Roxel includes built-in palettes, user palette management, and Adobe Swatch Exchange import and export. It opens MagicaVoxel .vox, Qubicle .qb, and Goxel .gox files, and exports .vox, .gox, .obj, .fbx, .glb, .png, and .svg. Projects use the .rox format; the maker says .glb exports are ready for Unity and Godot. Light, Dark, and System themes include customizable canvas and floor colors. The MIT license permits use, forks, and building on the project. Its itch.io page marks it in development and lists version 0.7.1 downloads. The maker says macOS builds are self-signed and not notarized, and Windows builds are unsigned.
