Roxel vs Voxel Builder

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.

Voxel Builder is a voxel-based 3D modeling application for creating and editing voxel scenes. It includes terrain, cube, sphere and isometric generators, alongside interactive modeling, symmetric drawing and painting, transforms and color groups. Rendering tools include a Three.js sandbox, GPU path tracer, basic PBR rendering and post-process effects. The app can voxelize GLB, OBJ, STL and PLY models, as well as images and Unicode or emoji text. It saves and loads JSON and MagicaVoxel VOX files, and exports GLB, GLTF, OBJ, STL and PLY. Local storage, snapshots, quicksave, undo and redo are available, with snapshot backups shareable in ZIP archives. A Blender importer script is included, and baked GLB meshes can be used with Blender and other 3D software. The project describes the app as portable and usable online or offline, with no ads, trackers or logging; its code is GPL-3.0. Browser use is supported on desktop and mobile, and Electron downloads are listed for Linux x64 and Windows x64.
