A modern Sketchfab alternative
Voxobox is a browser-based 3D viewer and editor for glTF / GLB models.
Dial in materials and lighting once, save them as presets, and reuse them on every model —
then share a link, embed it, or drive it from code. No plugins, no installs.
Why people switch
Savable presets
Tune a PBR material or a lighting rig once, save it as a preset, and apply it to any model in one click.
No-upload local viewer
Drag a .glb straight into your browser to inspect it. The file never leaves your device.
Share & embed
Every model gets a short share link and an embeddable viewer for your own site.
Public API
A promise-first JavaScript API and REST endpoints, with an OpenAPI spec — built for developers and AI agents.
WebGPU rendering
Next-generation rendering with an automatic WebGL2 fallback. Zero configuration.
Edge-cached loads
Models stream from a global CDN and are cached for instant repeat views.
