A free browser studio for voxel game assets. Model, rig and animate characters, then export GLB or MP4. Built with GPT-6 Astra, with WebMCP tools for agent-assisted creation. A web port by Hammy of VoxEdit by The Sandbox.
Astra made it practical for us to build an entire browser-based modeling, rigging and animation studio. We then exposed its editing tools through WebMCP, so Astra can create and refine game assets inside the tool it helped build. That enables a workflow from a natural-language brief to editable geometry and animation, with creators able to inspect, adjust and export the result.
Hey Product Hunt! I'm Hammy, the maker of VoxEdit Web — a browser port of VoxEdit by The Sandbox.
VoxEdit Web is a free place to create voxel characters and props, assemble reusable parts, rig them, add animation and export the result for a game or a video.
For the GPT-6 Astra Challenge, I'm sharing a tool I vibe-coded with Astra. Astra can also use the finished editor through native WebMCP to build and refine game assets. The tool it helped create becomes part of the creative workflow.
You keep an editable result. Agent actions and manual edits share the same document and undo history, so you can repaint a part, adjust a joint or change a keyframe yourself.
A few things to try:
• Create a character from colored voxels and reusable parts.
• Pose and animate it with editable keyframes.
• Use Render view for a clean studio presentation.
• Try Build view, which drops the voxels into place, and export an MP4.
• Export a GLB or an editable project for the next step.
The browser tool is free. Agent-assisted creation requires a compatible agent and WebMCP-capable browser; that service may have its own pricing.
VoxEdit Web is a distinct web port. VoxEdit and The Sandbox belong to their respective owner.
What would you make first: a character, a prop or a tiny world? I'd love feedback on the modeling and animation workflow.
