About Polyfork

Polyfork sells web-ready 3D assets that are generated by code instead of frozen meshes. Each remixable asset carries typed knobs for colors, proportions and part counts, and the model rebuilds as you turn them in the store or in the downloaded files. The catalog lists about 2,000 low-poly assets and themed kits, where every part in a kit shares one palette and scale so pieces fit together, and characters are described as configurations that can be changed.

In three.js an asset is added with a single import and no loader. Other engines read the format they already support: GLB for Godot, Blender and glTF-based engines, FBX for Unity, Unreal, Maya and 3ds Max, and USDZ for AR on iOS. Commercial use is allowed without attribution, and some assets are free.

The catalog is also exposed to AI agents through an MCP server and a self-describing REST API, so tools such as Claude Code, Cursor or Codex can search, preview and place assets. Browsing needs no key, and a pricing page lists the plans.
