Polyfork

Polyfork is an AI-native 3D asset library providing low-poly models and code programs for web and game engines.

Polyfork provides over 3,000 low-poly 3D assets and themed kits that function as small programs with typed knobs for recoloring and reshaping. Assets can be remixed directly in the browser or store, and exported as GLB, FBX, USDZ, or ES modules for use in three.js, Unity, Unreal, Godot, and Blender. It is designed for developers, designers, and AI agents, featuring an MCP server endpoint for tools like Claude Code, Cursor, and Codex. Every low-poly asset is free for commercial use, while a Pro subscription unlocks high-poly HD editions with PBR materials and a dedicated CDN.
