Polyfork

Polyfork is a low-poly 3D asset library built for the web. Every asset ships two ways: as a self-contained ES module (a factory returning a THREE.Group, one import, no loader and no async) and as a GLB for everything else, with turntable previews for both.

What separates it from a normal asset store is that the models are programs, not frozen meshes. Remixable assets carry typed knobs (curated palettes, per-part colours, proportions, part counts) that you turn in the store viewer and watch rebuild as you drag, then download in your own colours. Those knobs are also published as machine-readable JSON per asset, and the catalogue is exposed as an MCP server, so the asset tools appear directly inside Claude Code, Cursor or Codex with no install and no key to browse.

Parts that should move are separate named groups with pivots at the hinge or axle, so a lid, wheel or door animates with a one-line rotation. Themed kits bundle assets that share a single palette and one scale, so nothing clashes when you build a scene out of them.

The catalogue grows every week by 100+ assets, and one license gives access to all of them. The licence covers commercial use with no attribution: games, apps, client work, courses, commercial products. The only restriction is reselling the assets themselves.

Targets current three.js (r150+) using stable core APIs, and via GLB works with WebXR, Unity, Unreal, Godot, Blender and any other glTF engine.
