Every model is a game-ready GLB with PBR materials, so it drops straight into Three.js, React Three Fiber, Babylon and model-viewer. Triangle count, file size and format sit on every card, because that is what you actually filter by. The free ones download straight from this page: no account, no email, commercial use included.
Upload one image, get the model back. The same pipeline that built this library is the product: your asset, your art direction, ready for the web.
