# 3dassets.dev

> A free, open marketplace of web-optimised GLB models for three.js, Blender, Godot, Unity and any glTF-capable tool. Every asset is validated, re-encoded (quantized geometry, WebP textures) and human-reviewed. New uploads use CC0 1.0 Universal: free for personal and commercial use without attribution. Contributors must accept the CC0 dedication.

Browse by category (what it is), theme (what world: sci-fi, fantasy, modern…) and style (what look: low-poly, realistic, voxel…). Assets load with a plain three.js GLTFLoader; no Draco or KTX2 loaders are required. Direct CDN URLs are CORS-enabled and immutable.
