Are these 3D assets really free?

Yes, and permanently. Every model is released under CC0 1.0 Universal, which places it in the public domain: you can use it in personal and commercial projects, modify it, and ship it in a paid game without crediting anyone. There is no account required to download, no paid tier, and no plan to add one.

What format are the models in?

Binary glTF (.glb) only, with textures embedded in the file. Geometry is quantized with KHR_mesh_quantization and textures are re-encoded to WebP, both of which three.js supports natively, so a model loads with a plain GLTFLoader. There is no Draco or KTX2 decoder to configure.

Can I hotlink the files instead of downloading them?

Yes. Every asset has a permanent CDN URL on cdn.3dassets.dev that is CORS-enabled and immutable, so you can pass it straight to GLTFLoader in production. Because the URL never changes content, you can cache it aggressively.

Do I need to credit 3dassets.dev?

No. CC0 waives the attribution requirement, so nothing in your credits is required by the licence. A link back is welcome but it is entirely your choice.

Can an AI agent search and download assets for me?

That is what the site is built for. There is a JSON REST API, a Markdown view of every asset, an llms.txt index, and an MCP server your assistant can connect to in one line. Each asset response includes ready-to-paste three.js and React Three Fiber snippets.

Can I upload my own models?

Yes, and you take on no obligation beyond releasing the work under CC0. Sign up with a username and an email, upload a .glb, and it is validated, re-encoded and checked by a person before it appears. Every submission is reviewed, including ours.

How big can an asset be?

Up to 5 MB and 1,000,000 triangles per file, with at most 32 textures at 4096 pixels square and 64 materials. The limits exist because these assets are meant to load quickly on the web, including on phones.

What is the difference between an asset and a pack?

An asset is a single model. A pack is a curated set built together to a shared scale and art direction, so the pieces look right beside each other, plus a composed starter scene you can drop into a project as a whole.

One prompt. A world of assets.

Paste the prompt into your assistant. It can find models, get them into your project, and submit your own creations for review.

Works with agents that can read links and call APIs. Uploading local files also needs file access. Finding assets needs no account.
