Let me set expectations honestly, because Shopify and Etsy are in different universes on 3D, and most articles pretend otherwise.
Shopify is the good news. It supports 3D models natively on product pages, and there is a real ecosystem of Shopify 3D model apps for viewers, AR, and configurators. You upload a GLB, optionally a USDZ for iPhone AR, and the product page gets a 3D viewer. It genuinely works. This is the closest thing the 3D space has to plug-and-play, and if you sell on Shopify, the app question is mostly which viewer, not whether 3D is possible. Nice problem to have.
Etsy is the complicated news. Etsy does not host 3D viewers on listings. That is not a rumor or a temporary gap. It is just how the platform works right now. So an Etsy Shopify 3D listing app strategy has to be a workaround strategy: host the viewer on your own site or a hosted viewer page, and link it from your listings, your shop banner, and your thank-you messages. Some sellers also use short 3D turntable videos as listing images, which Etsy does support. A rotating product video is not interactive 3D, but it answers the same shopper question, and it lives natively on the listing where buyers actually look. Practical beats perfect.
When you are evaluating options, check the right things per platform. For Shopify: does the app handle both GLB and USDZ, what does it do to your page speed, how does pricing scale with your catalog. For Etsy workarounds: does the viewer give you a clean shareable link, and how does it look on a phone, since that is where most Etsy traffic lives. For both: what happens to your models if you cancel. Portability matters more than people think until the day they need it.
The Photo3DTools database tracks which tools and apps support Shopify 3D, which export the formats each platform needs, and what each one costs, so you are checking real specs instead of guessing.
Or bypass the whole app question. I generate 3D models per product for Shopify and Etsy sellers, delivered in the formats your store needs, at photo3dtools.com.
