Less a download library and more a hosting and viewing platform: Sketchfab embeds interactive 3D and AR content anywhere on the web, with its own PBR rendering toolset for lighting, materials and VR positioning.
The embeddable viewer is the real product; a model lives on Sketchfab and can be dropped into a store page, social post or portfolio without the visitor needing any software.
Fits e-commerce, advertising and portfolio use cases where the goal is showing a model interactively, not necessarily downloading raw geometry.
Sketchfab runs its own marketplace (Fab) for buying and selling models, on top of free viewing and paid Pro plans.
The leading platform for publishing and viewing 3D and AR content on the web.
