Sketchfab
Sketchfab is the largest dedicated platform for publishing, sharing, discovering, buying, and embedding interactive 3D content on the web. Founded in Paris in 2012 by Cedric Pinson and Alban Denoyel and acquired by Epic Games on July 21, 2021, Sketchfab hosts millions of 3D models from artists, museums, scanning rigs, and studios — much of it Creative Commons licensed. The platform exposes a public REST Data API for programmatic upload and content management, a JavaScript Viewer API for controlling the embedded WebGL/WebXR viewer, a Download API delivering glTF/GLB/USDZ, an oEmbed endpoint, and OAuth 2.0 authentication, alongside native exporters for every major 3D / DCC tool. Following the Fab.com launch in 2024 the Sketchfab Store has been retired into Epic's unified content marketplace while the publishing, viewing, and developer APIs remain on sketchfab.com.
