Sketchfab is a 3D modeling platform website to publish, share, discover, buy and sell 3D, VR and AR content. It provides a viewer based on the WebGL and WebXR technologies that allows users to display 3D models on the web, to be viewed on any mobile browser, desktop browser or Virtual Reality headset. The company behind it is today based in Paris and New York City. Sketchfab took part in the Spring 2013 TechStars New York City startup accelerator program, raised 7 million in June 2015. On July 21, 2021, Epic Games acquired Sketchfab. It was later announced that Sketchfab will be phased out and merged into Epic Games's new marketplace called Fab. The main product of Sketchfab is a 3D, Virtual reality (VR) and Augmented reality (AR) model viewer. It enables users to move freely around or inside the 3D scene using mouse, touch manipulation, VR or AR. In addition to static 3D models, the viewer is able to play and control 3D animations. Viewers can enable the VR mode to see the model in Virtual Reality headsets or the AR mode to insert the model within the real world via a mobile device. The 3D viewer is used on the Sketchfab website and mobile apps, but can also be embedded on external websites, notably on Facebook, Twitter or Wordpress. Sketchfab provides online and mobile community portals, where visitors can browse, rate, download or buy user generated 3D models. Users of Sketchfab have profile pages, premium users can customize and share their models privately. Sketchfab users can choose to make their 3D model files available for download under Creative Commons licenses or to sell them in the Sketchfab store. With content available for sale or download, Sketchfab is positioned as a 3D model marketplace and as a 3D printing marketplace since some models are compatible with 3D printing. Sketchfab offers to paying enterprise customers a dedicated platform to share, manage and collaborate on 3D assets. A selection of Sketchfab models are available within a native application for the following VR headsets: Google Cardboard, Samsung Gear VR, HTC Vive and Oculus Rift.
