Jatayu 3D vs Sketchfab

Jatayu 3D is a browser-based 3D assembly viewer for engineers, managers, and suppliers. It runs on the web and Windows, with mobile also listed as supported. Formats include STEP, IGES, JT, STL, ESF, ECAD 3D STEP export, GLB, and OBJ. Viewer tools provide slicing, exploded views, part isolation, wireframe, transparency, and measurements for distance, angle, and wall thickness. Users can pin 3D annotations, comment, share session links, and export marked-up PDF review reports. Athivex says its WebGL renderer handles 100,000 or more parts at 60 FPS on a standard office laptop with Intel UHD graphics or better. The product includes an in-house native JT reader. The page describes session-verified DRM tokens and says geometry is not written to local disk or browser cache. The free Student plan allows files up to 50 MB and assemblies up to 10,000 parts. Professional is billed per seat; Ultra uses custom billing and lists unlimited file size and parts scale.

Sketchfab is a platform for publishing and finding 3D content through an interactive viewer. The viewer can be embedded on websites, allowing 3D and VR viewing without leaving the host site. Its built-in editor adjusts orientation, materials, lighting, camera parameters, and post-processing filters. Upload formats include OBJ, FBX, Blender, STL, and glTF, and exporter plugins are available for Blender, Maya, SketchUp, Unity, and ZBrush. APIs support model uploads, data access, downloads, and viewer control or embedding. The Download API provides glTF, GLB, and USDZ, not source formats such as FBX and OBJ; owners control whether their models are downloadable. Basic is free and allows model files up to 50MB. Pro costs $15 a month billed yearly, with a 200MB model limit and private uploads. Premium costs $79 a month billed yearly, with a 500MB limit and advanced embed customization. Enterprise pricing is by quote.
