p3d.in vs Sketchfab

p3d.in is an online 3D model-sharing platform and community for animation and visualization projects. Models open in modern browsers without plugins and can be shared by link or embedded on websites with configurable viewer settings. Upload support includes OBJ with MTL files and textures, while the listed formats also include glTF, GLB, FBX, and STL. Hotspots can mark details, move the camera, show descriptions, control animations, and contain nested hotspots. Variants can hide or show model parts for different configurations, including product configurators described as requiring no coding. Compatible models can be viewed in augmented reality through a suitable Android or iOS camera without another app. Models may be public, unlisted, or private; unlisted links can be viewed by anyone with the URL, while private models are owner-only. Plus and higher accounts can use the JavaScript Embed API to control animations, textures, variants, camera movement, and hotspots in web apps. Basic is free with 100MB storage and model size. Plus costs $6 a month, and Premium costs $50 a month.

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.
