Spline review

Spline is a browser-based 3D editor aimed at interactive scenes rather than objects you print. You model and style 3D elements, add interactions and publish them to the web, and paid plans extend export to Apple and Android apps. A 2D editor sits in the same workspace, and the free plan includes the Spline Library, templates and unlimited viewers. The free plan is tight, though: Spline lists limited personal files, no AI credits and web exports carrying a Spline logo. Hobby costs $12 per seat a month billed annually, or $15 monthly, and adds unlimited files, watermark-free web exports, material and audio libraries and 2,000 AI credits a month. For makers, the important detail is that STL export for 3D printing and USDZ for iOS AR sit on the Pro plan at $25 per seat a month billed annually. Students building portfolio sites will get the most out of the free tier.
