Spline

Spline is a web-based 3D design platform with a free tier and paid plans starting at $12/seat/month. It enables designers to create and collaborate on interactive, production-ready 3D scenes directly in the browser using familiar design tools and AI-powered generation. Core capabilities include real-time rendering, a layer-based material system, and an event-driven interactivity engine for motion, physics, and data binding. Exports support web, mobile apps (Apple/Android), and code. The free plan includes limited files and watermarked exports. Starter at $12/seat/month (billed annually) adds unlimited files, uploads, and no watermark. Professional at $20/seat/month adds folders, video export, code exports, and AI credits. Enterprise offers custom pricing with SSO and priority support. Spline suits designers and developers building interactive websites, 3D mockups, gamified experiences, and animated characters without leaving the browser.
