What is Spline?
Spline is a web-based 3D design platform that supports real‑time collaboration and instant rendering. Users can build interactive 3D experiences, websites, apps, and marketing assets directly in the browser with familiar tools such as primitives, modeling brushes, and a layer‑based material editor.
The platform offers an event system for adding animation, physics, particles, and interactive states, and it supports exporting designs to web, iOS, Android, and other frameworks through built‑in connectors to Webflow, Framer, Wix, and more. Spline integrates external data via variables, webhooks, APIs, and AI, enabling dynamic content updates in real time.
Designers and developers can remix community‑shared scenes, access a library of assets, and collaborate with comments or shared links, streamlining the workflow from concept to deployment. The tool is designed for teams in design, product, marketing, and engineering, allowing rapid prototyping of production‑ready 2D and 3D assets without requiring specialized coding expertise.
