What is Spline?
Spline is a web-based design tool for creating 3D scenes and interactive 2D interfaces directly in the browser, with real-time collaboration so several people can work in the same file. It includes primitives, 3D modeling, layer-based materials, timeline animation, physics and particles, and an event system for states and interactions. Its AI agent helps with editing and generation, including AI 3D generation and texture generation.
Once a scene is finished, it can be exported to the web as an embeddable viewer (via a script tag or framework components for Webflow, Framer, React, Next.js and others), or to iOS and Android. Teams can connect live data through variables, webhooks and APIs. Typical uses include interactive websites, product mockups, 3D logos, animated characters and brand visuals.
