spline.design

Browser-based 3D design tool with real-time collaboration, animation, physics and an AI agent for building interactive web experiences.

What is Spline?

Spline is a web-based 3D design platform covering modeling, layered materials, timeline animation, states and events, game controls and physics. An AI agent works alongside the editor for agentic editing, and real-time data can flow in through variables, webhooks and APIs. Finished experiences ship to the web, iOS and Android, including a Webflow embed via the Spline viewer, and you can start by remixing community designs.
