Spline is a browser-based 3D design tool that makes creating interactive 3D graphics for the web accessible to designers who don't have 3D modeling backgrounds. It combines traditional 3D design capabilities with AI generation and a real-time collaborative interface. Spline AI allows generating 3D objects directly from text prompts within the design environment. Type a description and receive a 3D model you can immediately position, texture, animate, and refine within the same tool — eliminating the friction of switching between a generation platform and a design application. The Spline editor supports parametric 3D modeling, physics simulations, path animations, and state-based interactions. Designers can create scrollable 3D hero sections, interactive product showcases, animated backgrounds, and engaging visual effects that respond to user input. Spline's export capabilities are its killer feature for web designers: 3D scenes export as embeddable web components, React components, Spline iframes, or optimized code snippets that run directly in the browser with full interactivity. No WebGL expertise required. The collaboration features enable design teams to work on 3D scenes simultaneously with real-time cursor presence — similar to Figma for 3D. The community shares free templates and assets. Spline has become the go-to tool for product designers, UI/UX designers, and web developers who want to add premium 3D elements to websites and apps without a 3D background.
