About Spline

Spline democratizes 3D design by providing an approachable interface that feels familiar to UI/UX designers comfortable with tools like Figma. Users can create parametric 3D objects, add physics, and build interactive states driven by scroll or cursor events. The real-time collaboration features allow teams to work together on 3D scenes simultaneously in the browser. Spline's export options include React components, iframe embeds, and video exports, making integration into web projects straightforward. The growing template library and AI generation features further lower the barrier to creating polished 3D content for the web.
