Spline is a design tool that brings 3D and interactivity to the web in a way that's approachable for ordinary designers rather than just specialists. Traditionally, creating 3D graphics required complex, intimidating software and deep technical knowledge, which kept three-dimensional visuals out of reach for most product and web designers. Spline changes that by offering a browser-based, collaborative environment where you can model, animate, and add interactivity to 3D scenes with a friendliness closer to a modern 2D design tool — opening up a whole dimension of creative expression to people who would never have touched traditional 3D software.

With Spline you can create 3D objects and scenes, apply materials and lighting, animate elements, and — crucially — make them interactive, responding to clicks, hovers, scroll, and other events. The results can be exported and embedded directly into websites and apps, so the 3D you design becomes a living part of a real interface rather than a static render. It supports real-time collaboration so teams can build scenes together, and it continues to add capabilities, including AI-assisted creation, that lower the barrier even further. The emphasis throughout is on making 3D feel like a natural extension of design work instead of a separate, arcane discipline.

Spline is used by web and product designers, creative developers, and brands that want to stand out with engaging, modern visuals — interactive 3D heroes, animated product showcases, playful UI elements, and immersive landing pages. As websites increasingly compete on experience and distinctiveness, the ability to add tasteful interactive 3D is a real differentiator, and Spline makes it attainable without a specialist or a steep learning curve. For designers who want to push beyond flat layouts and create something that feels dynamic and memorable, Spline provides a uniquely accessible gateway into 3D, turning what used to be an expert-only capability into a creative tool that a much wider range of people can actually use and enjoy.
