What is Spline?

Spline is a browser-based 3D design tool that brings collaborative 3D modelling into the same workflow designers already use in Figma. It runs entirely in your browser, so there is no software to install. You can model, animate, and export interactive 3D scenes for the web, with AI features to generate scenes, textures, and animations from text prompts. The tool exports clean, web-ready code that works with React and Vue, making it possible to add interactive 3D to websites in an afternoon instead of weeks. Spline is designed for designers, web developers, marketers, and 3D enthusiasts who want to add interactive 3D to products without learning a heavyweight pipeline like Blender. It is especially useful for landing pages, hero sections, product visualisations, and interactive marketing campaigns.
