Spline

Spline is bringing 3D design to the web design world by offering a browser-based tool that makes creating interactive 3D experiences dramatically more accessible than traditional 3D software. For agencies looking to differentiate their web projects with immersive 3D elements, product visualizations, or animated scenes, Spline provides a Figma-like collaborative experience in three dimensions — no Cinema 4D expertise or Blender learning curve required.

The interactive capabilities are what make Spline particularly exciting for agencies. Unlike static 3D renders, Spline scenes can respond to user interactions — hover effects, click events, scroll-triggered animations — and export directly to web formats or React components that developers can drop into production sites. This means agencies can offer clients interactive 3D product showcases, animated hero sections, or immersive brand experiences that would traditionally require specialized WebGL developers. Real-time collaboration means designers and developers can work on 3D scenes simultaneously, just like they would in Figma.

Compared to Blender or Cinema 4D, Spline is far less powerful for complex 3D modeling and rendering, but orders of magnitude more accessible for web-focused 3D work. Compared to Three.js or Babylon.js coded approaches, Spline provides a visual editor that non-developers can use while still exporting clean, embeddable output. For agencies that want to add 3D to their web design offerings without hiring dedicated 3D specialists, Spline lowers the barrier to entry dramatically.
