Our take
Spline brings 3D design into the browser with AI assistance, aimed at designers rather than 3D specialists. It is genuinely approachable, and web export is where it earns its place — interactive 3D on a site without a pipeline. Performance on visitor devices is the constraint people discover after building something impressive.
Worth it if
Designers adding interactive 3D to websites without learning a full 3D application.
Look elsewhere if
Production 3D for games or film, where the pipeline expectations are entirely different.
✨ Features
Text-to-3D
Generate 3D objects from text prompts with multiple variant options.
Image-to-3D
Convert front-facing 2D images into three-dimensional models.
Remix Variants
Create new variations from previously generated 3D objects.
Editor Integration
Refine generated assets directly within the Spline 3D editor.
It can, substantially, and it is the most common regret with browser 3D. Scenes that run smoothly on a development machine can be slow on mid-range phones, where most visitors are. Test on real low-end hardware, keep polygon counts and texture sizes disciplined, and measure the effect on load time before shipping.
How much does the AI assistance actually do?
It accelerates specific steps — generating materials, suggesting geometry, speeding up scene setup — rather than producing a finished scene from a prompt. The main value is lowering the barrier for designers who would not otherwise attempt 3D, not replacing the compositional judgement that makes a scene look good.
