Spline
4.5
Spline is a browser-based 3D editor aimed at designers rather than at 3D specialists, with publishing straight to the web — an embeddable interactive scene rather than a rendered image. AI generation for models and textures is included, but the editor and the web export are the reasons to use it.

What it is good for
- Interactive 3D on a landing page without a WebGL project
- Designers who want 3D without learning Blender
- Product visuals that respond to scroll or cursor
- Collaborative scene editing in the browser
Strengths and trade-offs
Strengths
- Runs in the browser; nothing to install and easy to share
- Publishes an embeddable interactive scene, not just a render
- Approachable for designers coming from 2D tools
- Free tier is generous enough to ship small work
Trade-offs
- Not a replacement for Blender or Cinema 4D on complex work
- Embedded scenes carry a real performance cost on the page
- AI generation is secondary to the manual editor
Editors' review
3D for designers, published straight to the web
Spline's bet is that the obstacle to 3D on the web is the toolchain, not the idea. A browser editor with sensible defaults lets a designer build a scene and embed it the same afternoon, which is not true of the professional packages.
Interactivity is what distinguishes the output. A scene that reacts to scroll or cursor is a different product from a rendered image, and that is where the attention value of 3D on a landing page actually comes from.
Two warnings. It is not a professional 3D package and will not become one, and an embedded scene costs real bytes and GPU time — measure the page before shipping it to a performance-sensitive site.
Verdict
The practical way to put interactive 3D on a page. Check the performance budget before it ships.
