Best for

Designers who want interactive 3D scenes without learning a full 3D suite.

Why it deserves attention

Spline makes 3D approachable with a familiar layers panel, drag-and-drop objects, materials, and scene states that can respond to mouse or scroll events. Scenes can be embedded on a website or exported for product prototypes. Complex geometry and rendering still hit browser limits, and serious 3D work eventually needs Blender or Cinema 4D.
