Features

  • Browser-based 3D creation

    Spline runs in the browser and provides tools for creating interactive 3D scenes for websites and apps.

  • AI-assisted scene building

    AI can generate 3D content, while agents can read scenes, write changes, frame views and inspect results through MCP tools.

  • Editable 3D scene tools

    The editor provides primitives, booleans, sculpting, 3D generation, layered materials, lighting and post-processing controls.

  • Animation and interaction

    States, keyframes, events and physics provide controls for animation and interactive behavior inside a scene.

  • Cross-platform publishing

    A scene can publish to the web, embed through a viewer, export code, or run natively on Apple and Android.

What users say

Pros

  • Website integration is far stronger than Blender's for interactive 3D pages.
  • First projects feel easy and quick, even with no prior 3D experience.
  • Toon shaders can make 3D animations read like flat 2D vector graphics.
  • Modeling and animating in the browser has become strikingly capable.

Cons

  • Timeline animation suffers from awkward controls, missing basics and phantom keyframes.
  • Complex scenes can add enough web data to slow pages down.
  • Ambient lighting can stop affecting objects after imported geometry changes scene order.
  • Refund requests can be refused after mistaken purchases or automatic renewals.
