The appeal of Spline is immediate: 3D objects in the browser, no Blender required, paste a snippet and your marketing hero section has a rotating orb. It's not hard to see why it became the default choice for a certain kind of agency website around 2022 and has stayed there.
Spline's model is parametric 3D: you push and pull primitives, apply PBR materials, and set up event-driven states that respond to scroll or hover without writing any Three.js. The editor feels genuinely approachable if you've spent time in Figma or similar tools. Real-time collaboration works. The Webflow and Framer integrations are legitimately good, and the Hana tool on the side now offers 2D vector design in the same environment.
The catch is performance. This comes up constantly in community discussions, and it's not a fringe complaint: Spline scenes can be expensive on the GPU, and they're brutal on mobile. Low-end Android phones, older iPhones, and users on slower devices will often get a degraded or broken experience. To ship something that doesn't tank Core Web Vitals, you often end up making the scene much simpler than what you designed, which defeats some of the purpose. The WebGL rendering in the browser also diverges from what the editor preview shows you, so what you see is not always what gets delivered.
The AI 3D generation feature, marketed heavily, underdelivers in practice. Distorted outputs are common enough that most working designers ignore it and stick to manual modeling.
For teams doing modest 3D for desktop-first sites (a tasteful floating object, a subtle scene behind a headline), Spline is genuinely the fastest path there. For anyone who needs mobile reliability, sustained performance, or serious modeling depth, the ceiling arrives quickly. Womp has more interesting organic modeling; Unicorn Studio does GPU-accelerated effects more efficiently for most web use cases.
Free plan includes the Spline watermark. The $15/month Starter plan removes it. Pro is $25/month for unlimited editors and code exports.

Spline brings 3D shapes to its 2D Hana canvas
Spline's Hana canvas can now convert any 2D vector shape into a lit, material-aware 3D object in a single step — depth, rotation, and environment maps included — while the original shape stays fully editable in real time.
