Spline: the collaborative 3D tool that transforms your browser into an interactive design studio
Real-time 3D modeling, optimized WebGL export, native Webflow/Framer integration. Zero installation, zero code, 100% browser.


01
Spline has killed the barrier to entry for 3D. Previously, creating a 3D experience for the web meant installing Blender (cockpit interface), struggling with Three.js (pure code), or paying for Sketchfab (heavy player). Spline? Web browser. Period. We model, we animate, we export in optimized WebGL. Real-time. Collaborative. Zero friction.
Why Spline has replaced our heavy 3D workflows
01 /
Modeling without installation
Open the browser, create. No €2000 Adobe Dimension license, no beast of a machine to run Cinema 4D.
02 /
Native WebGL export
Direct embed for React, Webflow, Framer, Vanilla JS. Your 3D scene loads in < 2 seconds. Responsive out of the box.
03 /
Real-time collaboration
Like Figma, but for 3D. Your teams work on the same scene simultaneously. In-context comments.
04 /
Native interactive animations
Mouse/scroll events, physics, particles. We create clickable 3D experiences without writing a line of JavaScript.
05 /
Integrated generative AI
Generation of 3D models and textures by prompt. Style transfer to apply artistic looks with a single click.
06 /
Webflow/Framer integration
Announced at the Webflow Conf 2023: native integration. We inject our 3D scenes directly into your projects. Zero code.

Why our teams use Spline ?
"Spline is the democratization of 3D. We create hero sections with interactive 3D objects in 2 hours, where it previously took 3 days with a custom Three.js pipeline.”

03 /
Smooth animation timeline
Keyframes, animation curves, interactive states. Animate your objects like in After Effects.
04 /
Physics & Particles
Gravity, collisions, particle emitters. Simulate realistic physical behaviors in real time.
05 /
Multi-platform export
Code snippets for React/Three.js/Vanilla, native iOS, Android (announced 2024), Apple Vision Pro (spatial mode).
06 /
AI Generate & Style Transfer
Generate 3D models from text prompts. Apply artistic styles to your scenes using AI.
Spline isn’t the only tool in our kit
Spline vs. its cousins
We have done our research for you, and here is the verdict.
Is there really nothing to install?
Yes. Web browser only. Chrome, Safari, Firefox. Even on iPad.
Can I export to Webflow?
Yes, native integration announced at the Webflow Conf 2023. Embed directly via the Spline component.
Does it replace Blender for everything?
No. For photo-realistic rendering or complex animation, Blender remains king. Spline = interactive web experiences.
Are the files heavy for the web?
No. Optimized WebGL export. Our 3D scenes load in < 2 seconds. Native lazy loading.
Does AI really generate 3D models?
Yes, experimental feature. Text prompt → 3D model. Variable quality, but impressive for rapid prototyping.
