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


01
Spline has killed the entry barrier to 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 optimised WebGL. Real-time. Collaborative. Zero friction.
Why Spline has replaced our heavy 3D workflows
01 /
Modeling without installation
Open the browser, create. No Adobe Dimension license at €2000, no war machine to run Cinema 4D.
02 /
Export Native WebGL
Direct embed for React, Webflow, Framer, Vanilla JS. Your 3D scene loads in less than 2 seconds. Automatic responsive.
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.
03
Why our teams useSpline ?
"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.”

We anticipated your questions.
It is known that entrusting your design to an external team,
raises some questions. Here are our answers.
Is it really without installation?
Can I export to Webflow?
Does it replace Blender for everything?
Are the files heavy for the web?
Does AI really generate 3D models?
