Spline

Spline is a browser-based 3D design tool. It lets designers create interactive 3D scenes without coding. It solves the high barrier to entry for real-time 3D web design.

Features

• Real-Time 3D Editing: Users edit 3D objects directly in the browser. Changes appear instantly without reloading or compiling.
• Interactive Events System: Designers attach hover, click, and scroll triggers to objects. No JavaScript knowledge is required.
• Web Export & Embed: Scenes export as lightweight JavaScript snippets. These embed directly into websites, Webflow, or Framer projects.
• Multiplayer Collaboration: Multiple users edit the same file simultaneously. Cursor presence and live syncing work like Figma-style co-editing.
• Asset Library & Variables: Built-in 3D components, materials, and reusable variables speed up production. Teams maintain design consistency across scenes.

Use Cases

• For Product Designers: Prototype animated 3D UI components for apps without handing off to a developer.
• For Marketing Teams: Build interactive product showcases that embed directly into landing pages.
• For Agencies: Deliver client-ready 3D hero sections using Spline-to-Webflow export workflows.
• For Developers: Use the Spline Viewer JavaScript library to load and control 3D scenes programmatically.

Spline makes browser-based 3D design accessible to non-technical creators. It bridges the gap between visual design tools and interactive web experiences.
