Categories:
Spline is a browser-based 3D design platform with real-time collaboration for creating interactive 2D and 3D experiences deployable on web, mobile, and desktop.
🚀 Overview
Spline is a native web and desktop tool for designing interactive 3D scenes and animations in real-time, with seamless collaboration features. It combines intuitive 3D modeling, advanced effects, and code exports to bring immersive experiences to life without traditional software barriers.
This project solves the complexity and inaccessibility of professional 3D tools like Blender or Maya, which require downloads, high-end hardware, and steep learning curves. Spline makes 3D design as approachable as Figma or Canva, directly in the browser.
It's built for creative professionals, web developers, product designers, and teams at companies like Nike, Figma, and Shopify who need production-ready 3D for websites, apps, prototypes, and marketing.
The tool was developed to empower anyone to create web-native 3D content, fostering innovation in digital experiences through ease-of-use, AI assistance, and cross-platform exports.
✨ Key Features
- Real-time collaboration: Edit scenes together like Google Docs, with comments, workspaces, and team libraries.
- 3D design toolkit: Modeling, sculpting, booleans, particles, physics, materials, lighting, cameras, and Hana 2D canvas for interactivity.
- Interactivity & logic: Events (mouse, collision), states, actions (sound, video), variables, APIs, webhooks.
- AI generation: Text-to-3D objects, textures, style transfer (add-on credits). Upcoming: more AI tools.
