What it is

Spline is a web-based 3D design tool that enables users to create 3D objects, scenes, and interactive experiences directly in a browser. It is designed for designers, product teams, and creators who want to work in 3D without the complexity of traditional 3D software. The platform emphasizes real-time collaboration, allowing multiple users to work on a design simultaneously.

How it works

Real-Time Team Collaboration

Teams can invite members to work on 3D designs simultaneously. Users can set individual permissions, add comments, and share project links to collaborate on 3D scenes in real-time.

Creating Interactive Web Content

Designers create 3D scenes using the browser-based editor, adding interactivity through events and physics. The resulting designs can be exported as embeddable code snippets that integrate directly into websites and web applications.

Spatial Design for VisionOS

Users create interactive 3D content in Spline and bring it to Apple's VisionOS using Spline Mirror, enabling the creation of spatial computing experiences for Vision Pro.

Learning and Remixing

New users can explore and open existing examples from the library to understand 3D design concepts. The platform provides tutorials and a template library to help users learn and remix existing 3D designs.
