Spline

Spline is a 3D design tool that runs in the browser and lets users model, animate, and build interactive scenes without specialized rendering software. It provides an approachable editor for creating objects, applying materials, and adding animation and interactivity that can be embedded directly into websites and apps.

The product is aimed at designers, developers, and creative teams who want to add 3D and spatial elements to digital experiences. Its strengths include real-time collaboration, an intuitive interface for people new to 3D, and export options for the web, along with AI-assisted features that generate 3D content from text prompts.

Spline follows a freemium model, offering a free tier with paid plans that add collaboration, storage, and advanced capabilities. Founded in 2020, it has grown quickly as demand for interactive 3D on the web has increased.
