Spline

Spline is a web-based, real-time collaborative 3D design platform for creating production-ready interactive experiences in the browser. It supports 3D modeling, animation, materials, interactivity, and multi-platform exports, with a focus on collaboration and live editing.

Spline provides an in-browser 3D design environment with real-time collaboration, allowing users to model, texture, animate, and add interactivity to 2D/3D scenes. It includes a node-like materials system with multi-layer capabilities, an event system for interactivity, timeline-based animation, and support for variables, data integration via webhooks/APIs, and AI generation (AI credits). Outputs can be exported to Web, iOS, and Android, and teams can collaborate via comments, sharing, and live edits. The platform also offers multiple editors (3D design editor, 2D Hana editor), a library of materials and assets, and a workflow that aims to ship production-ready experiences directly from the browser.

Who it’s for: Design teams and product teams seeking a collaborative, in-browser 3D design tool to create production-ready interactive experiences for websites, apps, and digital products.
