Spline

Spline provides a comprehensive set of features for 3D design and interactivity. It includes real-time rendering, primitives and 3D modeling tools, and multi-platform exports. Users can create unique materials using a layer-based system or choose from a ready-made material library. The platform supports interactivity and motion through an event system, timeline animation, game controls, physics, and particles. Additionally, Spline allows integration of real-time data via variables, webhooks, APIs, and AI. For design, it offers an infinite canvas, frames, auto layout, color and strokes, snapping, and vector networks. Visual effects such as shadows, blurs, glass, and 3D projections enhance designs.

Spline is used for a variety of applications, including interactive websites, product design, brand and marketing campaigns, gamified experiences, 3D mockups, 3D logos, and animated characters. It is also applied in industrial and manufacturing contexts and for creating 3D icons. The platform enables teams to collaborate in real-time, with features like comments and link sharing. Spline supports shipping experiences to the web, iOS, and Android, with integrations for Webflow, Framer, Wix Studio, HTML/JS, React, Next.js, Swift, and Kotlin. It is suitable for designers and developers looking to integrate 3D content without extensive coding.

Spline offers a free tier, as indicated by the call-to-action 'Get started — it's free' on the page. The page does not provide detailed pricing information for paid plans, so only the availability of a free version is confirmed.
