Create interactive 3D scenes for web and product design
Spline is a web-based 3D design tool for creating interactive scenes, prototypes, and lightweight 3D assets aimed at designers and frontend teams; it yields embeddable WebGL/HTML exports and has a freemium model with paid Pro/Team tiers for collaboration and higher export limits.
Spline is a browser-first 3D design and prototyping tool that lets designers build interactive WebGL scenes, 3D UI components, and lightweight animations without code. Its primary capability is real-time scene editing with direct Web export and embeddable iframes, distinguishing it by focusing on web-native 3D rather than heavyweight offline render pipelines. Spline serves UI/UX designers, product teams, and front-end developers who need interactive 3D prototypes and small in-page assets. Pricing is accessible with a free tier for learning and limited exports, plus paid Pro and Team plans that unlock collaboration and higher export quotas.
Spline is a browser-based 3D design and prototyping application founded in 2020 and positioned as a tool for web-native 3D experiences. It focuses on letting designers and product teams create interactive 3D scenes, animations, and components that can be exported as WebGL (Three.js) or embedded via iframe. Spline’s core value proposition is bridging design and the web: instead of producing render-heavy assets for offline compositing, it produces lightweight, interactive assets meant to run in browsers and integrate into web interfaces and prototypes.
The feature set centers on a real-time editor, interactive behaviors, and export options. The editor supports primitives, boolean operations, meshes import (OBJ/GLTF/GLB), material editing with PBR-like sliders, and keyframe animation timelines for per-object transforms. Interactions let you add on-hover, on-click, and scroll-linked events that trigger animations or navigate scenes; these are exposed as event behaviors you can assign in the UI. Spline exports include embeddable iframes, direct GLB/GLTF downloads, and a Three.js-ready scene JSON, plus an API for runtime parameter updates so developers can change object properties from JS. Collaboration features add shared access, commenting, and version history in paid plans.
Spline’s pricing uses a freemium model. The Free plan lets users create scenes, use basic export/embed capabilities, and keep up to a small number of projects (limitations and exact project counts can change). Paid plans start with Pro (monthly price on the website; includes private projects, higher export bandwidth, team seats, and priority support) and Team/Enterprise options that add SSO, team management, and increased usage quotas. The free tier is suitable for learning and small demos, while Pro is intended for solo designers who need private projects and expanded export limits; Team is priced per-seat with collaboration and admin controls. For the latest exact monthly rates see Spline’s pricing page as they update tiers periodically.
Who uses Spline in production workflows? Product designers use it to prototype interactive 3D UI components and reduce handoffs to engineering, while frontend developers embed Spline iframes or consume exported GLTF/Three.js scenes to add 3D interactivity to landing pages. Example job-title use-cases: a Senior Product Designer creating an interactive hero animation that runs at sub-1MB on the homepage, and a Frontend Engineer integrating a parameterized Spline scene to control product configurators. Compared to a competitor like Figma (with FigJam and 2D-focus) or Blender (heavy offline 3D), Spline sits between them by offering web-first interactivity and easier embedding than generic 3D tools.

Choose Spline over Framer if you need exportable WebGL scenes and GLB/Three.js assets rather than 2D-first prototyping.
