Spline is a browser-based, real-time collaborative 3D and 2D design tool built for teams shipping interactive web experiences. It exposes an API and supports self-hosting, making it composable within existing front-end stacks. Scenes can be embedded directly into React, Next.js, or plain HTML/JS projects, and exported for native mobile targets via Swift (iOS) and Kotlin (Android). The platform includes an AI-powered agentic design layer for programmatic 3D generation and editing, alongside a runtime engine that handles events, states, physics simulations, and particle systems — all rendered in the browser without additional dependencies. Integration with no-code platforms (Webflow, Framer, Wix Studio) is also supported for hybrid workflows. Pricing is freemium: a free tier is available, with paid seats starting at $12/seat/month (billed annually).
