What is Spline?
Spline is a browser-based 3D design tool for modeling, animating and publishing interactive 3D scenes for websites and apps. It covers primitives, booleans, sculpting and AI 3D generation, plus layered materials, lighting, post-processing, states, keyframes, events and physics.
Teams work in the same live file with comments and undo. Through Spline MCP, AI agents such as Claude, ChatGPT, Cursor and Codex can read, write and view scenes, and designers can then edit what the agents built. Finished scenes can be shared as a link, embedded, exported as code, or built for native platforms: SwiftUI views and Xcode projects for iOS, and Jetpack Compose views or APK/App Bundle builds for Android.
Spline suits web designers, product teams and developers who want real-time 3D without a traditional desktop 3D package. Its free plan is for personal use, and paid seats add AI credits and more export options.
