About
Spline is a tool for creating interactive 3D for websites and apps, with AI assistance. You can connect an agent such as Claude, ChatGPT, Cursor, Codex, or one you built, through Spline MCP Tools. The agent can read the scene, write to it, frame a view, and check the result. Every change lands as an operation in a live file, so your team can watch edits happen and undo, comment, or take over at any point.
The editor covers modeling with primitives, booleans, sculpting, and 3D generation. It also includes layered materials, lights, and post-processing, plus states, keyframes, events, and physics for animation and interaction. Agents and designers work in the same file, so an agent can build a first version and your team can refine it.
When a scene is ready, you can publish it to the web, embed it with React, or run it natively on iOS and Android. Each platform uses its own native renderer, so scenes keep their interactivity and performance.
