Your team and agents,
building and shipping in 3D
Spline is a 3D design tool in the browser, where your team and its agents build in one shared editor.
From prompt to production in one file
Your agent
Claude, ChatGPT, Cursor, Codex, or one you built. Anything that speaks MCP.
Spline MCP
Tools to read the scene, write to it, frame a view and look at the result. Read the setup guide.
The editor
Every change lands as an operation in a live file. Your team sees it happen, and can undo, comment or take over.
Everywhere
Publish to the web, drop it into React, or run it natively on iOS and Android.
Where ideas become
production-ready experiences



Mars Rover
A Mars game with two rovers to drive across the dunes.
Everything you need to build in 3D
- ModelPrimitives, booleans, sculpting and 3D generation.
- Materials and lightLayered materials, lights and post-processing.
- Animation and interactionStates, keyframes, events and physics.
- PerformanceHigh-performance real-time 3D.
Or ask an agent, in the editor or over MCP.
Agents build. Designers refine.
The agent gets the scene to a first version fast. Your team picks it up in the same file and takes it the rest of the way.
- Same fileThe agent builds in the editor your team already uses. Nothing to import or rebuild.
- Fully editableEverything it makes is a regular Spline object: select it, restyle it, animate it.
- Back and forthHand the next pass back to the agent, or take over by hand at any point.
One scene. Web, Apple and Android.
Ship the same file to a website, an iPhone app or an Android app. Each platform gets its own native renderer, so scenes keep their interactivity and performance.
WebWebGPU · WebGL
Publish a link, embed the viewer, or export code for your stack and host it yourself.
AppleMetal
Add a native SwiftUI view to your app, or generate an Xcode project ready for the App Store.
AndroidVulkan
Add a native view with Jetpack Compose, or build an APK or App Bundle straight from Spline.
Why teams build with Spline
“I wanted to do something really cool with 3D, really bring our brand to life, and Spline was the only tool that would let me do that.”

“Before Spline, we would need a developer just to handle the 3D integration. Now designers can focus on crafting assets, and engineers don’t have to rebuild them from scratch.”

“Spline is very easy and fast to learn. The learning curve is low, even junior designers can step in and integrate 3D experiences into a Webflow project.”
