Collaborative 3D design in real time

Yes! Spline’s free plan gives you access to powerful tools for prototyping interactive 3D designs. Whether you’re creating early-stage concepts or detailed mockups, you can design, animate, and test your ideas all in your browser, without any coding knowledge.

You can start from a blank canvas, remix an existing prototype from the Spline Community, or use ready-made shapes and components. Add animations, materials, and lighting to test interactions and behaviors directly within your working scene.

Spline offers a real-time 3D design environment that’s perfect for fast iteration. You can create product concepts, simulate functionality with interactions, and share prototypes easily with stakeholders. Everything happens in the browser with no complex tools required.

Spline supports importing assets like .OBJ, .FBX, .glTF, and .STL. You can also include images (.JPG, .PNG), vector graphics (.SVG), and audio or video elements to make your prototype feel more realistic. Scenes can be exported or embedded for feedback and testing.

Yes! Product designers and UX teams use Spline to explore new ideas, visualize product behavior, and present interactive concepts. It’s a fast, visual tool that fits right into modern design workflows and supports collaboration and iteration.

Not at all. Spline’s interface is user-friendly and made for designers, not 3D specialists. You can create, animate, and share prototypes without needing to write code or master traditional 3D modeling software.
