Spline is a 3D design tool built specifically for web designers and developers who want to add interactive 3D elements to their projects without the steep learning curve of traditional 3D software like Blender or Cinema 4D. It runs in the browser and provides a simplified interface focused on the types of 3D objects and interactions that are most useful for web design.
The export workflow is one of Spline's strongest features. You can export a 3D scene as a web component, an iframe embed, or a React component, and it renders in the browser using WebGL. This makes it practical to add 3D hero sections, product visualizations, and interactive elements to websites without writing WebGL code directly.
For web designers, Spline is most useful for creating hero section 3D elements, animated backgrounds, and interactive product visualizations. The learning curve is significantly lower than traditional 3D tools, and the web export workflow means you can go from design to deployed 3D element in a day.
For developers who want to add 3D to a React application, the Spline React component makes integration straightforward. The 3D scene is hosted on Spline's CDN, so there is no need to manage 3D asset files in your own repository.
Free tier allows unlimited public projects with Spline branding on exports. Pro plan at 9 dollars per month removes branding and adds private projects. Team plan at 17 dollars per user per month for collaboration features.
