Spline brings 3D to web designers. In a browser editor that feels more like Figma than Blender, you create shapes, materials, lighting, and animations, then add interactions such as hover effects and clicks. Scenes can be published as links, embedded in websites, or exported to code, and they run in real time in the browser. It’s used for product landing pages, interactive hero sections, games, and design prototypes.
Collaboration and AI features set it apart from traditional 3D tools. Multiple people can edit a scene at once with comments and version history. AI tools can generate 3D objects and textures from text, help with animation, and create scenes from prompts. Physics, particles, and state-based interactions add depth, and integrations with Figma let designers bring in 2D elements.
Spline has a free plan with limits and paid plans for teams with more projects, exports, and features. Complex scenes can be heavy on performance for web visitors, so optimization matters. It’s less suited to detailed modeling or film-quality rendering than Blender or Maya. Three.js is the code library behind many web 3D experiences, Rive handles interactive 2D animation, and Vectary and Womp are similar browser 3D tools. Spline suits designers adding 3D to websites.
