Spline - 3D Design tool in the browser with real-time collaboration

Spline is a free, browser-based 3D design tool that eliminates software installation. It enables full creative workflows including modeling, material editing, animation, and interactive design directly online. Real-time collaboration allows teams to edit 3D projects simultaneously, boosting remote productivity. Built-in AI assists by auto-generating base models and creating 3D elements from text descriptions, freeing designers for creative work. Unlike traditional 3D tools, Spline is lightweight and cloud-rendered, running smoothly on low-end devices without high-end GPUs. Results can be embedded directly into websites or exported as lightweight code supporting hover effects and parallax scrolling. A rich preset library aids beginners, while advanced node editors allow custom logic for professionals. Spline serves web design, UI/UX, brand marketing, e-commerce product showcases (360-degree rotation), interactive landing pages, and education for virtual labs. It suits independent designers, small studios, and large enterprise teams. Launched in 2020, Spline became a popular 3D plugin in the Figma community, surpassing 10 million users by 2024. Powered by WebGL and WebAssembly, it unifies AI generation with real-time physics across platforms, democratizing 3D content creation.
