LottieFiles

LottieFiles is the central ecosystem for Lottie animations — a community library of 400,000+ animations, an online editor, and integrations with Figma, After Effects, Webflow, and Framer. Lottie files are up to 600% lighter than GIFs and render natively on iOS, Android, and web. The platform also handles team collaboration, version control, and the newer dotLottie format for even smaller file sizes.

Spline

Spline is a browser-based 3D design tool that makes interactive 3D accessible to web designers without requiring Blender or Three.js skills. You get parametric modeling, timeline animation, event-driven states, and one-click embedding for websites — all with real-time collaboration. An optional AI add-on generates 3D objects and textures from text prompts.

Cavalry

Cavalry is a procedural 2D animation tool built by former Mainframe studio veterans in Manchester. Instead of keyframing everything manually, you connect nodes to define repeating behaviors — making it ideal for data-driven motion, generative art, and complex animation at scale. Used by Apple, Canva, Google, Nike, and Buck; the free Starter tier is permanent.

Womp

Womp is a beginner-friendly browser-based 3D modeler built around 'Goop' — a liquid modeling system where objects blend organically as you push and pull primitives together. It renders at 4K with PBR materials, supports real-time collaboration, and connects directly to a 3D printing service for physical output. Compared to Spline (which targets web embedding), Womp skews toward art-making and fabrication.
