lottie

This turns "make me a loading spinner animation" into actual Lottie code through your AI coding agent. Lottie is the format apps use for lightweight vector animations, and creating them normally means After Effects and a plugin. diffusionstudio/lottie installs as a skill for agents like Claude Code, then converts an SVG or a plain-text description into working animation code you can drop into web, React Native, iOS, Android, or Flutter.

Setup is one command, npx skills add diffusionstudio/lottie, and you're generating animations by prompting. There's nothing to host and no account. Because it produces standard Lottie JSON, the output plugs into the same players and tooling you'd already use. The whole thing is MIT-licensed and free.

Developers who need simple animations but don't have a motion designer, or don't want to learn After Effects, are the target. It won't replace a real animator for complex, hand-crafted motion work. For spinners, icon transitions, and straightforward UI animation, it's a fast path from idea to code without leaving your editor.

The catch: it leans on your AI agent, so the quality of what you get tracks the quality of your prompt and your model. Intricate animation is still beyond what a text prompt produces cleanly, this shines on the simple-to-moderate stuff. Think of it as a head start, not a finished motion-design studio.
