Text-to-lottie is an open-source harness for generating production ready Lottie animations with claude code/codex or any other coding agent supporting skills.

Quick Start

Install the skill:

npx skills add diffusionstudio/lottie

Then ask your coding agent to generate a Lottie animation using text-to-lottie.

Example prompt:

Create a Lottie animation from the SVG path in https://github.com/JaceThings/SF-Hello/blob/main/SVG/hello-en.svg. Reveal the path with an animation that follows the natural path direction. Apply a premium apple themed gradient to the path. Use ease-in-out timing, a transparent background, and preserve the original SVG geometry.

The agent will setup a harness and can inspect/edit the generated lottie in the with the included player.

Prompt guide

1. Ground the model

Provide SVGs, real-world data, or screenshots whenever possible. Results are significantly better when the animation is based on concrete assets.

2. Use motion design terminology

Describe timing and movement using motion design language like ease-in, ease-out, and ease-in-out.

3. Think like a camera operator

Professional motion graphics often rely on camera movement. Include camera pushes, pans, zooms, and rig-like motion in your prompt. The agent can simulate these through group transforms.

4. Request the controls you need

By default, outputs usually only expose a background color control. If you want to customize other properties, explicitly ask the agent to create controls for them.

5. Specify FPS and duration

If your animation requires a specific frame rate or length, include the desired FPS and total frame count in the prompt.

Using the Generated Animation

Generated animations can be used directly as Lottie JSON files or imported into After Effects for further refinement.

Web / vanilla HTML

<script src="https://unpkg.com/lottie-web/build/player/lottie.min.js"></script>

<div id="anim"></div>

<script>
  lottie.loadAnimation({
    container: document.getElementById("anim"),
    renderer: "svg",
    loop: true,
    autoplay: true,
    path: "/animations/my-animation.json"
  });
</script>

React Native

npm install lottie-react-native

import LottieView from "lottie-react-native";

export default function Loader() {
  return (
    <LottieView
      source={require("./animation.json")}
      autoPlay
      loop
      style={{ width: 200, height: 200 }}
    />
  );
}

iOS Swift

import Lottie

let animationView = LottieAnimationView(name: "animation")
animationView.frame = view.bounds
animationView.contentMode = .scaleAspectFit
animationView.loopMode = .loop
view.addSubview(animationView)
animationView.play()

Android Kotlin

val view = findViewById<LottieAnimationView>(R.id.animationView)
view.setAnimation(R.raw.animation)
view.loop(true)
view.playAnimation()
