## What it is
Lottie is a family of libraries by Airbnb that parses Adobe After Effects animations exported as JSON via the Bodymovin plugin and renders them natively on Android, iOS, Web, React Native, and Windows. It lets designers ship animations directly without engineers recreating them by hand.

## Use cases
- render after effects animations in an android app
- play lottie  animations on ios
- add animated illustrations to a website
- show animated loading spinners in react native
- ship designer-made animations without hand-coding them
- render vector animations from bodymovin exports

## When to choose
- you need to display After Effects animations natively on mobile or web
- designers want to ship animations without developer reimplementation
- you need lightweight, scalable vector animations instead of GIFs or videos

## When to avoid
- you need to author animations from scratch in code rather than render exported ones
- your animations come from tools other than After Effects without a Bodymovin export
- you need video playback or complex runtime-generated animation logic

## Facets
- artifact type: library
- maturity: stable
- function: animation, ui-components, graphics
- domain: mobile-development, web-development, frontend, cross-platform
- platform: cross-platform
- tags: after-effects, bodymovin, lottie, react-native, -animations, motion-graphics, android, ios, web-server, mobile
