Keyframes is a Facebook library consisting of an ExtendScript tool that extracts vector animation data from Adobe After Effects files into JSON, plus rendering libraries for Android and iOS. It enables high-quality, vector-based animations with a minimal file footprint.
Use cases
- play after effects animations in an android app
- render vector animations on ios from a json file
- export after effects shape animations to a data format
- add lightweight animated illustrations to a mobile app
- convert ae shape layers to mobile animation assets
When to choose
- you need vector-based animations exported from After Effects for Android or iOS
- you want minimal file size for complex shape and path animations
- you are maintaining an existing app already built on Keyframes
When to avoid
- starting a new project - the repo is archived and unmaintained
- you need modern tooling or community support - consider Lottie instead
- you need animations beyond the AE constraints Keyframes imposes
