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
