How to detect redraw rate (fps) of a css animation?

I'm interested in the fluency of my CSS animations. As some extra points:

  • I'm mostly interested in performance on mobile devices (WebKit),
  • It would help if data could be gathered during normal operation (with real users doing real things).
Solution

  • Chrome Beta for Android supports getting FPS by setting flag in chrome://flags
