FPSMeter

Simple JavaScript library for sexy, fast, and themable FPS meter. It can measure:

  • frames per second
  • number of milliseconds between frames
  • number of milliseconds it takes to render one frame

FPSMeter uses performance.now() to more accurately measure rendering timing, with a fallback to +new Date().

The actual display rendering is optimized and chained to requestAnimationFrame (with a polyfill for older browsers), so it should be as smooth and as fast as possible. It also supports multiple instances on one page, has show/hide methods that also pause the rendering, and color heatmaps that make themes even more pretty!

Dependencies

None.

Compatibility

Works in IE7+ and all modern browsers.

Changelog

FPSMeter upholds the Semantic Versioning Specification.
