About Frame Rate Test

Frame Rate Test is a small set of free browser tools for checking how smoothly your screen and browser draw motion: live FPS, an estimate of the refresh rate, a frame time graph, a stutter counter and UFO-style motion tests.

How we build the tools

Everything runs in your browser with standard web APIs. We only show numbers the browser can actually measure and we explain the limits on each page.
