Why this site exists
Click speed tests are a small internet tradition: a quick, surprisingly competitive way to compare raw hand speed with friends or to warm up before a gaming session. Many of the existing test sites are slow, cluttered with ads or vague about what they do with your data. ClickStorm is the opposite: fast pages, honest measurements and everything running locally in your browser.
The site covers the whole family of tests people actually search for: the classic CPS test with durations from 1 to 100 seconds, dedicated timed pages like the 10 second benchmark, technique tests for jitter clicking and butterfly clicking, plus a reaction time test, an aim trainer and a spacebar counter.
How the measurements work
Every test counts real input events the moment they happen, with no smoothing or rounding tricks. Timers are driven by your browser's high-resolution clock, and results are calculated the instant a run ends. Personal bests are saved in your browser's localStorage so your record is waiting for you next time, and nothing you do here is ever uploaded. Read more on the privacy page.
