What this site is

ClickSpeedTest.info hosts free tools for measuring mouse and keyboard input: click speed in clicks per second, spacebar pressing speed, keyboard key registration, and related diagnostics. Every tool runs entirely in your browser. There is no sign-up, nothing to install, and no result is uploaded anywhere.

Alongside the tools are guides covering clicking techniques, input hardware, and how automation software actually works. The aim is that someone leaves knowing why their number is what it is, not just what it is.

How the tools measure

Most tests in this category are a counter and a timer. These try to be a little more careful, and the differences are stated on each page so you can check them:

• Keyboard auto-repeat is excluded. Holding a key down makes your operating system fire repeated keystrokes automatically. The spacebar test detects those events, discards them, and shows you how many it threw away — which is why its scores are lower, and more honest, than counters that simply increment on every keypress.
• Key chatter is detected. The keyboard test flags a key when it sees a press-release-press cycle faster than a human can physically produce, which catches a worn switch that a light-up-the-key tester cannot see.
• Clicks are recorded second by second. The CPS test stores each individual second of a run rather than only the total, which exposes the gap between an opening burst and the rate a hand actually sustains — commonly 2–3 CPS, and invisible in a single average.
• Hardware latency is separated from human latency. The reaction time test breaks a score into display refresh wait, panel response, mouse polling and event handling, because a 60 Hz monitor with a 125 Hz mouse adds roughly 25–45 ms that has nothing to do with your reflexes.
• Scripted input is discarded. Browsers mark events created by scripts as untrusted, and the tests ignore those, so in-page automation cannot inflate a score. What a browser cannot detect is a separate program driving the operating system — and the relevant pages say so plainly rather than implying a guarantee.
• Timing is per-event. Individual timestamps are recorded, which is what makes the rhythm traces and consistency figures possible.
• Results stay on your device. Personal bests are kept in your browser’s local storage. Clearing your browser data clears them.

How the guides are written

A few rules the content is held to:

• Say when something does not work. The auto clicker and auto key presser pages exist largely to explain that a browser cannot send input to another application, because a great many pages in that category imply the opposite.
• No invented testing. No fabricated benchmark results, no made-up statistics, and no claims of hands-on testing that did not happen.
• No download recommendations that cannot be verified. The auto-clicker software category has a poor safety record, so those pages give selection criteria and point to operating-system features and open-source tools instead of linking to binaries.
• Corrections get made. If something here is wrong, tell us and it will be fixed.

Where the technical claims come from

Statements about how browsers and operating systems behave are taken from primary documentation rather than from other websites in this category, and the relevant pages link to it directly. The main references used across the site:

• MDN Web Docs — KeyboardEvent.repeat, for identifying operating-system auto-repeat.
• MDN Web Docs — Event.isTrusted, for separating real input from scripted input.
• MDN Web Docs — Performance.now(), for the deliberate reduction in timer precision noted above.
• Microsoft Learn — SendInput, for how desktop automation injects input at the operating-system level.
• Microsoft Learn — GetDoubleClickTime, for the Windows double-click recognition threshold.
