Mouse Tester

Check every mouse button, measure your double-click gap, run a clicks-per-second test, and get a polling rate estimate. Everything runs locally in your browser. Nothing is uploaded.

Buttons and movement
Press mouse buttons anywhere on the page. Back and forward appear on most mice; some drivers swallow them before the browser sees anything.

Double-click test
Click the pad twice, fast. Most systems count a double click at 500 ms or less between the two presses.

Click speed
Pick a duration, then click the pad. The timer starts with your first click and stops on its own; the counter freezes when time is up.

How to use

  1. Move the pointer and press buttons anywhere on the page. The five tiles count left, middle, right, back, and forward, and each tile lights up while its button is held.
  2. For the double-click test, click the pad twice, fast. The panel shows the gap between your last two clicks and how many pairs were fast enough to count as double clicks.
  3. For the click speed test, pick 1, 2, or 5 seconds, then click the pad to start the timer and keep clicking. The result freezes when the window closes.
  4. For the polling rate estimate, move the pointer in small steady circles over the page and read the Hz figure after a few seconds.

Frequently asked questions

Does the mouse tester collect anything?

No. Button presses, pointer positions, and timestamps are read inside your browser tab and nothing is recorded, stored, or sent anywhere. The page sets no cookies. Ad slots on the page are served by third-party networks, which follow their own privacy policies.

How accurate is the polling rate estimate?

Treat it as an estimate, not a specification. Browsers deliver mousemove events in batches and quantize their timestamps, so a mouse that reports 1000 times a second often shows a lower figure here. The estimate takes the median gap between your last few hundred movement events, discarding pauses and outliers first, so a few seconds of steady small circles give the most honest number your browser can produce.

What counts as a double click?

Most operating systems accept two clicks within about 500 ms as a double click, and the exact limit is configurable on each system. The panel shows the gap between your last two clicks so you can compare it against your own system's setting.

Why don't my back and forward buttons show up?

They are reported as mouse buttons 3 and 4 on most systems, and the tester counts them whenever the browser sees them. Some driver software and browser extensions intercept those buttons for history navigation first, so if their tiles never move, the presses are being consumed elsewhere.

Does this work on a touchpad or touchscreen?

Yes. Touchpads send the same button and movement events, so the tiles, double-click panel, and click speed test all work. Touchscreens count taps too, though a long-press or right-click gesture may open the browser's own menu instead of registering as a button.
