What is the Mouse Click Tester?

A Mouse Click Tester verifies that every button on your mouse — left, right, middle, back and forward — registers correctly and at the speed you'd expect. Toollyz Mouse Click Tester gives you a focused test area that captures pointer-down and pointer-up events, the wheel, double-clicks and pointer movement. Each click renders a color-coded ripple at the exact cursor position, the button counts increment live for left/right/middle/back/forward, a rolling clicks-per-second meter shows your click cadence, and the wheel-tick counter tracks scroll input. The right-click context menu is suppressed inside the test area so right-click testing actually works, and Pointer Events handle both mice and stylus/touch with the same API. Everything is read in your browser — your clicks are never sent anywhere.

How to use it

  1. Click anywhere in the test area to register a press — left, right, middle, back or forward.
  2. Watch the button counts increment and ripples appear at your cursor.
  3. Click twice quickly to detect a double-click; scroll the wheel to count ticks.
  4. Use Reset to clear counters, then run through every button to confirm your mouse is healthy.

Benefits

  • Live counts for left, right, middle, back and forward buttons.
  • Visual ripples at the cursor for every click, color-coded by button.
  • Double-click detection with a clear indicator.
  • Clicks-per-second (CPS) meter over a 5-second rolling window.
  • Scroll-wheel tick counter to verify your wheel.
  • Cursor coordinates inside the test area for precision checks.
  • Right-click context menu suppressed so right-click testing actually works.
  • 100% private — clicks stay in your browser.

Frequently asked questions

What does this mouse tester check?

Whether every button on your mouse fires events, how fast you can click (CPS), whether your double-click registers, and whether the scroll wheel produces ticks. It's the quickest way to catch a dying switch, a stuck button or a misbehaving wheel.

Why doesn't my right-click open the browser menu?

The test area calls preventDefault on contextmenu so right-click registers cleanly without showing the browser's menu. Right-click outside the area to bring the menu back.

How are back/forward (side) buttons detected?

If your mouse fires button 3 (back) or button 4 (forward) — most gaming and many office mice do — they show up in their own counters. If they never appear, your mouse may not expose them or your OS/driver is intercepting them.

What is CPS (clicks per second)?

How many clicks you registered in the last second, sampled with a short rolling window. Useful for testing gaming mice, mechanical switches and your own click cadence.

Why is double-click sometimes missed?

Operating systems treat two clicks as a double-click only when they happen within a configured window (often 300–500 ms). Click faster, or check your OS's mouse-speed setting.

Does it work with a trackpad or touch?

Yes. The tool uses Pointer Events, which cover mice, trackpads, pens and touch. Three-finger taps and gestures may not generate button events the way a physical mouse does.

Why doesn't my scroll wheel count when I scroll quickly?

Most wheels send multiple wheel events per spin; the counter increments per event. If you see no events at all, either the wheel hardware isn't sending input or the OS is consuming it (zoom shortcuts, gestures, etc.).

What about back/forward navigation in the browser?

The test area handles back/forward as plain buttons (3 and 4) and does not navigate. Outside the area, those buttons still control browser history as normal.

Does it work on mobile?

On a touch device, taps are treated as left-button clicks and ripples render at the touch point. Right-click, middle-click and scroll-wheel are mouse-specific and won't be available without a connected mouse.

Is this mouse tester free?

Completely free with no signup. Click as much as you like — privately in your browser.
