Click, scroll and move your mouse anywhere in this box. Right-click is safe. The menu is suppressed here.
This free online mouse test checks that every part of your mouse works: left, right and middle buttons, the back and forward side buttons, the scroll wheel in both directions, and movement tracking. Each control lights up on the on-screen mouse the moment your real mouse reports it, so you can confirm a new mouse, diagnose a faulty one, or check that side buttons are being detected. All in the browser with nothing to install.
Click each button in turn and watch the matching area of the on-screen mouse highlight. Scroll the wheel up and down to confirm both directions register, and press the wheel itself to test the middle click. Move the pointer around the tracking area to check movement is smooth and reported without gaps. Buttons you've already pressed stay marked so you can see what's left to test.
Many mice have two extra buttons on the thumb side, usually mapped to back and forward. Browsers expose these as button 3 and button 4, and this test detects them directly. Press each side button and the corresponding marker lights up. If a side button doesn't respond here, it may be disabled in your mouse's software, unmapped, or physically faulty.
Right-clicking normally opens the browser's context menu. Inside the test area that menu is suppressed so you can test the right button freely without a pop-up appearing each time. The right button still registers as pressed and released just like the others.
The test only reacts to the mouse events the page already receives, clicks, wheel and movement. Nothing is recorded or uploaded. If a button or the wheel doesn't respond, try a different USB port or receiver, check the mouse's own software for remapped buttons, and rule out a loose cable before assuming the mouse has failed.
Click each button on your mouse and watch the matching part of the on-screen mouse light up. Left, right, middle (wheel click) and the two side buttons each have their own marker, and buttons you've already pressed stay highlighted so you can see which ones are left to check.
The context menu is intentionally suppressed inside the test area so you can press the right button repeatedly without a pop-up appearing each time. The right button still registers as a proper click, you'll see its marker light up.
Yes. Browsers report the thumb buttons as button 3 and 4, and the test detects them directly. Press each side button and its marker lights up. If nothing happens, the button may be unmapped or disabled in your mouse's software rather than broken.
Scroll the wheel up and down inside the test area. The up and down indicators light as each direction registers, and a running count shows scroll events. Press the wheel straight down to test the middle click, which appears as its own button.
No. The test runs entirely in your browser and only reacts to the mouse events the page already receives. Nothing you click or scroll is stored or transmitted, and there's no sign-up.
