When a mouse starts acting weird (double-clicking, missed clicks, scroll wheel jumps), itโs surprisingly hard to prove whatโs happening โ especially when youโre trying to troubleshoot quickly or decide whether to replace hardware.
So I made a lightweight, browser-based mouse tester with instant visual feedback:
๐ฑ๏ธ Visual button map (Left / Right / Middle / Side buttons)
โก Double-click issue detection (helps spot unintended extra clicks)
๐ Scroll wheel jump/direction checks (catch โscrolling the wrong wayโ or jumping)
No install, runs in the browser, and designed to be fast and simple.
A startup from LOS ANGLES, the United States.

Mouse Tester combines a visual button map (left/right/middle/side buttons) with targeted diagnostics for two of the most common real-world issues: unintended double-clicks and scroll wheel jumping/direction problems. Itโs designed to be fast, simple, and instantly understandableโso users can confirm whatโs happening within seconds.
Mouse Tester is currently aimed at the general public and support use cases rather than enterprise accounts. Users typically include individuals troubleshooting peripherals, gamers, and IT/helpdesk staff who need quick browser-based verification. (If you have specific customer names or logos later, you can add them here.)
Mouse Tester focuses on the checks people actually need when a mouse feels โoffโ:
Clear visual feedback for every button press (including side buttons)
Practical double-click issue detection to spot unintended repeats
Scroll wheel jump/direction checks to catch erratic scrolling
Itโs also lightweight and straightforwardโno installs, no accounts, and a clean UI that gets you to a result quickly.
Mouse Tester is built for:
Everyday users troubleshooting mouse issues at home or work
Gamers who want to verify clicks, side buttons, and scroll behavior
IT/support teams who need a quick way to validate mouse input in a browser
Anyone buying/repairing peripherals who wants a simple verification tool
Mouse Tester started as a practical fix for a common problem: when a mouse begins double-clicking or the scroll wheel starts jumping, itโs hard to prove the issue quickly. The goal was to create a browser-based tester that makes mouse input visible and easy to diagnoseโso users can confirm the problem before changing settings or replacing hardware.
Mouse Tester is a web app built with a modern front-end stack:
Next.js (static export / no-backend deployment)
React + TypeScript
Tailwind CSS and shadcn/ui for UI components
Core diagnostics are implemented with standard browser mouse and wheel events.
Mouse Tester (mousetester.net) is a free, browser-based tool that reliably lets you check your mouse buttons, scroll wheel, click behavior, and polling rate without installing any software, making it a handy quick-diagnostic utility.
