Mouse Tester

About

A lightning-fast, zero-dependency mouse tester running natively in your browser.

Test your mouse buttons, scroll wheel direction, and detect faulty double-clicks instantly right from your browser window.

✨ FEATURES

• Instant Recognition: Move your mouse over the extension to wake it up, and your clicks will instantly map to the on-screen visualizer.
• Hardware Agnostic: Supports standard Pointer Events API and Wheel Events. If your device supports it, we can test it.
• Real-Time Visuals: See your Left, Right, Middle, Forward, and Back buttons light up with zero latency.
• Double-Click Detection: Automatically measures the millisecond delay between consecutive clicks to help you identify faulty switches ("double-clicking").
• Scroll Wheel Check: Accurately detects and visualizes vertical scrolling direction (Up/Down).
• Clean Interface: Designed with a distraction-free UI for a seamless testing experience.

🕹️ HOW TO USE

Open the Extension: Click the extension icon in your browser toolbar.

Press any Button: Click your Left, Right, Middle, or Side buttons to see them register instantly.

Test Away: Check for broken switches, verify button mappings, and test your scroll wheel direction right in your browser!
