About DeviceTester.tech

DeviceTester.tech is an open, high-performance web-based hardware diagnostic and testing suite designed to help PC builders, gamers, remote workers, and mobile consumers verify equipment reliability without installing proprietary software bloatware.

Our Engineering Mission

Too many hardware diagnostics require downloading suspicious .exe files, installing heavy desktop suites, or navigating ad-infested websites that don't function properly on mobile devices. We built DeviceTester.tech to provide instantaneous, lab-grade diagnostics directly through browser-native Web APIs.

Supported Diagnostics

• Mechanical Keyboards: N-Key rollover and key ghosting inspection.
• Gaming Mice: Switch debouncing failure, double-click fault detection, and scroll wheel jitter.
• Displays & Monitors: High-precision display refresh rate (Hz) detection and fullscreen dead/stuck pixel scanning.
