About keyboardtesterhub
The free, professional keyboard testing tool trusted by gamers, developers, and keyboard enthusiasts worldwide.
Our Mission
We believe everyone deserves to know their keyboard works perfectly—whether you're a competitive gamer counting on split-second reactions, a programmer typing thousands of lines daily, or someone who just bought a new keyboard and wants peace of mind.
keyboardtesterhub provides comprehensive, professional-grade keyboard diagnostics completely free, directly in your browser, with no downloads or installations required.
What You Can Test
Key Registration
Verify every single key on your keyboard registers properly. Visual feedback shows pressed and tested keys in real-time.
N-Key Rollover
Test how many keys your keyboard can register simultaneously. Essential for gamers and power users who need multiple key inputs.
Anti-Ghosting
Check for ghosting issues where pressing certain key combinations causes phantom inputs or missed keypresses.
Response Time
Measure keyboard response latency with our gaming test mode. Lower latency means faster in-game reactions.
Gaming Combos
Test common gaming key combinations like WASD + Shift + Space to ensure your keyboard handles complex inputs.
Mouse Testing
Also test your mouse buttons and scroll wheel. Complete input device verification in one tool.
How It Works
keyboardtesterhub uses your browser's native keyboard event APIs to detect and visualize keypresses in real-time. When you press a key, your browser tells our application which key was pressed, and we display it on the virtual keyboard.
Privacy First
Everything happens locally in your browser. We don't record your keystrokes, send data to servers, or store any information about what you type. The tool only detects which keys are pressed—not what you're typing.
