How to Test Your Keyboard
This tool checks whether each key on your keyboard sends the right signal to your computer. Broken, stuck, or ghosting keys show up right away. No install needed, no data leaves your browser.
Press any key
Tap a key on your physical keyboard. The matching key on the on-screen layout turns blue while held, then green once released. If nothing happens, that key is not sending a signal.
Check the stats bar
The bar above the keyboard shows the last key pressed, its code, and how many keys you have tested so far. Use this to confirm the exact code each key sends.
Work through every key
Go row by row until the progress bar reaches 100%. Any key that stays white after pressing it may need cleaning or replacement.
