About TestKey
A quick, honest check for physical keyboards, right in your browser.
What TestKey does
TestKey helps you find out whether every key on a keyboard works, without installing anything. It is built for people who just bought or cleaned a keyboard, who notice missing or doubled letters, who sell or buy used equipment, and for repair work.
- Keyboard test for Windows and Mac layouts, with a downloadable report, result image and share link.
- Ghosting and rollover test for key combinations.
- Chatter test for keys that type twice.
- Numpad test and keycode tester.
How we think about results
TestKey reports only what the browser actually receives and says clearly what it cannot see. It does not label a key as broken, does not estimate hardware latency and does not certify rollover. The methodology page lists every rule.
Sponsor TestKey
Sponsored placements are not open yet. TestKey will keep the test itself free of ads that move or cover the keyboard. For partnership questions, use the contact page.
