What is KeyboardAnalyzer?
KeyboardAnalyzer is a free online keyboard tester that runs entirely in your browser, with no download or sign-up. Press any key to see its live status and key codes on Windows, Mac and laptop layouts. It includes ghosting and NKRO tests, input latency and polling-rate tests, key chatter detection, a spacebar test and a typing speed test, plus mouse tools for clicks, jitter, scroll and polling.
What it solves
- Hard to tell if a key is dead, ghosting, or chattering
- Installed testers are awkward, and laptop layouts differ
- Mouse click, scroll, and polling issues need a check too
How it works
- Press any key in the browser to see status and key codes
- Run ghosting, NKRO, latency, chatter, and WPM tests
- Test mouse CPS, double-click, jitter, scroll, and polling
