About This Launch
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 (WPM) test, plus mouse click, jitter and scroll-wheel tests.
Why I Built This
We wanted a fast, private way to check whether a keyboard or mouse is faulty without installing sketchy software, so we built a free browser tool anyone can use in seconds.
