Hey Product Hunt! 👋 I built KeyTester.io to make a simple question easier to answer: “Is my keyboard registering every key?” Open the site, press your physical keyboard keys, and watch them light up. It’s useful when checking a used keyboard, testing a new build, or investigating an unresponsive key. You can: - Test individual keys and key combinations. - See the last detected key and your tested-key count. - Reset and repeat the test. - Switch between light and dark themes. It’s free, with no installation or account required. The current diagram uses US QWERTY labels. Some operating-system shortcuts may not reach the browser, so an unlit key doesn’t necessarily mean broken hardware.
