Keyboard Tests
Test your keyboard online. Check every key for dead or stuck switches and ghosting, then measure your typing speed in WPM. No install, all in your browser.
One key is the giveaway. The spacebar drops every fifth press, or holding W, Shift, and Space together in a game registers only two of the three. Press every key here and each one lights as the board reports it, so you know within a single press whether a switch is sending.
A key that does nothing isn't always a dead switch. It might be a worn contact, but it could also be Sticky Keys, a layout set to the wrong language, or a binding that only breaks inside one app. Quick split: if a key fails here and in every other program, suspect the hardware. If it works here but not in one game, the fault's in software or a binding, and no amount of cleaning will fix it.
Ghosting and rollover are the same story from two ends. A cheap keyboard wires its keys in a shared grid without the diodes that keep presses separate, so some combinations of three keys won't all register at once. N-key rollover means every key registers no matter how many you hold, which is what a ghosting test checks. A few keys never reach this page at all. The keyboard keeps Fn to itself, Windows can claim PrintScreen for its screenshot tool, and a laptop top row in media mode sends volume or brightness instead of F1 to F12. If one of those stays dark, the system took it and the switch is fine.

FAQ
- How do I test my keyboard in the browser?
- Click into the tester, then press every key once. A key that stays dark is either failing or reserved by the system. Don't skip the function row and numpad. Those get missed most often. Open the keyboard tester
- A key does nothing in the test. Is it dead?
- Maybe, but check the easy causes first. If the key is dark here and in a text editor, the switch is probably dead or its solder joint has cracked. If it works here but fails in one game, it's a binding. Sticky Keys can swallow a press, and a mismatched layout makes one key type a different character.
- What is keyboard ghosting?
- Ghosting is when you hold several keys and one stops registering. Cheap keyboards share matrix wiring without diodes, so some three-key combinations won't all register. It bites hardest in games where you're holding movement, sprint, and a weapon key at once. Snap Tap and SOCD muddy this. With either turned on, pressing D cancels A by design, so that pair looks like it ghosts when it doesn't.
- What is N-key rollover and do I need it?
- N-key rollover, or NKRO, means every key registers no matter how many you hold at once. You want NKRO for gaming, where three or four keys are down together. For typing it doesn't matter, since you're rarely pressing more than two at the same time.
- Why does one key type twice when I press it once?
- That's key chatter, and it points to a worn or dirty switch bouncing as it closes. Type a word in any text box and one letter comes out twice. Cleaning the switch or raising the debounce time in your keyboard's software often clears it. A dead switch needs replacing. How to fix a stuck or dead key
- Why does a key not register here even though the keyboard works?
- Some keys never reach the page. Fn stays inside the keyboard, Windows often opens its screenshot tool on PrintScreen, and a laptop top row in media mode sends volume or brightness keys instead. Those blanks are normal. Hold Fn or turn on Fn Lock to test the F keys.
