Every key lights as you press it. Hold combos to map ghosting, and catch switches that double-type.
Runs only in this browser. Nothing is recorded, stored or uploaded.
Press start, then press every key once. On a phone, connect a keyboard first.

How to read it
- Key map
- Orange means held now, outlined means it worked at least once, red means it chattered. Keys that never light are the ones to look at.
- Most at once
- The largest number of keys your keyboard reported held at the same moment (its rollover, as far as this test can see).
- Ghosting map
- Hold each combo. Pass means every key in it registered together. A row stuck below the full count is a combo your keyboard blocks.
- Chatter
- A second press of the same key less than 40 ms after it was released. People cannot press that fast; worn or dirty switches can.

Questions
Is anything I type sent anywhere?
No. The page only reads which physical key moved, in this tab. Nothing is stored or uploaded, and the log clears when you leave.
What is ghosting?
Cheaper keyboards wire keys in a grid. Press certain keys together and the grid cannot tell them apart, so a key is dropped (blocked) or one you did not press appears. Gaming and most mechanical boards add diodes or report every key, often sold as N-key rollover.
Why does a key like Fn, Print Screen or a media key never light?
Fn is handled inside the keyboard and is never sent to the computer. Some others are taken by your system before a web page sees them. That is not a fault.
Do shortcuts still work during the test?
Yes. Shortcuts with Ctrl or Cmd plus a letter pass through to your browser. Press Stop to release every other key.
