How the keyboard test works

Events are captured locally in the browser; nothing is sent to a server.

We highlight keys using the event code when available, then fall back to the character you pressed.

Tips for accurate results

  • Disable browser shortcuts if they interfere with specific keys.
  • Try both left and right modifier keys to confirm they register separately.
  • Use the clear button between tests to reset the grid.

Privacy-friendly diagnostics

All detection runs in your browser so you can safely test workstations, laptops, or external keyboards offline.

The virtual layout scales on mobile, tablet, and desktop for quick checks anywhere.
