Desktop keyboards work best. Use your physical keyboard — on-screen mobile keyboards are not supported.
Keys work? Measure your speed
A keyboard checker confirms input. A typing test shows real WPM, accuracy, and weak keys from your latest run.

- • Pick a keyboard layout that matches your operating system, then press every key once.
- • Include modifiers, the function row, arrows, and numpad if you have one.
- • If a key never turns green, try another browser tab or USB port before replacing hardware.
- • For typing benchmarks, use a wired connection when possible — Bluetooth can add input lag.
