Test your physical keyboard by pressing keys and viewing live key name, code, value, and press counts.
Detect how many keys your keyboard can register simultaneously and test for ghosting issues.
Check which keys on your keyboard are working with a clear visual pass/fail grid.
Watch a clean, minimal on-screen keyboard light up in real time as you type or press keys.
Built specifically for gamers, the WASD Tester focuses on the movement cluster - W, A, S, D plus the surrounding Q, E, Shift, Ctrl, and Space keys commonly used for strafing, sprinting, crouching, and jumping. Press each key to see it highlight in real time on a compact diagram, along with press counts so you can spot double-registering keys (a common symptom of a failing switch) or keys that feel unresponsive under rapid, repeated presses the way they would during actual gameplay. It's a faster, more targeted check than running the full keyboard diagnostic when all you care about is your gaming cluster.
The WASD cluster takes the most wear in gaming and is the most likely to develop double-press or unresponsive issues - a focused test is faster than checking every key.
If the count increases without you pressing the key, or increases more than once per press, that can indicate switch bounce or a failing key - a sign to consider cleaning or replacing it.
Yes, the nearby Shift, Ctrl, and Space keys used for sprint/crouch/jump are included alongside WASD.
