How the Keyboard Tester works
Click Start Test, then press every key on your keyboard, one at a time or in any order you like. Each key highlights the instant it registers, and stays marked as tested so you can see your full coverage across the layout.
This is the fastest way to check a new or used keyboard for dead keys, confirm a repair worked, or just make sure nothing is sticking before a big match or a long work session.
Everything happens in your browser — no keystrokes are ever recorded, logged, or sent anywhere.
FAQ
Keyboard Tester FAQ
Keys can fail silently — a switch can wear out, get sticky from spills, or stop registering intermittently under a game's input-heavy conditions. Testing every key confirms your whole board is working before it costs you in a match.
