Keyboard Tests
Check every key, find ghosting and rollover limits, measure key timing and count your spacebar speed.
Keyboard tests

Find dead, stuck and double-typing keys on any keyboard.
Keyboard Latency Test
Find the polling steps your keyboard reports in, plus press time, tap speed and timing jitter.
Keyboard Ghosting Test
Hold gaming and typing combos and see exactly which keys your keyboard blocks, with a result for each one.
Keyboard Sound Test
Measure how loud each key is with your mic, find rattling stabilizers and compare switches.
Numpad Test

Mac Keyboard Test
Test every key on a MacBook or Magic Keyboard, including the F keys, Command and Option.
Laptop Keyboard Test

Speed tests
Which keyboard test to use
Start with the keyboard tester. It lights every key as you press it, so dead keys, keys that type twice and keys that stick show up in a minute. Laptop owners can switch to the laptop layout or open the laptop keyboard tester, and the mac keyboard test has a Mac layout with the Command and Option keys in the right places. A separate numpad test checks the number pad, Num Lock and your 10 key speed.
Gamers have two more checks. The anti ghosting test shows which key combinations your keyboard blocks when several keys are held at once, and the keyboard latency test measures press timing and how evenly your key presses arrive.
Speed and sound
The spacebar counter counts how fast you can tap a single key, the spacebar clicker turns those presses into an idle game, and the keyboard sound test uses your microphone to measure how loud each keystroke is, which helps track down a rattling stabilizer.
When keys stop working
If a test shows keys that never light up, the keyboard not working guide walks through cables, receivers, Bluetooth, drivers and settings in order. For laptops, the laptop keyboard not working guide covers Fn lock, Num Lock, spills and brand specific fixes.
