Device & Peripheral Tests

The hardware you touch every day — mic, keyboard, mouse, speakers, webcam, controller. Six quick checks to confirm they're all doing their job before a call, a stream, or a game.

This is usually the first place people land after a fresh OS install, a driver update, or just before something important — a job interview, a livestream, a ranked match. Each test below opens straight into the tool, reads the real hardware signal through your browser, and shows you exactly what's working and what isn't.

None of these need an account or a download. Mic Test and Webcam Test are the two most people reach for right before a call, while Keyboard Test and Mouse Test tend to get used after buying something new or troubleshooting a hardware complaint. Run the one you need, or work through all six as a quick pre-flight check.

Mic Test

See a live waveform to confirm your microphone is picking up sound.

Keyboard Test

Press every key and instantly spot any that aren't registering.

Mouse Test

Check every button, the scroll wheel, and your polling rate.

Sound Test

Confirm your left and right speaker channels both work.

Webcam Test

Preview your camera feed and check resolution and frame rate.

Controller Test

Test every button, stick, and trigger on your gamepad.

Frequently asked questions

Which test should I run first if my computer feels off?

Start with whatever you were actually trying to do — Mic Test before a call, Webcam Test before a video interview. Running all six only makes sense right after a fresh setup or a driver update, when several things could plausibly be affected at once.

Do these tests work on a laptop's built-in hardware too?

Yes. Every test reads whatever microphone, camera, keyboard, or mouse your browser currently has access to, whether that's built into a laptop or plugged in externally.

Is any of this hardware testing dependent on Windows or Mac specifically?

No, all six tools run the same way in any modern browser on Windows, macOS, Linux, or ChromeOS. A few individual test pages include OS-specific settings tips, since permission menus differ between systems even though the test itself doesn't.
