GabyZodda is a free hardware testing platform with 32 browser-based diagnostic tools. Test your keyboard, mouse, webcam, microphone, speakers, display, CPU, GPU, and more directly in your browser with no downloads required.

Are the hardware testing tools really free?

Yes, all 32 tools on GabyZodda are completely free. There is no subscription, no signup, and no hidden costs.

Do I need to install anything to use these tools?

No. All GabyZodda tools run entirely in your web browser using modern Web APIs. No software installation, no plugins, and no downloads are needed.

Which browsers are supported?

GabyZodda tools work best on Google Chrome, Microsoft Edge, and Mozilla Firefox. Safari has limited support for some browser APIs. We recommend a Chromium-based browser for best results.

Is my hardware data private and secure?

Yes. All hardware tests run locally in your browser. No camera footage, microphone audio, keyboard inputs, or system data is ever sent to our servers. Your data stays on your device.

How do I test if my keyboard is working correctly?

Use our free Keyboard Tester tool. Click the test zone, press any key, and it lights up on screen. This lets you identify stuck, non-responsive, or double-firing keys.

Can I test my webcam without installing software?

Yes. Our Webcam Test tool lets you preview your camera live in the browser, take snapshots, and check resolution and FPS without downloading any software.

How do I check my mouse polling rate?

Use our Mouse Polling Rate tool. Move your mouse over the test zone and the tool measures how many position reports per second your mouse sends (Hz). Standard mice: 125Hz; gaming mice: 500-1000Hz.

What is a dead pixel test?

Our Dead Pixel Test displays full-screen solid colors on your monitor. Dead pixels appear as dots that do not change color, helping you identify stuck or dead pixels on your display.

Can I test my microphone online without software?

Yes. The Microphone Test tool shows a live waveform and volume bars directly in your browser. Grant microphone permission when prompted, then speak to verify your mic is working.
