GabyZodda offers 32 free hardware diagnostic tools for keyboard, mouse, webcam, speakers, display, CPU and GPU — no downloads, no account needed. Results in seconds.
GabyZodda provides 32 free hardware diagnostic tools that run directly in your web browser. Whether you are a PC gamer troubleshooting your peripherals, a remote worker verifying your webcam and microphone before a meeting, or a technician doing quick diagnostics on a client machine, GabyZodda gives you accurate, instant results with zero friction.
All tools use modern browser Web APIs — WebAudio, WebRTC, WebGL, Gamepad API, Battery API, Device Orientation API, and more — to communicate directly with your hardware. This means no software installation, no administrator privileges, and no security risk. The tests are as accurate as what your operating system reports to the browser.
From keyboard tester and mouse polling rate checker to dead pixel test and microphone test, every tool is designed to be simple, fast, and reliable. Each tool launches within the same page — no redirects, no ads before the tool, no signup walls.
GabyZodda is completely free for everyone. No premium tier, no tool limits, no watermarks. Our mission is to make hardware troubleshooting accessible to every user regardless of technical skill level.

No. All tools run entirely in your browser using modern Web APIs. No software installation, no browser extensions, no plugins needed. Works on any modern browser.
Google Chrome, Microsoft Edge, and Mozilla Firefox give the best results. Safari has limited support for some APIs (WebRTC, Gamepad). Chromium-based browsers are recommended for the full 32-tool experience.
Completely. All hardware tests run 100% locally in your browser. No camera footage, microphone audio, keyboard input, or system data is ever transmitted to our servers. Your data never leaves your device.
Use our Keyboard Tester — click the test zone, press any key, and it lights up on screen in real time. This lets you identify stuck keys, non-responsive keys, or double-firing keys on any keyboard.
Our Mouse Polling Rate tool measures how many position reports per second your mouse sends (Hz). Move the mouse inside the test zone and the live reading appears instantly. Standard mice = 125Hz, gaming mice = 500–1000Hz+.
Yes. Our Webcam Test tool shows a live preview, lets you take snapshots, and checks resolution and FPS — all in the browser without any software.
Our Dead Pixel Test displays full-screen solid colors (black, white, red, green, blue). Dead pixels appear as dots that stay the wrong color, making them easy to spot. Works on any monitor or laptop screen.
Yes. The Microphone Test tool shows a live waveform and volume meter in your browser. Grant mic permission when prompted, then speak — you'll see immediately if your microphone is working.
