CheckYourDisplay VS HardwareTestingPro

CheckYourDisplay's answer

It puts 53 hardware tests on one site, all running in the browser: screens, speakers, headphones, microphones, webcams, keyboards, mice, touchscreens, pens and game controllers. There's nothing to install and no account to create, and audio and video from your camera and microphone never leave the page.

Every test page also explains what the test can detect, how it works and where its limits are. The Used Laptop Check turns the individual tests into a guided checklist that ends with a report you can copy or print.

HardwareTestingPro's answer:

HardwareTestingPro combines 77+ hardware diagnostic tools into a single browser-based platform - no installs, no sign-ups, and no ads getting in the way. From keyboard and mouse testing to monitor, mic, camera, and gamepad checks, everything runs instantly using your browser's built-in APIs, giving accurate real-time feedback in seconds.

CheckYourDisplay's answer

Many alternatives cover a single device type, or ask you to download an app first. CheckYourDisplay covers display, audio, microphone, camera and input tests in one place, runs in a modern browser on a computer or a phone, and needs no install or sign-up.

It's free, and it's upfront about what a browser can and can't measure, so you know when a result needs a second check.

HardwareTestingPro's answer:

Unlike many hardware testing tools that require downloads or account creation, HardwareTestingPro works entirely in the browser with zero friction. It offers a wider range of tools (77+) in one place, a clean and fast interface, and results you can trust without worrying about privacy or bloatware.

CheckYourDisplay's answer

People checking their own hardware:

• new monitor owners looking for dead pixels or backlight bleed while they can still return it
• buyers of used laptops and phones
• gamers checking refresh rate, mouse polling rate or controller stick drift
• anyone whose microphone, webcam or speakers stop working right before a call

It also suits repair shops, refurbishers and IT teams that need to check devices quickly.

HardwareTestingPro's answer:

Gamers checking peripherals before matches, IT professionals troubleshooting hardware issues, remote workers setting up new equipment, and everyday users who want a quick way to confirm their keyboard, mouse, webcam, or mic is working properly.

HardwareTestingPro's answer:

HardwareTestingPro was built out of frustration with clunky, ad-heavy hardware testing websites that required downloads for simple checks. The goal was to create a fast, free, no-nonsense tool that works instantly for anyone who needs to verify their hardware is functioning correctly.

CheckYourDisplay's answer

The site is built with Astro and Preact and runs on Cloudflare Workers.

The tests use standard browser APIs: Web Audio, MediaDevices (getUserMedia) for the camera and microphone, the Gamepad API, Fullscreen, Pointer Events, Screen Wake Lock, Device Orientation and Motion, Vibration and WebGL.

HardwareTestingPro's answer:

HardwareTestingPro is built using core web technologies - HTML, CSS, and vanilla JavaScript - along with native browser APIs (such as the Web Audio API, MediaDevices API, and Gamepad API) to power the real-time hardware testing tools directly in the browser, without relying on heavy frameworks or backend dependencies.
