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.
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.
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.
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.

Mercari.jp is the second most popular. Don't get this confused with mercari.com, because while it is the same company, the listings aren't transferable. Mercari is basically like facebook marketplace, first come first serve. They also hate proxy services, so its harder for people not in japan to buy from them. I'll explain more in the proxy section.
