As answered by people managing SQL Developer and KeyboardTester.click.
KeyboardTester.click's answer:

Users can test keyboard keys, ghosting, N-key rollover, mouse buttons, DPI, screens, microphones, webcams, and speakers without installing software or creating an account. The project is free, open source, multilingual, and designed for quick troubleshooting directly in the browser.

It includes keyboard ghosting, N-key rollover, stuck-key checks, latency tools, mouse tests, display tests, microphone and webcam tests, plus utility tools in one place. It is free, open source, works in modern browsers, supports multiple languages, and does not require downloads or signups.
KeyboardTester.click's answer:
The primary audience is people who need to quickly test computer hardware in the browser: everyday PC users, gamers, mechanical keyboard owners, laptop buyers, repair technicians, IT support teams, schools, remote workers, and anyone troubleshooting keyboard, mouse, screen, mic, webcam, or speaker issues.
KeyboardTester.click's answer:
KeyboardTester.click started as a simple online keyboard tester and grew into a broader free hardware diagnostic suite. The goal is to make common device checks easy for everyone: no downloads, no accounts, no complicated setup. Over time it expanded into mouse, screen, audio, webcam, and utility tools while keeping the same browser-first and privacy-conscious approach.
KeyboardTester.click's answer:
PHP, HTML, CSS, and vanilla JavaScript. The tools use browser APIs such as Keyboard Events, Pointer Events, Web Audio API, MediaDevices/WebRTC, Canvas, and client-side JavaScript libraries where needed.
