I built 3 practical online testing tools to help you out

Hi DEV Community! 👋
As a developer who loves building things, I often find myself needing to test hardware or network metrics. However, many existing tools are either cluttered with ads or have outdated UIs. So, I decided to build three clean, lightweight, and completely free online testing tools using modern web technologies.

I’m sharing them today and hope you find them useful:

1. ⚡ Reaction Time Test What it does: Measures your visual reaction time in milliseconds. Perfect for FPS players warming up or checking your daily mental focus. Highlight: Minimalist UI with zero ads. All tests run locally in your browser, ensuring complete privacy. Try it here: https://reactiontimetest.fun/
2. 🖱️ Click Speed Test (CPS Test) What it does: Measures your Clicks Per Second (CPS). Supports multiple timer modes (1s, 5s, 10s, etc.), ideal for gamers or testing mouse switch durability. Highlight: Highly responsive and tracks your personal best stats accurately. Try it here: https://click-speed-test.net/
3. 🎮 Gamepad Tester What it does: Test your controller directly in the browser. Check all buttons, analog sticks, triggers, and even diagnose "stick drift" issues. Highlight: Built with the browser's Gamepad API. Plug and play with no drivers or software downloads required. Try it here: https://checkgamepad.com/
