Put a click speed test on any website.

The widget is deliberately boring. It is a single iframe pointed at cpstoolhub.com, so the code in your page stays minimal — no script tags, no style tags, no network requests of your own, and no third-party trackers. Inside the iframe, the tester counts pointer and key events in your visitor's browser and shows the result; nothing is stored, and no request leaves the page except the initial one that loads the widget.

Because the measurement runs entirely in the browser, the widget works on any site — blog posts, documentation, tournament pages, school projects — without touching your server or your cookie banner. If your framework has a safe-iframe or sandbox option, the widget works there too: it needs only allow-scripts allow-same-origin in the worst case, and plain iframes work fine everywhere else.
