Why Use [SITE NAME]?
Every tool on this site runs entirely inside your web browser. There is nothing to download, install, or sign up for. Whether you're troubleshooting a sticky controller, verifying a new gaming mouse, or comparing monitors before a purchase, you can run the test in seconds.
Built for Accuracy
Our tools use the latest browser APIs â the Gamepad API, Pointer Events, requestAnimationFrame timing â to deliver readings that closely match dedicated hardware utilities. We document the limitations of each tool honestly so you know exactly what the numbers mean.
