Move your mouse over the popup for 8 seconds and it gives you: - Average polling rate (Hz) - Peak Hz and low 5% threshold - Jitter percentage and stability score - Performance grade (S/A/B/C)
No permissions required, no data collected, all processing happens locally in JS using performance.now() to measure mousemove event intervals.
