MousePollingRateTest is a free browser-based testing suite for gaming mice, keyboards, and PC peripherals.

The main tool measures mouse polling rate / mouse Hz from 125Hz to 8000Hz, including average rate, peak rate, low 5 percent, jitter, stability, dropouts, and input timing. It helps gamers, hardware reviewers, and PC users check whether their mouse, USB port, wireless dongle, firmware, or driver settings are performing as expected.

The site also includes click speed, reaction time, double-click/chatter detection, mouse button testing, scroll wheel testing, mouse accuracy testing, keyboard polling rate testing, spacebar speed testing, and key press testing.

Everything runs directly in the browser. No download, account, extension, or setup is required. It is useful as a quick online alternative to desktop mouse testing software when users want to compare polling rates, diagnose unstable input, or verify peripheral behavior before changing hardware or manufacturer settings.
