# Polling Rate Test

> Free online mouse polling rate tester. Measures your mouse's reporting frequency (Hz) in real time — no downloads or installations required. Works with all mice from 125 Hz to 8000 Hz.

## Core Tool

- [Mouse Polling Rate Test](https://pollingratetest.com/): The main interactive tool. Move your mouse on the canvas to measure average Hz, peak Hz, jitter, and stability in real time using the browser's Pointer Events API and high-resolution timestamps.
