About
Most online mouse testers measure your monitor: they count one movement per frame, so a 1000 Hz mouse reads 60 on a 60 Hz display. inputprobe reads the device events themselves. Every tool publishes its measured error band (from repeated runs on real hardware) and refuses to print a number when the capture can't support one. DPI, polling rate, button bounce, key rollover, eDPI. Free, no accounts, runs entirely in your browser.
