About GadgetCheckup

GadgetCheckup is a collection of free, browser-based tests for everyday devices: microphones, webcams, keyboards, monitors, speakers and mice. It exists because the moment you need a mic test is usually two minutes before a call — and you shouldn't have to install software or upload your voice to a stranger's server to know your gear works.

How it works

Every test uses capabilities built into your browser (the Web Audio API, media devices, keyboard and pointer events). Your audio, video and keystrokes are processed on your own machine and are never transmitted, stored or shared. The site is free to use and supported by ads.
