About CheckMyMic

CheckMyMic is a set of browser-based device testers built for one moment: when something isn't working and you need to know right now — the call that starts in five minutes, the interview, the stream about to go live.

Our promise

Your test data stays on your device. Your microphone and camera are accessed only to run the test in your browser. We don't record, upload, or store your audio or video. We collect nothing that identifies you. See the privacy policy for the details.

How it works

The browser itself can do what a chatbot never could: read your microphone in real time with the Web Audio API, measure the signal, and tell you plainly whether it's working — or exactly what to fix. One click, no account.

The toolkit today

CheckMyMic now covers your whole kit — microphone, webcam, a combined webcam + mic check, speakers, keyboard, mouse, touch screen, game controller, display refresh rate, dead pixels, battery and connection — each built to the same bar: instant, private, and genuinely helpful. New tools land whenever a real need shows up.

For IT and network administrators

CheckMyMic is a free, general-audience hardware diagnostics utility. The web-filter category that fits it is Information Technology / Computers & Technology. The site serves static pages over HTTPS, requires no account or sign-in, and carries a <meta name="rating" content="general"> declaration.

Microphone and camera access happens only when a visitor starts a test, through the browser's own permission prompt. All processing runs on the visitor's device: audio and video are never recorded on a server, uploaded, or shared, and device streams are released when the test stops or the tab closes. Details are in the privacy policy.

If your organization's filter blocks this domain or lists it under an unrelated category, that is usually a stale newly-registered-domain verdict rather than a content rating. Please submit a recategorization request to your filter vendor citing this page as the site's statement of purpose.
