Free checks, right in your browser

IsItOK is a collection of free online checks for your browser, screen, camera, microphone, speakers and input devices. Every test runs directly in this browser — no account, no installation and no upload.

Tests that need a device, such as the camera or microphone, ask for permission only when you start them. Measurements are processed on your device and are not sent anywhere. Results stay on the page until you leave or copy them yourself.
