Camera Tester
Check that your webcam works — see a live preview, switch between cameras and read the actual resolution and frame rate. Nothing is recorded or uploaded; the feed never leaves your device.
How it works
This asks your browser for camera access with getUserMedia, then shows the live stream in a <video> element and reads the track's real settings (resolution and frame rate). If you have more than one camera, a menu lets you switch. The video is displayed only — never captured, saved or sent anywhere — and stops the moment you press Stop or leave the page.
