Measure the frame rate delivered to your browser after granting camera permission. Results can vary with light, USB bandwidth, drivers, and browser processing.
Accesses your webcam and estimates the frame-update rate delivered to the browser. Shows live FPS, average FPS, and device info.
A webcam's stated frame rate is the maximum under ideal conditions. The stream delivered to a browser depends on lighting, USB bandwidth, CPU availability, drivers, and camera firmware. This tool estimates frame-update rate by watching for changes in a small sample region, so a mostly static scene can undercount frames.
Use the result as a practical browser-stream comparison when diagnosing choppy video or checking changes in lighting, USB ports, and camera settings. It is not a sensor-level camera benchmark.
