Test your microphone online with a real-time waveform and volume meter. Record up to 10 seconds and play it back to hear yourself before calls or recordings.
Test your speakers and headphones online. Check left and right channels, sweep frequencies from 20 Hz to 20 kHz, and play tones, noise, or your own audio.
Test your webcam with a live preview, capture photos, and check microphone levels. View camera resolution, FPS, aspect ratio, and lighting.
Test mouse buttons, scroll wheel, click speed (CPS), double-click, and drag. Visual feedback and live counters show if every button works.
Test every key on your keyboard in the browser. Pressed keys glow, tested keys turn green, and a history log catches ghosting and double-typing. Full, TKL, and MacOS layouts.
