Why test hardware online?
Testing hardware online is useful in many situations. After buying a new PC or laptop you can verify within minutes that every component works. Before an important video call you make sure your microphone and camera are ready. When something goes wrong, targeted diagnostics help you find faulty keys, stick drift or dead pixels. And when buying a used monitor, controller or notebook you can quickly check on the spot that everything works — with no extra software.
How the hardware test works
All tests run entirely locally in your browser. No download and no installation are required — simply open the relevant page and start. For microphone and camera tests the browser asks for your permission once; all audio, video and input data stays on your device and is neither stored nor sent to us. That makes the hardware test not only fast and free but also privacy-friendly.
