useforfreeTest your hardware without installing anything
Before an important video call, use the Mic and Camera Test to see your webcam live, watch your microphone level and record a short clip to hear how you sound. Buying a new or second-hand monitor, laptop or phone? The Dead & Stuck Pixel Test fills the screen with solid colours so any faulty pixels stand out, and shows your screen's resolution, refresh rate and colour range. Both tools run entirely on your device: nothing is recorded or uploaded. Want to test yourself instead of your hardware? Try the games.
