Open-source hardware diagnostics that test your microphone, camera, screen, keyboard, sensors and network.

APP OVERVIEW

What is d3vices — hardware diagnostics and who is it for?

d3vices is an open-source diagnostics tool for checking the hardware on your device. It tests the microphone, camera, screen, keyboard, sensors and network, so you can confirm what works and what does not. Each test focuses on one component. You can watch a live microphone waveform and play back a short recording, view your webcam and its actual resolution and frame rate, press keys to see them register, and measure network latency, jitter and transfer speeds against a real endpoint.
