About Us

DeviceHub is a free collection of browser-based hardware diagnostic tools. Test your webcam, microphone, keyboard, mouse, speakers, headphones, and device details without downloads or accounts.

We built DeviceHub for people who need a fast answer before a meeting, class, stream, or support ticket: does this camera work, is the mic muted, which browser am I on? Each tool runs in your tab using standard web APIs and is designed to be clear on phones and desktops.

Privacy comes first. Camera and microphone streams are processed locally in your browser whenever the platform allows. We do not ask you to install an app or create a login to run core tests.

We care about performance and accessibility: static pages, minimal JavaScript, readable layouts, and structured data so tools are easy to find and use. Explore the full tool catalog, read the FAQ, or contact us if something is unclear.
