DeviceHub

Frequently asked questions

Quick answers about how DeviceHub works, privacy, and device permissions. Each tool page also has its own FAQ section.

General

Do I need to download software to test my devices?
No. DeviceHub runs entirely in your browser. Open a tool, grant permission if asked, and test instantly, no installs, extensions, or accounts required.
Is DeviceHub free to use?
Yes. Core hardware diagnostic tools are free to use with no account required and no paywall for standard tests.
Does DeviceHub upload my camera or microphone data?
No. Media streams stay in your browser session. We design every tool to process device input locally whenever the browser APIs allow.
Which browsers are supported?
DeviceHub supports the latest Chrome, Firefox, Safari, and Edge. Some advanced APIs may degrade gracefully on older browsers.
Why is my webcam or microphone blocked?
Browsers require HTTPS and explicit permission for camera and mic access. Check site permissions, close other apps using the device, and retry the tool.
Can I use DeviceHub on mobile?
Yes. Tools are mobile-first. Camera and microphone tests work on modern mobile browsers; keyboard tests are best on devices with physical keys.
