About Test Your Device

Test Your Device is a free collection of browser-based tools that let anyone quickly check whether their hardware is working — microphone, webcam, keyboard, mouse, screen and more — without installing software or creating an account.

We built it because the existing tools were cluttered, slow, and often uploaded your camera or microphone data to a server. Every test here runs entirely on your own device using standard web technology, so your data never leaves your computer.

What makes us different

• Private by design — nothing is uploaded or recorded.
• No download, no signup, no limits — open a page and go.
• Clear fixes — every test includes simple troubleshooting steps.
• Fast and clean — built to load instantly and work on any device.

How it's funded

The site is free and supported by advertising. We keep ads out of the way of the actual tools.
