CheckMyDevice

CheckMyDevice is a free, browser-based hardware testing tool that helps users verify supported laptop and desktop hardware before buying, selling, repairing, or handing off a device.

The idea came from noticing that hardware checks are often done manually and without a consistent workflow. 

In many cases, only a few components like the keyboard, camera, and speakers are tested, while other important checks such as the battery, display, network, or sensors can easily be overlooked. Existing browser-based testing tools are also spread across multiple websites, making the process less convenient.

CheckMyDevice brings these browser-accessible hardware tests together into a single guided workflow. It currently includes nine hardware checks covering the keyboard, mouse and trackpad, camera, microphone, speakers, display, battery, network, and sensors. Each module provides immediate feedback, and users receive a simple summary after completing the tests.

Privacy is a core design principle. Everything runs locally in the browser, no account is required, no diagnostic data is uploaded, and results remain on the user's device.

Whether you're buying a second-hand laptop, selling your own device, working in a computer shop, or performing routine hardware checks, CheckMyDevice provides a simple and consistent way to verify supported hardware components.
