Your device details
About WhatsMyDevice.net
WhatsMyDevice.net reads the technical details your browser already exposes — things like your browser and operating system, screen and viewport size, timezone, and public IP address — and lays them out in one readable list. There's nothing to install and nothing to configure: load the page and your details appear within a second or two, ready to copy, download, save as an image, or print.
Why check your device and browser information?
Most people end up here for a practical reason rather than out of curiosity. A few common ones:
- Reporting a bug. Support teams almost always ask which browser, version, and operating system you were using when something broke. Copying the details from this page straight into a support ticket is faster than digging through browser menus.
- Web design and development. Designers and developers checking how a layout behaves on their own machine often need their exact viewport size, screen resolution, and device pixel ratio on hand.
- Confirming a VPN or proxy connection. Comparing your public IP address before and after connecting is a quick way to confirm the connection is actually routing your traffic.
- Checking software requirements. Some downloads list minimum requirements in terms of available CPU cores or device memory; this page shows what your browser can see of each.
Understanding your results
Each row in the tool above maps to a specific piece of information your browser makes available:
- Browser
- The browser application and version number, identified from your browser's user agent string.
- OS
- The operating system your device is running, such as Windows, macOS, Linux, Android, or iOS/iPadOS.
- Device
- A best guess at whether you're on a desktop, tablet, or mobile device, based on your user agent and touch support.
- User Agent
- The full, raw identification string your browser sends to every website you visit.
- Screen Resolution
- The full resolution of your physical display, in CSS pixels.
- Viewport Size
- The size of the visible browser window itself, which is usually smaller than your full screen resolution.
- Device Pixel Ratio
- How many physical screen pixels are used to draw one CSS pixel — higher on high-density ("Retina"-style) displays.
- CPU Cores Reported by Browser
- The number of logical processor cores your browser reports being able to use, via
navigator.hardwareConcurrency. - Device Memory
- An approximate amount of device RAM, rounded down by the browser for privacy reasons. Not every browser exposes this.
- Language
- Your browser's preferred display language, taken from its settings.
- Timezone
- The IANA timezone your device is currently set to, such as America/New_York.
- Public IP Address
- The IP address your device is currently browsing from, as seen by a third-party lookup service. Use the "Hide IP" toggle to keep it out of the list, copy, and downloads.
How this tool works
Every value shown above is read directly from your browser using standard, publicly available
web APIs (navigator and window) — nothing is scanned or probed on
your device. The one exception is your public IP address, which your browser requests directly
from a third-party lookup service so the page can display it back to you. None of this information
is sent to or stored on our servers. See the Privacy Policy for the full
details, including the analytics and third-party services this site uses.
