About the Device Information
Support teams, QA engineers, and bug reporters constantly need to know exactly what a user is running: which browser, which OS, what screen size, what locale. A device-information page reads all of it from your browser in one glance - the same data your user agent string and JavaScript environment expose.
View your user agent, platform, screen dimensions, viewport, color depth, CPU cores, connection type, timezone, and language settings. Useful for verifying UA-based routing, reproducing bug reports, or checking what fingerprinting data your browser reveals.
How to use
- Open the page - every value is read automatically.
- Copy your full user agent string if support asked for it.
- Compare viewport vs screen size to verify responsive behavior.
- Check the timezone and locale values your browser sends.
Frequently Asked Questions
What information can a website see about my device? ▾
Your user agent string, platform, screen and viewport size, color depth, CPU cores, device memory, timezone, languages, and connection type. This page shows exactly that set - it is the same data any site can read without permissions.
Why is my viewport size different from my screen size? ▾
Screen size is the physical display; viewport is the area the browser gives the page - smaller because of the browser UI, zoom level, and device pixel ratio. Responsive designs key off the viewport, which is why both numbers matter when debugging layouts.
Is showing this information a privacy risk? ▾
This page reads values locally and displays them to you - nothing is transmitted or logged. The point is transparency: these are the signals your browser hands to every site you visit.
