"What browser and OS are you using?" is one of the first troubleshooting questions — pasting an exact report is faster than typing from memory. Use our free Device & Browser Info checker to view and copy your details.
Bug Reports and Support
When reporting a bug to a developer or support team, include browser name, version, OS, screen resolution, and viewport size. A copied report is more accurate than guessing.
Responsive Design Testing
Quickly verify your viewport size and device pixel ratio when testing responsive layouts — especially on high-DPI displays where physical resolution and CSS pixels differ.
Nothing Hidden — Just Displayed
This tool only reads information your browser already exposes to any website through standard APIs. It doesn't collect anything unusual — it shows you what sites can already see.
Frequently Asked Questions
Why does this matter for reporting a bug?
Developers and support teams often need to know your exact browser, OS, and screen details to reproduce and fix an issue — providing this upfront saves back-and-forth troubleshooting questions.
Is this tool collecting information I wouldn't normally share with websites?
No — every website you visit can already see this same browser/device information through standard web APIs; this tool just displays it back to you in a readable format rather than using it silently.
Why might my screen resolution look different from what I expect?
Device pixel ratio (common on high-DPI/Retina displays) means the reported resolution can differ from your monitor's physical pixel count — the viewport size is what's actually relevant for most web design purposes.
Does this tool detect my exact location?
No — it reports device/browser technical details (screen, OS, browser version) and your browser's reported timezone setting, not your geographic location.
