Frequently asked questions
Does this send any of my information anywhere?
No. Every value here comes from your own browser's built-in JavaScript APIs, like navigator and screen, and is displayed only on your screen. Nothing is transmitted anywhere, by us or anyone else.
Why does my user agent look unusual, or name a different browser?
Modern browsers increasingly send a simplified, generic user agent string for privacy reasons, and some let extensions or settings override it entirely. If it looks off, that's often intentional privacy behavior, not a bug in this tool.
What's the difference between "screen resolution" and "viewport size"?
Screen resolution is your monitor's full resolution. Viewport size is just the visible browser window area showing this page, which is usually smaller once you account for the browser's own UI and any other windows on screen.
