About the Browser Info
A one-page report of what your browser and device expose to websites: user agent, screen and viewport sizes, CPU core count, timezone, GPU string via WebGL, battery status and more. Values update live when you resize the window. Useful for debugging responsive layouts and support tickets.
How to use the Browser Info
- Open the tool โ the table fills immediately, no clicks needed.
- Resize the browser window to watch the viewport row update live.
- Copy any value you need for a bug report or CSS media query.
- Check the GPU row when debugging WebGL or rendering issues.
Browser Info FAQ
Why does the user agent look so strange?
Browsers deliberately mimic each other for compatibility, and some values are being frozen for privacy. Treat the UA string as a hint, not a fact.
What are CPU cores and device memory?
navigator.hardwareConcurrency reports logical cores and deviceMemory reports a rounded RAM figure โ both are intentionally approximate to reduce fingerprinting.
Is any of this information sent anywhere?
No. Everything shown is read from your own browser and rendered on the page. Nothing is transmitted.
