What this tool is for
Your user agent string, shown in full and broken into its parts. The string is what servers use to guess your browser, and reading it is the first step when debugging a bug that appears for one client and not another.
How to use it
- Read your user agent string at the top of the page.
- Check the parsed breakdown: browser, engine, version, platform, device type.
- Copy the raw string for a bug report or a test configuration.
Frequently asked questions
Why does the string say so little on newer browsers?
Because it is being frozen deliberately: minor version numbers and platform detail were a fingerprinting surface. Chromium browsers now expose that information through Client Hints, which the server has to request.
