About this tool
Support agents ask what browser you're running because the answer tells them which bugs are likely and which fixes will work. This tool reads that information from your browser and shows it plainly: name, version, operating system, device type, and the full user-agent string you can copy into a ticket. Detection uses User-Agent Client Hints where your browser supports them (more reliable) and falls back to parsing the classic user-agent string otherwise.
Frequently asked questions
Why can't I see the exact version on Safari or iOS?
Apple intentionally pins Safari's user agent to reduce fingerprinting. You'll see a general version but not a full build number. On iOS, all browsers (even Chrome and Firefox) use Safari's engine underneath, so reported info reflects that.
What is a user agent?
The User-Agent is a string your browser sends with every HTTP request, identifying itself. It has accumulated historical artifacts — modern Chrome still claims to be "Mozilla/5.0" for compatibility with ancient sites. Client Hints are the more reliable modern replacement.
Is detection always accurate?
Mostly. Extensions can spoof the user agent, and some privacy-focused browsers send a generic string to reduce tracking. Browser sniffing is also a losing game in general — if your code needs to know whether a feature exists, prefer direct feature detection over UA strings.
