User-Agent Analyzer Guide
1
Open the page and your device User-Agent is filled in and parsed automatically — nothing to do
2
Want to parse another UA? Paste the string into the box and click "Analyze User-Agent"
3
Check the browser, OS and device info in the result cards, or click "Copy my UA" to save it
🔎What it can detect
- Browser: name and version, e.g. Chrome, Safari, Edge, Firefox
- OS and version: Windows, macOS, iOS, Android, Linux and more
- Device type, rendering engine (Blink/WebKit/Gecko) and CPU architecture
💡Tips
- A UA can be spoofed by the browser or extensions, so treat the result as a reference
- Some modern browsers trim their UA, so a few fields may show as unknown
- When debugging compatibility or filing bugs, sharing the UA helps others reproduce it
The User-Agent is an identifier string every browser sends with each request, letting servers decide what kind of page to return. This tool uses UAParser to turn that string into clear, readable browser, OS and device info.
🔒 Runs entirely locally in your browser, the UA is never uploaded; auto-detects your device, parses any UA and copies in one click — no install, no signup.
