About this tool
Paste any User-Agent string and instantly identify browser family, browser version, operating system, device class, and rendering engine. This tool is useful for analytics debugging, access log inspection, and compatibility issue triage when you need quick human-readable context from raw UA headers.
Frequently Asked Questions
What can I get from a User-Agent string?
You can infer browser family/version, OS, approximate device class and rendering engine for most common modern clients.
Is User-Agent parsing always accurate?
Not always. UA strings can be spoofed or reduced by privacy settings, so results should be treated as best-effort detection.
Can I use this for analytics debugging?
Yes. It is useful when validating traffic reports, bot patterns, or browser compatibility segments.
