Frequently Asked Questions
What is a User Agent string?▼
A User-Agent (UA) string is a text sent by browsers and other HTTP clients to identify themselves to web servers. It typically contains information about the browser, rendering engine, operating system, and device.
Why would I need to parse a User Agent?▼
Parsing UAs is useful for analytics, browser-specific feature detection, device targeting, debugging HTTP requests, and understanding traffic patterns from server logs.
How accurate is the parsing?▼
This tool uses regex-based pattern matching for common browsers and OS patterns. While it handles most standard UAs, some less common or spoofed UAs may not parse correctly.
Can I detect all browsers?▼
This tool supports Chrome, Firefox, Safari, Edge, and Opera. Other browsers may be detected as 'Unknown' but basic info like OS and device type may still be available.
