User agent parser
Use User agent parser to inspect information represented in a user agent string. Review the steps, check an example, and inspect the result before using it.
User agent parser: inspect information represented in a user agent string
Use User agent parser to inspect information represented in a user agent string. Review a request sample while debugging how a browser or client identifies itself.
How to use User agent parser
Paste a user agent string and review the fields the parser identifies. Compare the result with the context where the string was collected.
Example and practical checks
Use a non-sensitive sample from a test request rather than a full production log. Check the result in the application where you plan to use it.
What to check before copying
A user agent string can be incomplete, reduced, or deliberately changed. Parsed values are signals rather than guaranteed identification of a person or device.
Common questions
Can it identify the visitor personally?
No. A client identification string does not establish a person’s identity or provide a reliable record of their actual device.
