How to Parse a User-Agent String
Parsing a UA string is a single paste. Here is what you get back.
Paste the UA string
Copy the user-agent from a log line, a request header or your browser, and paste it in. The parser breaks it into fields immediately.
Read the fields
Check the browser and version, the operating system, and the device type. These answer most "what was the user running" questions in support and debugging.
Frequently asked questions
