User-Agent String
What is a User-Agent?
A User-Agent is a string of text that your web browser sends to every website you visit. It acts as an identifier, telling the web server what operating system you are using (e.g., Windows, macOS, iOS, Android), which browser you are running (e.g., Chrome, Safari, Firefox), and what type of device you are on (desktop, tablet, or mobile).
Web developers frequently parse these strings in their backend analytics or frontend logic to serve device-specific layouts or track usage statistics. This parser breaks down complex, messy User-Agent strings into clean, structured data categories instantly.
