User Agent Parser — A user-agent string is the little blurb of text your browser sends to every website to identify itself. It looks like noise, but inside it tells you which browser, which version, which operating system, and which device type made the request. Parsing it is essential for analytics, browser-specific bug reports, and bot detection.
Parsing happens in your browser. Your UA string is not sent anywhere.

ما هو User Agent Parser؟
A user-agent string is the little blurb of text your browser sends to every website to identify itself. It looks like noise, but inside it tells you which browser, which version, which operating system, and which device type made the request. Parsing it is essential for analytics, browser-specific bug reports, and bot detection.
Paste a UA string and get a clean breakdown: browser + version, OS + version, device type (mobile / tablet / desktop / bot), and a bot flag. The "What is my UA" button fills the field with your own browser's UA so you can see it parsed live.
