Frequently Asked Questions
What is a user agent string? +
A user agent string is a piece of text that your browser sends to every website you visit. It identifies your browser name and version, operating system, device type, and rendering engine.
How does this user agent parser work? +
It uses pattern matching (regex) to extract browser, OS, device, and engine information from any user agent string. It auto-detects your current browser's UA on page load.
Can I parse a custom user agent string? +
Yes. You can paste any user agent string into the input field and click Parse to analyze it. This is useful for testing or debugging.
What information can be extracted from a user agent? +
Browser name and version, operating system name and version, device type (desktop, mobile, or tablet), and the rendering engine (Blink, Gecko, WebKit, etc.).
Is my user agent string private? +
Your user agent string is not private -- every website you visit can read it. However, this tool processes everything locally in your browser and sends nothing to any server.
