Frequently Asked Questions

What is a user agent string?

It is the identification text your browser sends to every website, describing the browser, version, operating system and device so sites can adapt content.

How accurate is the detection?

The parser uses ordered pattern matching for all major browsers (Chrome, Firefox, Safari, Edge, Opera, Samsung Internet), operating systems and bots. UA strings can be spoofed, so treat results as indicative.

What is my user agent?

Press "Use my user agent" to load the exact string this browser is sending right now and see how websites perceive your device.

Does it detect bots?

Yes. Well-known crawlers such as Googlebot, Bingbot and social media fetchers are flagged in the device type result.
