What does the parser detect?

Browser name and version, rendering engine, operating system with version, device model and vendor, and CPU architecture — powered by ua-parser-js.

Can I test my own browser?

Yes. Click 'Use my browser's UA' to paste in the current navigator.userAgent value and parse it instantly.

Is UA detection reliable?

UA strings can be spoofed and are not always accurate, but ua-parser-js covers thousands of known patterns and is battle-tested for analytics.
