Frequently Asked Questions
Is this tool free?
Yes! User Agent Parser is 100% free with no registration required.
Is the detection 100% accurate?
User agent strings can be spoofed or customized, so detection reflects what the browser reports, not an absolute guarantee.
Can it detect the exact device model?
It detects broad categories like Mobile or Desktop and general OS, not specific device models.
Is my data sent anywhere?
No, parsing happens entirely in your browser using JavaScript.
