Frequently Asked Questions
What is a user agent string?
A user agent string is a text identifier that your browser sends to every website you visit. It contains information about your browser, operating system, and device.
Websites use this information to deliver optimized content, track browser compatibility, and analyze traffic.
User agent strings follow a specific format but have become increasingly complex over the years due to backward compatibility requirements.
Why are user agent strings so complicated?
User agent strings have grown complex because browsers historically added tokens from other browsers to ensure compatibility with websites that performed browser detection.
For example, Chrome includes Mozilla, Safari, and other identifiers in its user agent string for compatibility reasons.
Our parser cuts through this complexity to give you clean, readable results.
Is my user agent unique to me?
Your user agent is not unique to you personally, but the combination of user agent plus other browser characteristics can contribute to browser fingerprinting.
Many people share the same user agent string if they use the same browser version on the same operating system.
Modern browsers are reducing user agent detail through the User-Agent Client Hints initiative to improve privacy.
Can I parse user agents from my server logs?
Yes. Copy any user agent string from your server access logs and paste it into the parser to identify the browser, OS, and device that made the request.
This is useful for analyzing traffic patterns, debugging browser-specific issues, and identifying bot traffic.
All parsing happens in your browser so your log data is never sent to any server.
