Why check browser info?

Support teams ask for this when debugging: exact browser version, OS and settings reveal most compatibility issues. The copy button gives you a ready-to-paste report.

Frequently Asked Questions

What is a user agent string?

Your browser's ID card — sent to every website, naming browser, version and OS.

Is my info sent anywhere?

No. This page only displays what your browser already exposes locally.

Why does it say multiple browsers?

User agents include legacy tokens (like 'Mozilla/5.0') for compatibility — the real browser is identifiable within.
