UA Demo

Shows the current navigator.userAgent string, low-entropy User-Agent Client Hints data, and — if you click "Request high-entropy" — the detailed signals available with explicit opt-in.

The navigator.userAgent string below is the reduced default (Chrome 145+). Notice that the OS minor version is frozen, and device model is absent. High-entropy values are only loaded on explicit request.
