Client Hints Checker

See which User-Agent Client Hints and fallback browser values are visible in this browser session.

Client hints are browser-controlled. Some high-entropy values may require request headers or browser permission and may not be visible from client-side JavaScript alone.

What this checks

The checker reads navigator.userAgentData when available, then shows low-entropy hints such as brands, platform, and mobile status. It also shows user-agent fallback values.

When the browser allows it, the script asks for a small set of high-entropy values and labels the result clearly.

Limitations

  • Browser policy decides which hints are exposed.
  • Server-requested hints may differ from client-side values.
  • Some browsers do not support navigator.userAgentData.
  • This page does not send hint values to a server.

Reduce exposure

What to do next

Client hints are mostly controlled by browser design and site request policy.

  1. Keep your browser updated to benefit from current user-agent reduction behavior.
  2. Review privacy settings that limit high-entropy hints when available.
  3. Compare with the User-Agent Checker to understand fallback values.
