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.

Supporting evidence

Use this User-Agent Client Hints as one browser signal, not a full verdict

Run this subtest before and after one browser/privacy setting change when you need focused evidence. For a combined IP, DNS, WebRTC, IPv6, fingerprint, and User-Agent view, use the Public Exposure Report.

BaselineRun the subtest before changing browser, extension, GPU, font, or privacy settings.
RetestChange one setting, restart the browser if needed, and rerun the same subtest.

How to use the output

Treat results as review signals for this browser/session or public target. Re-test after one change, then use Safe Copy or notes that avoid raw identifiers.
