Browser environment check

Inspect the environment your browser reports to this page. Useful for diagnosing language, time zone and display differences.

Run the tool

Read language, time zone, display properties and feature support. Run again after changing browser settings.

The check reads browser properties only. It does not upload or store them, request camera or microphone access, or start a WebRTC network connection.

How to use this tool

  1. Read the environment to see browser-reported language, time zone and display properties.
  2. Change settings or resize the window, then run it again to compare.
  3. Use this information for compatibility checks, not as an identity or account-safety guarantee.

Frequently asked questions

Does this collect my browser fingerprint?

It does not upload properties or create or store a unique identifier. It does not run Canvas, audio or font-enumeration fingerprint tests.

Does WebRTC support mean an IP leak?

No. Feature availability and network address exposure are different. This tool does not start a WebRTC connection.

Why are viewport and screen sizes different?

The viewport is the area available to the page. Screen size is what the browser reports for the display. Zoom and display settings can affect both.
