What This Tool Checks

Some online services estimate region from IP address, browser language, timezone, installed fonts, and similar signals. This tool reports those signals in the current browser so you can see what a region check might observe.

Each signal is weighted by how commonly it is used as a region hint. The result is a score from 0–100%. The tool does not circumvent access controls or change how a third-party service admits traffic.

How to Use This Tool

Open this page in the browsing environment you want to inspect. The tool runs the listed checks automatically. IP geolocation contacts ipapi.co; other checks run in this tab, and network reachability probes a few public sites.

Each result reports the observed value for that check. This tool does not change browser settings or how another service admits traffic.

Understanding the Signals

What makes IP geolocation the most critical signal?

Services often determine country from the public IP address. This check queries ipapi.co. If that lookup reports China, a service that restricts that region will typically deny access. Changing network path is outside this tool.

Why check for super-app JSAPI?

A WeChat, Alipay, Douyin, or similar webview injects bridge objects (WeixinJSBridge, AlipayJSBridge, and others). This check reports whether those objects are present.

What does the network reachability test do?

The tool attempts to reach Google, YouTube, X (Twitter), and Facebook in parallel with 3-second timeouts. The result lists how many of those hosts responded; it does not infer a network path or recommend a change.

Reading the report

What does the score mean?

The score is a weighted mix of the checks on this page. A higher score means more of the listed signals currently look China-associated. It is a local report, not a verdict from any third-party service.

Does this tool change access to other sites?

No. It does not alter your network path, browser settings, or how another service admits traffic. It only displays what this tab can observe.

Why is IP listed separately?

The IP check queries ipapi.co and shows the country that lookup returns. Other checks run in this tab. Unreachable public sites are listed as reachability results, not as a recommended network change.
