Realtime VPN Per-Tab Speed & IP Flag

A zero-overhead real-time VPN speed testing tool based on current tabs, supporting IP flag display, privacy security self-check, and streaming unlock detection. See at a glance which country's server route you're using to browse websites.

🔍 Detailed Description:
Realtime VPN Per-Tab Speed & IP Flag is a lightweight network assistant designed specifically for VPN users. We've redefined speed testing—no longer generic system-wide testing, but focusing on each webpage you're currently browsing.

🚀 Core Highlights:
Innovative "Per-Tab" Real-time Monitoring When you browse with VPN, the extension automatically monitors the access performance of your current tab. By analyzing the default loading content of webpages, we can calculate in real-time the actual speed of your currently connected VPN server when accessing that specific website.

✅ Zero Overhead, Zero Consumption: Default monitoring is entirely based on the webpage's own loading behavior and will never cause any additional burden on your browser performance or bandwidth. You can confidently let it run in the background at all times.

On-Demand Manual "Deep Speed Test" Feeling lag when loading pages? You can manually click the "Deep Speed Test" button.

⚠️ Note: This feature actively initiates network requests to conduct professional-grade stress tests on latency (TTFB), packet loss, and network jitter. It only briefly occupies bandwidth resources when you manually trigger it to obtain the most accurate route quality data.

🇺🇸 Real-time IP & Flag Display Directly displays the IP address identified by the current website and its corresponding country flag in the extension icon and popup, letting you confirm VPN connection status at a glance.

🛡️ Privacy & Security Toolbox

Privacy Detection: One-click check for WebRTC leaks, DNS leaks, and system timezone consistency to prevent real identity exposure.

Streaming Detection: Quickly test whether the current VPN node supports globally popular services like Netflix, Disney+, YouTube Premium, ChatGPT, and more.

📊 Smart History Automatically records access performance data for different websites, helping you compare horizontally to find the most suitable VPN node for you.

⚠️ This extension may show IP (flag) inconsistent with the actual proxy route being used for proxy tools configured with complex rule-based split routing settings. The extension typically only identifies the IP address of the system-level default proxy route.
