Netmonitor Chrome Extension: Real-Time Network IO Tracking

'Netmonitor' is a Chrome extension that highlights and tracks background network I/O activities taking place on web pages. Even after the initial loading, webpages continuously interact with the network via JavaScript, often without the user's knowledge. These activities include tracking user actions, transmitting data, or loading resources. Netmonitor presents a count of these ongoing requests in an easy-to-read indicator, updated in real time for each tab.

Extension summary

The "loading" icon for tabs in browsers only spins at first when the page is loaded. But even after that, web pages can do network IO via JavaScript in background without the user knowing. This extension highlights such network activity and shows a count of requests done till now by the page in a small indicator. It's updated in real-time for each tab.

A lot of web pages use background network requests for tracking user actions and sending data to remote servers, lazily loading heavy assets etc., and all that goes unnoticed by the user. Ideally, the browser's "loading icon" should spin for those requests as well.

Doesn't do anything useful. Just shows an icon with a number on it. Clicking on it doesn't do anything.
