A Chrome extension which shows background network activity of web pages after they are loaded.
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, but since it doesn't, I wrote this extension.
Web page constantly making requests even after page load:
note the hexagonal red icon and the request count
simple network icon with request count
