A tool for revealing software that runs code on each webpage you visit.
This webpage utilizes a service worker to intercept and display network activity. This page has no assets and does not make any http requests. Thus, any detected network activity is not generated by us.
Browser extensions are the usual culprit, however, there are other forms of software that can inject code onto webpages.
Here's the code for the service worker if you're curious.
