Fiddler vs LeakedSource: The Verdict

⚡ Summary:

Fiddler: Fiddler is a free web debugging proxy which logs all HTTP(S) traffic between your computer and the Internet. It allows developers to inspect traffic, set breakpoints, and fiddle with incoming or outgoing data. Fiddler can be used to debug traffic from virtually any application that supports a proxy like web browsers, mobile apps, IoT devices, and more.

LeakedSource: LeakedSource is a website that provided access to data from data breaches and leaks. It allowed users to search for their information to see if it had been compromised or leaked, but charged a fee to remove or protect their data. The service shut down in early 2017 after controversy around its practices.
