<h2>Fiddler or Fiddler Everywhere</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>I am planning to use both Fiddler and Fiddler Everywhere alternatively. My first preference is Fiddler Everywhere, because of its simplicity and intuitiveness. If the feature is not available in Fiddler Everywhere, then I switch it to Fiddler.</p>
