Is there a non-installable version of Fiddler, or equivalent? [closed]

Answer 1

In fact, Fiddler Classic does not need to be installed:

• Download Fiddler Classic setup (ie. FiddlerSetup.exe)
• Open it with your Archive Manager (ie. 7-Zip)
• Open $PLUGINSDIR folder
• Open the contained FiddlerSetup.exe (yes again) in your Archive Manager

• Extract the files in a folder
• Run Fiddler.exe

For Fiddler Everywhere, it is almost the same

• Download Fiddler Everywhere (ie. Fiddler Everywhere 1.0.1.exe)
• Open it with your Archive Manager (ie. 7-Zip)
• Open $PLUGINSDIR folder
• Open the contained app-64.7z file in your Archive Manager

• Extract the files in a folder
• Run Fiddler Everywhere.exe
