This is a pure Javascript tool (browser agnostic) and doesn't need to install any Browser-Extensions.

You can use this tool to hook into XMLHttpRequest (xhr, ajax) requests and you can tamper/modify/replay requests.

Installation

Can be used in console or as a browser-snippet.

1. Just copy the code and add that code as a browser-bookmark (snippet), name it whatever you want (i.e. My Tamper)

2. Right-click > Edit > add the javascript: prefix in front of the code.

Usage

• Open any target website where you want to tamper the ajax-request (like "button-click", form-submission or etc...)
• Click the browser-bookmark to activate the code and you will see the primitive window.

• Make any AJAX request on the target website and you will see the request tampered and filled. Then you can modify & replay it.
