Identifying Technologies with BuiltWith and WhatWeb

In the domain of web development and penetration testing, identifying the technologies used by a website can provide a wealth of information. In this guide, we will explore how to use the BuiltWith extension and the whatweb tool for this purpose.

Using the whatweb Tool

whatweb is a lightweight, flexible tool that identifies the technologies powering a website, including the CMS, scripts, and server software. It is not a browser extension but a standalone tool that can be run from the command line.

Options

• -v: Enables verbose mode, providing detailed information about the identified technologies.

• -a: Controls the aggression level. It ranges from 0 (least aggressive) to 4 (most aggressive).

• --color: Use this option to enable colored output.

• -p: Specifies a proxy server to use during the scan.

Usage

To use whatweb, you can utilize the following command with the -v option for verbose output:

whatweb --color -v www.example.com
