The Recon-ng Framework
Recon-ng is a full-featured reconnaissance framework designed with the goal of providing a powerful environment to conduct open source web-based reconnaissance quickly and thoroughly.
Recon-ng has a look and feel similar to the Metasploit Framework, reducing the learning curve for leveraging the framework. However, it is quite different. Recon-ng is not intended to compete with existing frameworks, as it is designed exclusively for web-based open source reconnaissance. If you want to exploit, use the Metasploit Framework. If you want to social engineer, use the Social-Engineer Toolkit. If you want to conduct reconnaissance, use Recon-ng! See the Wiki to get started.
Recon-ng is a completely modular framework and makes it easy for even the newest of Python developers to contribute. See the Development Guide for more information on building and maintaining modules.
Recon-ng is free software. However, large amounts of time and effort go into its continued development. If you are interested in financially supporting the project, you can view and assist in marketing the Pluralsight content, or send a donation to tjt1980[at]gmail.com via PayPal. Thank you.
