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, send a donation to tjt1980[at]gmail.com via PayPal. Thank you.
