Ronin is a free and Open Source Ruby toolkit for security research and development. Ronin contains many different CLI commands and Ruby libraries for a variety of security tasks, such as encoding/decoding data, filter IPs/hosts/URLs, querying ASNs, querying DNS, HTTP, scanning for web vulnerabilities, spidering websites, installing 3rd-party repositories of exploits and/or payloads, running exploits, developing new exploits, managing local databases, fuzzing data, performing recon, and much more.

ronin-recon is a micro-framework and tool for performing reconnaissance. ronin-recon uses multiple workers which process different data types (IP, host, URL, etc) and produce new values. ronin-recon contains built-in recon workers and supports loading additional 3rd-party workers from Ruby files or 3rd-party git repositories. ronin-recon has a unique queue design and uses asynchronous I/O to maximize efficiency. ronin-recon can lookup IPs addresses, nameservers, mailservers, bruteforce sub-domains, port scan IPs, discover services, and spider websites.

ronin-web is a Ruby library that provides common web security commands and additional libraries.

ronin-wordlists is a library and tool for managing wordlists. ronin-wordlists can install and update wordlists, and contains a curated list of popular wordlists and their download URLs.
