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-exploits is a Ruby micro-framework for writing and running exploits. ronin-exploits allows one to write exploits as plain old Ruby classes. ronin-exploits can be distributed as Ruby files or as git repositories that can be installed using ronin-reps. It's like a simpler version of Metasploit.

ronin-app is a small web application that is meant to be ran locally by the user. It provides a web interface to ronin-support, ronin-repos, ronin-db, ronin-payloads, ronin-exploits, as well as automating ronin-nmap, ronin-masscan, ronin-web-spider, ronin-recon, and ronin-vulns.
