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-payloads is a Ruby micro-framework for writing and running exploit payloads. ronin-payloads allows one to write payloads as plain old Ruby classes. ronin-payloads can be distributed as Ruby files or in git repositories that can be installed with ronin-repos. It's like `msfvenom` but simpler and more modular.
