Open Source Ruby Frameworks

Metasploit Framework is a comprehensive penetration-testing and exploit development platform that streamlines the process of discovering, validating, and demonstrating vulnerabilities. It provides a modular architecture—payloads, encoders, exploits, auxiliaries, and post-exploitation modules—so security professionals can piece together complex attack chains or test defensive controls in realistic ways. Built-in features include an exploit database, network scanners, credential harvesters, and frameworks to craft reliable payload delivery while handling target nuances like mitigation bypasses and platform differences. Beyond raw exploitation, the framework includes post-exploitation tooling for lateral movement, persistence, data exfiltration simulations, and evidence collection, enabling red teams to exercise detection and incident response workflows.

Development of this library has been moved to https://github.com/kordamp/json-lib/ Json-lib is a java library for transforming beans, maps, collections, java arrays and XML to JSON and back again to beans and DynaBeans. It is based on the work by Douglas Crockford in http://www.json.org/java.

Rome is a tool that simplifies the management of prebuilt frameworks for CocoaPods. It allows developers to cache and reuse binary frameworks, reducing build times and improving CI workflows.

ZK is an open-source Java framework for building modern web and mobile applications. It enables developers to create rich, interactive UIs using only Java — no JavaScript required. With 200+ Ajax-powered components, event-driven architecture, and support for popular technologies like Spring, Java EE, and JSP/JSF, ZK makes it simple to deliver powerful and user-friendly web applications.

Capybara is a Ruby acceptance testing framework that simulates how a real user would interact with a web application. It allows developers to write tests that drive browsers, checking for expected content, links, buttons, and form interactions. Capybara integrates with drivers like Selenium, Rack::Test, and headless browsers such as Cuprite or WebKit, letting tests run in real browsers or lightweight simulation environments. Its DSL emphasizes natural language-like syntax, such as visit, click_button, and fill_in, which makes tests readable and expressive. Capybara also handles asynchronous JavaScript and dynamic content, waiting for elements to appear or actions to complete before assertions run. By bridging test suites with actual browser behavior, Capybara helps ensure that web apps behave correctly from a user’s perspective.

RubyGems is a package management framework for Ruby. A package (also known as a library) contains a set of functionality that can be invoked by a Ruby program, such as reading and parsing an XML file. We call these packages "gems" and RubyGems is a tool to install, create, manage and load these packages in your Ruby environment. RubyGems is also a client for RubyGems.org, a public repository of Gems that allows you to publish a Gem that can be shared and used by other developers. See our guide on publishing a Gem.

Brutos is an easy and powerful mvc controller configurable for annotation, programming and XML with support for Inversion of Control and Dependency Injection. Compatible with JSF, Velocity, DisplayTag, Spring, PicoContainer, ...

The FreeMIS project is an Open Source, web based, Management Information System for high schools. It has recently been ported to the new Ruby on Rails web development framework. Initially the development will focus on the requirements of UK schools.

This project aims to create a portal framework using the Ruby on Rails web framework. Users will be able to define his/her own page layouts and add portlets to the pages after done defining the layouts.

A drop-in framework for adding tagging (folksonomy) capabilities to existing applications

3D render engine cross platform written from scratch using c++11 standard features. With the approach to create a high scalable, flexible 3D engine with full modding support. Using flexible configs to include common technologies without the lack of massive extension coding

Blueprint CSS is a CSS framework aimed at accelerating layout and typographic design by providing robust base styles, grid systems, and reusable UI components. It combines normalized defaults with helpful utilities—such as column layouts, form styling, and typography helpers—so developers can build responsive sites with less repetitive CSS. Because it’s designed as a structural foundation rather than a themed UI kit, it’s easy to layer branding and custom design on top without fighting the base styles. The framework includes mixins, modifier classes, and responsive breakpoints so layouts adapt fluidly across screen sizes. By starting with a consistent baseline, Blueprint CSS reduces cross-browser quirks and gives designers confidence in spacing, proportion, and element alignment. Teams often use it as the “CSS backbone” of internal tools, web products, or component libraries.

Breeze is a build and test automation framework for software developers. It is written in Ruby and can be extended to include tasks that interact with other tools such as source code repositories, compilers, test frameworks, and installers.

Bricklayer is a Ruby web application framework that uses a component architecture very loosely based on that of perl's HTML::Mason. To see the proof of concept for Bricklayer, check out the Liber RDF Portal project.

A set of tools and utilities that allow development teams to practice code generation techniques in a scalable and extensible manner. This is based on the style of code generation found in Ruby on Rails.

Compass is a stylesheet authoring framework built on top of Sass that provides a rich set of mixins, functions, and helpers for writing maintainable CSS. It offers abstractions for vendor prefixes, cross-browser compatibility fixes, and reusable UI patterns like grids, buttons, and typography helpers. With Compass, developers can write cleaner Sass code that compiles into consistent CSS across browsers without hand-coding workarounds. The framework also includes a command-line tool for compiling Sass, managing sprite sheets, and integrating with build workflows. It was widely adopted in the era before modern CSS standards caught up with mixins and variables, helping developers speed up styling while reducing redundancy. While less dominant today, Compass remains an important historical tool that influenced the evolution of Sass and frontend best practices.

Hanami is a modern Ruby web framework that aims to be lightweight, fast, and modular, in contrast to the monolithic design of Rails. It emphasizes separation of concerns, encouraging developers to structure applications into clear layers of controllers, views, entities, and repositories. Each component—like the router, model layer, or view rendering engine—can be used independently, which gives developers flexibility to build lean applications. Hanami promotes immutability, plain old Ruby objects, and minimized global state, which makes codebases more maintainable and testable. It supports multi-application setups within the same project, making it well-suited for larger service-oriented architectures. The framework is designed to provide Rails-like productivity while encouraging more explicit architecture and performance-conscious choices.

Laika analyzes and reports on the interoperability capabilities of EHR systems. This includes the testing for certification of EHR software products and networks.

Mobility is a gem for storing and retrieving translations as attributes on a class. These translations could be the content of blog posts, captions on images, tags on bookmarks, or anything else you might want to store in different languages. Storage of translations is handled by customizable "backends" which encapsulate different storage strategies. The default way to store translations is to put them all in a set of two shared tables, but many alternatives are also supported, including translatable columns and model translation tables, as well as database-specific storage solutions such as json/jsonb and Hstore (for PostgreSQL).

Networking and sockets in scripting languages is difficult and often overcomplicated! Monasic is a server daemon (service) which does all the low level work to create a simple message-based environment, allowing easy access to networking via scripts.
