Metasploit Framework
Metasploit Framework
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. -

RubyGems
Library packaging and distribution for Ruby
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. -

RSpec Rails
RSpec for Rails 5+
RSpec Rails brings the RSpec testing framework to Ruby on Rails as a drop-in alternative to its default testing framework, Minitest. In RSpec, tests are not just scripts that verify your application code. They’re also specifications (or specs, for short): detailed explanations of how the application is supposed to behave, expressed in plain English. RSpec follows semantic versioning, which means that “major version” upgrades (e.g., 2.x → 3.x) come with breaking changes. If you’re upgrading from version 2.x or below, read the rspec-rails upgrade notes to find out what to watch out for. In RSpec, assertions are called expectations, and every expectation is built around a matcher. When you expect(a).to eq(b), you’re using the eq matcher. RSpec Rails defines ten different types of specs for testing different parts of a typical Rails application. Each one inherits from one of Rails’ built-in TestCase classes, meaning the helper methods provided by default in Rails tests are available. -

FORTRAN Unit Test Framework (FRUIT)
FORTRAN Unit Test Framework FRUIT - TDD in FORTRAN
FORTRAN Unit Test Framework, written in FORTRAN 95. So that all FORTRAN features can be tested. FRUIT has assertion, fixture, setup, teardown, report, spec, driver generation. Rake used as build tool. Tutorials at http://fortranxunit.wiki.sourceforge.net The core testing part is in FORTRAN, this part can be used independent of the Ruby codes. The Ruby code is to make fixtures and reports easier. Rake is to build the project elegantly. This project also demonstrate a new way to build mixed language code in an alternative way than Make. Most of the FORTRAN are important in nature, used in nuclear and aerospace codes, etc, and maintained and written actively. Please help to bring TDD practices to the FORTRAN community. The change could be very hard, personally, I quit, since I could not make the change. I hope your organization will be successful. Enjoy a cup of fruit while maintaining FORTRAN !

Compass
Stylesheet authoring framework
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. -

Active Admin
The administration framework for Ruby on Rails applications
Active Admin is a Ruby on Rails plugin for generating administration style interfaces. It abstracts common business application patterns to make it simple for developers to implement beautiful and elegant interfaces with very little effort. Customizable global navigation allows you to create usable admin interfaces for your business. Use the bundled Devise configuration or implement your own authorization using the provided hooks. Use scopes to create sections of mutually exclusive resources for quick navigation and reporting. Add buttons, links or other content in the “Action Items” section on each screen. Index screens are available in many styles. The default, shown here, is a table view, but Active Admin also supports Grids, Blocks and a Blog view. Allow users to filter resources by searching strings, text fields, dates, and numeric values. Customize the sidebar sections with a simple DSL built in to Active Admin. -

Blueprint CSS
A CSS framework that aims to cut down on your CSS development time
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. -

Capistrano
Remote multi-server automation tool
A remote server automation and deployment tool written in Ruby. Capistrano extends the Rake DSL with methods specific to running commands on() servers. Capistrano is written in Ruby, but it can easily be used to deploy any language. If your language or framework has special deployment requirements, Capistrano can easily be extended to support them. Capistrano is bundled as a Ruby Gem. It requires Ruby 2.0 or newer. Capistrano can be installed as a standalone Gem, or bundled into your application. It is recommended to fix the version number when using Capistrano, and is therefore recommended to use an appropriate bundler. The capistrano-rails gem includes extras specifically designed for Ruby on Rails, specifically Asset Pipeline Support and Database Migration Support. Capistrano deploys using SSH. Thus, you must be able to SSH (ideally with keys and ssh-agent) from the deployment system to the destination system for Capistrano to work. -

Capybara
Acceptance test framework for 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. -

DuckRails
Development tool to mock API endpoints quickly
DuckRails is a development tool. Its main purpose is to allow developers to quickly mock API endpoints that for many possible reasons they can't reach at a specific time. The application allows creating new routes dynamically to which developers can assign static or dynamic responses. DuckRails is an open source development tool built using the Ruby on Rails framework. The purpose of the tool is to allow developers to easily mock API endpoints outside their applications. Knowing ruby is not required. It would just help you define ruby dynamic mocks easier (embedded ruby). No worries, you can still define dynamic responses by selecting Javascript as the mock’s body type. Instead of defining a mock to always respond with some static content, you can also configure it to dynamically resolve the content to serve. For example, you can access the original request’s parameters and headers and decide how you could respond. -
