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.

Avo is a very custom Admin Panel Framework, Content Management System, and Internal Tool Builder for Ruby on Rails that saves engineers and teams months of development time.

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.

SIGAR (System Information Gatherer and Reporter) is a cross-platform, cross-language library and command-line tool for accessing operating system and hardware level information in Java, Perl and .NET.

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.

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.

Grape is a Ruby framework for building REST-like APIs with a focus on simplicity and convention. It provides a DSL for declaring endpoints, parameters, formats, and validation rules, making it easy to build consistent and documented APIs. Grape supports multiple content types (JSON, XML, etc.), versioning, error handling, and authentication hooks, which are crucial for maintaining long-lived APIs. It integrates well with frameworks like Rails or Sinatra but can also be used standalone for microservices. Built-in tools like parameter coercion, strong validations, and automatic documentation (via Swagger integrations) reduce boilerplate and improve maintainability. Because it’s lightweight and purpose-built, Grape is popular in service-oriented architectures where clean, well-structured APIs are central.

Official repository of the bootstrap_form gem, a Rails form builder that makes it super easy to create beautiful-looking forms using Bootstrap 5. bootstrap_form is a Rails form builder that makes it super easy to integrate Bootstrap v5-style forms into your Rails application. It provides form helpers that augment the Rails form helpers. bootstrap_forms's form helpers generate the form field and its label and all the Bootstrap mark-up required for proper Bootstrap display. bootstrap_form. You can also put the error messages after the label, or turn off bootstrap_form's validation error handling and do it yourself. Note that this applies to Rails-generated validation messages. HTML 5 client-side validation and Rails validation out of the box doesn't really work well together. Mark-up for Bootstrap horizontal forms (labels to the left of their fields, like a traditional desktop application), if that's what you want.

scriptHelper is a Java library allowing a simple integration between Java code and various script languages. This library also allows to debug these scripts in the context of a Java program.

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 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.

Mongoid is the officially supported ODM (Object-Document-Mapper) framework for MongoDB in Ruby. This Mongoid community organization is a group of open-source contributors around the Mongoid ODM not affiliated with the company, MongoDB. Mongoid is customarily configured through a mongoid.yml file that specifies options and clients. The simplest configuration is as follows, which configures Mongoid to talk to a MongoDB server at “localhost:27017” and use the database named “mongoid”. If you are not using Ruby on Rails, Mongoid configuration must be loaded manually. This can be done via the Mongoid.load! method, which takes the configuration file path as its argument. It is also possible to configure Mongoid directly in Ruby, without using a configuration file. This configuration style does not support the concept of environments - whatever configuration is provided, it is applied to the current environment, but it does support defining multiple clients.

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.

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 ! Andrew Hang Chen and other maintainers who feel importance of TDD in cr

TappedAudio is an audio library with an emphasis on the programming interface -- agnostic to the backend, written in highly-encapsulated C++ and using SWIG to present a unified API for C++, Python, Ruby, etc., regardless of the underlying audio platform.
