Faraday
Simple, but flexible HTTP client library, with support for backends
Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters (such as Net::HTTP) and embraces the concept of Rack middleware when processing the request/response cycle. You probably don't want to use Faraday directly in your project, as it will lack an actual client library to perform requests. Instead, you probably want to have a look at Awesome Faraday for a list of available adapters. The best starting point is the Faraday Website, with its introduction and explanation. This library aims to support and is tested against the currently officially supported Ruby implementations. This means that, even without a major release, we could add or drop support for Ruby versions, following their EOL. Currently that means we support Ruby 2.6+. You can also install the faraday_middleware extension gem to access a collection of useful Faraday middleware. -

Opal jQuery
jQuery for Opal
opal-jquery provides DOM access to opal by wrapping jQuery (or zepto) and providing a nice ruby syntax for dealing with jQuery instances. opal-jquery provides an Element class, whose instances are toll-free bridged instances of jQuery objects. Just like ruby arrays are just javascript arrays, Element instances are just jQuery objects. This makes interaction with jQuery plugins much easier. Also, Element will try to bridge with Zepto if it cannot find jQuery loaded, making it ideal for mobile applications as well. The request is actually triggered inside the HTTP. get method, but due to the async nature of the request, the callback and errback handlers can be added anytime before the request returns. -

Phlex
Object-oriented views in Ruby
Phlex is a Ruby-based framework for building HTML and SVG views using object-oriented programming principles, offering a unique alternative to traditional template systems like ERB. It allows developers to write UI components entirely in Ruby, providing full control over structure, logic, and rendering without mixing HTML and templating syntax. One of its key advantages is performance, as it can render HTML extremely quickly while maintaining predictable scaling even with complex component hierarchies. Phlex integrates seamlessly with Ruby on Rails and supports common tools such as Tailwind CSS, Stimulus, and Turbo, making it easy to incorporate into modern Rails applications. It also emphasizes safety and maintainability by preventing common issues such as cross-site scripting through structural design and strict data handling. Developers benefit from reusable components, modular architecture, and the ability to stream content for improved performance and user experience. -

EventMachine
EventMachine, fast, simple event-processing library for Ruby programs
EventMachine is an event-driven I/O and lightweight concurrency library for Ruby. It provides event-driven I/O using the Reactor pattern, much like JBoss Netty, Apache MINA, Python's Twisted, Node.js, libevent and libev. Extremely high scalability, performance and stability for the most demanding production environments. An API that eliminates the complexities of high-performance threaded network programming, allowing engineers to concentrate on their application logic. This unique combination makes EventMachine a premier choice for designers of critical networked applications, including Web servers and proxies, email and IM production systems, authentication/authorization processors, and many more. EventMachine has been around since the early 2000s and is a mature and battle-tested library. -

Linguist
Detect blob languages, suppress generated files and generate graphs
This library is used on GitHub.com to detect blob languages, ignore binary or vendored files, suppress generated files in diffs, and generate language breakdown graphs. Linguist is a Ruby library so you will need a recent version of Ruby installed. There are known problems with the macOS/XCode supplied version of Ruby that causes problems installing some of the dependencies. Accordingly, we highly recommend you install a version of Ruby using Homebrew, rbenv, rvm, ruby-build, asdf or other packaging system, before attempting to install Linguist and the dependencies. Linguist uses charlock_holmes for character encoding and rugged for libgit2 bindings for Ruby. These components have their own dependencies. A repository's languages stats can also be assessed from the command line using the github-linguist executable. Without any options, github-linguist will output the breakdown that correlates to what is shown in the language stats bar. -

Mechanize
Mechanize is a ruby library that makes automated web interaction easy
The Mechanize library is used for automating interaction with websites. Mechanize automatically stores and sends cookies, follows redirects, and can follow links and submit forms. Form fields can be populated and submitted. Mechanize also keeps track of the sites that you have visited as a history. This library was heavily influenced by its namesake in the Perl world. Mechanize#transact runs the given block and then resets the page history. I.e. after the block has been executed, you're back at the original page; no need to count how many times to call the back method at the end of a loop (while accounting for possible exceptions). -
15
Pedestal
The Pedestal Server-side Libraries
Pedestal is a set of libraries that we use to build services and applications. It runs in the back end and can serve up whole HTML pages or handle API requests. There are a lot of tools in that space, so why did we build Pedestal? We had two main reasons. Pedestal is designed for APIs first. Most web app frameworks still focus on the "page model" and server-side rendering. Pedestal lets you start simple and add that if you need it. Pedestal makes it easy to create "live" applications. Applications must respond with immediate feedback even while some back-end communication goes on. Pedestal makes it easy to deliver server-sent events and asynchronous updates. Pedestal works with a huge variety of containers and deployment options. Deploy applications or microservices on unikernels, Docker containers, or JAR files. Pedestal supports Tomcat, Jetty, Immutant (with Undertow), Vert.x, nginx, and Netty. -

Prawn
Fast, Nimble PDF Writer for Ruby
Prawn is a pure Ruby PDF generation library that provides a lot of great functionality while trying to remain simple and reasonably performant. Extensive text rendering support, including flowing text and limited inline formatting options. Comprehensive internationalization features, including full support for UTF-8 based fonts, right-to-left text rendering, fallback font support, and extension points for customizable text wrapping. Support for PDF outlines for document navigation. Low level PDF features, allowing users to create custom extensions by dropping down all the way to the PDF object tree layer. (Mostly useful to those with knowledge of the PDF specification). If you are looking for a highly flexible PDF document generation system, Prawn might be the tool for you. It is not a reporting tool or a publishing toolchain, though it could be fairly easily used to build those things. -

Rein
Database constraints made easy for ActiveRecord
Data integrity is a good thing. Constraining the values allowed by your application at the database level, rather than at the application level, is a more robust way of ensuring your data stays sane. Unfortunately, ActiveRecord doesn't encourage (or even allow) you to use database integrity without resorting to hand-crafted SQL. Rein (pronounced "rain") adds a handful of methods to your ActiveRecord migrations so that you can easily tame the data in your database. All methods in the DSL are automatically reversible, so you can take advantage of reversible Rails migrations. -

Resque
Ruby library for creating background jobs and processing them
Resque is a Redis-backed Ruby library for creating background jobs, placing them on multiple queues, and processing them later. Resque (pronounced like "rescue") is a Redis-backed library for creating background jobs, placing those jobs on multiple queues, and processing them later. Background jobs can be any Ruby class or module that responds to perform. Your existing classes can easily be converted to background jobs or you can create new classes specifically to do work. Or, you can do both. Resque is heavily inspired by DelayedJob (which rocks) and comprises three parts, a Ruby library for creating, querying, and processing jobs, a Rake task for starting a worker which processes jobs, a Sinatra app for monitoring queues, jobs, and workers. Resque workers can be distributed between multiple machines, support priorities, are resilient to memory bloat / "leaks," are optimized for REE (but work on MRI and JRuby), tell you what they're doing, and expect failure. -

Ruby-processing
Bridge between the Processing creative-coding framework and Ruby
Ruby-processing is a bridge between the Processing creative-coding framework (originally Java-based) and the Ruby language, created to let developers and artists write Processing sketches using Ruby syntax. It enables the well-known graphics, animation, interaction and sketching patterns of Processing in a Ruby environment, which can be appealing to those who prefer Ruby’s syntax or already live in the Ruby ecosystem. Though the project is now deprecated and newer alternatives exist, it remains an excellent historical example of how to embed a drawing/graphics API into another language and how creative coding communities evolve. For educators or artists exploring coding visually, Ruby-Processing provided a low-barrier entry by combining a high-level language (Ruby) with an expressive graphics library. It also demonstrates how open-source communities wrap frameworks into new environments for accessibility and experimentation. -

factory_bot
A library for setting up Ruby objects as test data
factory_bot is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class (user, admin_user, and so on), including factory inheritance. factory_bot provides a framework and DSL for defining and using factories - less error-prone, more explicit, and all-around easier to work with than fixtures. Each factory has a name and a set of attributes. The name is used to guess the class of the object by default. It is recommended that you have one factory for each class that provides the simplest set of attributes necessary to create an instance of that class. If you're creating ActiveRecord objects, that means that you should only provide attributes that are required through validations and that do not have defaults. Other factories can be created through inheritance to cover common scenarios for each class. -

Rpg.NET
Performance enhancement API for RPG Maker XP, VX, VXA.
Rpg.NET is an API built using the .NET Framework for both improving performance and enhancing the RPG Maker series (XP, VX, and VXA). Contained within are various functions and classes that extend the ability of RPG Maker in areas such as graphics, audio, and Windows API interop. Included is a Ruby script that is the wrapper around the library, so it can be used as any other script within your game. -

CanCan
Authorization Gem for Ruby on Rails
CanCan is an authorization library for Ruby on Rails that helps manage user permissions in a clean and consistent way. It centralizes all authorization logic in a single Ability class, where you define what actions each type of user can or cannot perform on different resources. Developers then use helpers like authorize! in controllers or can? in views to enforce those rules without scattering permission logic across the application. It supports defining permissions using conditions, allowing granular access based on attributes like ownership or role. Because it abstracts authorization cleanly, applications stay easier to read, test, and maintain as business rules evolve. Though no longer actively maintained in its original form, CanCan inspired forks and successors (such as CanCanCan) that continue to be widely used in Rails projects.
