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. -

Bourbon
A lightweight sass tool set
Bourbon is a library of Sass mixins and functions that are designed to make you a more efficient style sheet author. It’s not recommended that you modify Bourbon’s files directly as it will make updating to future versions difficult, by overwriting your custom changes or causing merge conflicts. Import Bourbon at the beginning of application.scss. Any project styles that utilize Bourbon’s features must be imported after Bourbon. Bourbon supports Internet Explorer 11+ and the latest versions of Chrome, Firefox, Safari, and Edge. Bourbon is maintained by the thoughtbot design team. It is funded by thoughtbot, inc. and the names and logos for thoughtbot are trademarks of thoughtbot, inc. You can target installation into a specific directory using the path flag. Bourbon is copyright © 2011-2020 thoughtbot, inc. It is free software, and may be redistributed under the terms specified in the license. -

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. -

tobi try
Fresh directories for every vibe
try is a lightweight Ruby command-line tool for managing short-lived experiment directories. It is built for developers who constantly create quick tests, prototypes, proof-of-concepts, and late-night coding experiments that usually get lost across temporary folders. The tool gives every experiment a dated home, then makes it easy to find and reopen past work with fuzzy search. It favors simplicity, using a one-file Ruby script with no dependencies and very little setup. Smart sorting brings recently used experiments to the top, which helps users jump back into active ideas without remembering exact folder names. It is ideal for developers who want a low-friction workspace system for creative technical exploration without turning every experiment into a full project. -

Dependabot
Dependabot's core logic for creating update PR's
Dependabot-Core is the library at the heart of Dependabot security/version updates. Use it to generate automated pull requests updating dependencies for projects written in Ruby, JavaScript, Python, PHP, Dart, Elixir, Elm, Go, Rust, Java and .NET. It can also update git submodules, Docker files, and Terraform files. Check for the latest version of a dependency that's resolvable given a project's other dependencies. Generate updated manifest and lockfiles for a new dependency version. Generate PR descriptions that include the updated dependency's changelogs, release notes, and commits. -

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. -

15
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). -
16
Redis Store
Cache Redis stores for Ruby web frameworks
Redis Store provides a full set of stores (Cache, I18n, Session, HTTP Cache) for modern Ruby frameworks like: Ruby on Rails, Sinatra, Rack, Rack::Cache and I18n. It supports object marshaling, timeouts, single or multiple nodes, and namespaces. -
17
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. -

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. -

FriendlyId
FriendlyId is the “Swiss Army bulldozer” of slugging
FriendlyId is a Rails gem that provides human-readable slugs for ActiveRecord models, replacing numeric IDs in URLs with meaningful strings. For example, instead of /articles/123, you can have /articles/my-first-post. It integrates with ActiveRecord to generate slugs automatically based on attributes (like a title) and manages uniqueness, history, and slug regeneration when records change. FriendlyId also supports features like slug candidates, scoped slugs, and reserved word handling to avoid conflicts. It includes extensions to keep old slugs working as redirects, so links don’t break when content is renamed. By improving readability, SEO, and user-friendliness, FriendlyId has become the de facto solution for slugging in Rails applications. -
21
GH Archive
GH Archive is a project to record the public GitHub timeline
GH Archive collects public GitHub activity and preserves it as a historical dataset for analysis. It polls GitHub’s event feed and groups the raw responses into compressed hourly JSON archives. The records cover actions such as commits, forks, issue activity, comments, and repository membership changes. Researchers can download specific hours, days, or longer periods with ordinary HTTP tools and process the events in their own systems. The dataset is also published through Google BigQuery for large-scale SQL-style exploration without downloading every archive. Its structure supports trend analysis, visualizations, machine learning, and open-source ecosystem research. The repository contains the crawler, supporting scripts, and website code, while the actual event files are hosted separately. -

24
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. -
