Down
Streaming downloads using Net::HTTP, http.rb or HTTPX
Down is a small, reliable Ruby library for downloading files that favors correctness, streaming, and clear error handling. It follows redirects safely, supports timeouts and retries, and streams responses to disk to keep memory usage low—ideal for large downloads or server environments. The API returns file-like objects (often Tempfile) with helpful metadata such as original filename and content type, which plays nicely with file-attachment libraries and background jobs. Multiple HTTP backends are supported, letting you choose between Net::HTTP or faster/feature-rich clients while keeping a consistent interface. It exposes distinct exception classes and content validation options, so callers can differentiate transient network issues from invalid responses. In practice, Down is often used as the dependable download layer in upload/processing pipelines where robustness matters more than raw feature bloat. -

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. -

Learning-SICP
Collection of Chinese cultural projects and course learning materials
Learning-SICP is a community project that localizes the MIT course “Structure and Interpretation of Computer Programs” (SICP) and curates complementary study materials for learners, especially Chinese-speaking Scheme/Lisp students. It focuses on translating the official lecture subtitles into Chinese while preserving the original English content for reference, providing an approachable path to a classic foundational course in computer science. The repository organizes translated subtitles, lecture indices, and supporting documents so learners can follow along with the full video series and consult the book and related readings as they study. Beyond subtitles, it aggregates links to the SICP text, environment setup guides, extended exercises, and FAQ resources to smooth first-time setup and deepen understanding of the material. -

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. -

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. -

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. -

Pundit
Minimal authorization through OO design and pure Ruby classes
Pundit (varvet/pundit) is a Ruby gem that provides a simple and effective framework for adding authorization logic to Rails (or other Ruby) applications. It centers around policy classes—one policy per model or resource—that define what actions a given user is permitted to perform (e.g., show?, update?, destroy?). Each policy method returns a boolean, and can be structured using combinators or shared logic to keep things DRY. In controllers and views, Pundit provides helpers like authorize, policy_scope, and policy to enforce those rules cleanly and consistently. The policy_scope feature is especially helpful—it restricts index or list queries to only the records the current user can see by applying scopes defined in the policy class. Pundit encourages placing authorization logic close to the model domain without muddling controllers or views, making permissions easier to reason about and testable. -

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. -

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. -

ajax-datatables-rails
A wrapper around DataTable's ajax methods that allow synchronization
DataTables is a nifty jQuery plugin that adds the ability to paginate, sort, and search your HTML tables. When dealing with large tables (more than a couple of hundred rows) however, we run into performance issues. These can be fixed by using server-side pagination, but this breaks some DataTables functionality. ajax-data tables-rails is a wrapper around DataTables ajax methods that allow synchronization with server-side pagination in a Rails app. It was inspired by this Railscast. I needed to implement a similar solution in a couple of projects I was working on, so I extracted a solution into a gem. The final goal of this gem is to generate JSON content that will be given to jQuery DataTables. All the data table customizations (header, tr, td, CSS classes, width, height, buttons, etc.) must take place in the javascript definition of the data table. jQuery DataTables is a very powerful tool with a lot of customization available. Take the time to read the doc. -
