Pry
A runtime developer console and IRB alternative
Pry is a powerful alternative to Ruby’s default REPL that doubles as a runtime exploration and debugging toolkit. It offers command-driven navigation of objects and modules, syntax-highlighted input, command history, and the ability to switch contexts or “cd” into objects to inspect their methods and state. Features like show-source and show-doc reveal the implementation or documentation of methods without leaving the console, while edit-method lets you jump into an editor, modify code, and reload it on the fly. Dropping binding.pry into application code creates interactive breakpoints, making it easy to poke at variables, step through logic (with plugins like pry-byebug), and test hypotheses. An extensible command system and a rich plugin ecosystem add profiling, colorized output, paging, and Git integration. In day-to-day development, Pry shortens the feedback loop and turns debugging into an exploratory, conversational workflow. -

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. -

SimpleCov
Code coverage for Ruby with a powerful configuration library
Code coverage for Ruby with a powerful configuration library and automatic merging of coverage across test suites. SimpleCov is a code coverage analysis tool for Ruby. It uses Ruby's built-in Coverage library to gather code coverage data, but makes processing its results much easier by providing a clean API to filter, group, merge, format, and display those results, giving you a complete code coverage suite that can be set up with just a couple lines of code. SimpleCov/Coverage track covered ruby code, gathering coverage for common templating solutions like erb, slim and haml is not supported. In most cases, you'll want overall coverage results for your projects, including all types of tests, Cucumber features, etc. SimpleCov automatically takes care of this by caching and merging results when generating reports, so your report actually includes coverage across your test suites and thereby gives you a better picture of blank spots. -

Whenever
Cron jobs in Ruby
Whenever (javan/whenever) is a Ruby gem that provides a clean, Ruby DSL for defining and managing cron jobs within your application. Rather than editing system cron tables by hand, you describe scheduled tasks in a schedule.rb file using methods like every, runner, command, or rake. The gem then compiles this schedule into a standard crontab format and installs it for you, handling all the necessary quoting, environment setup, and command path resolution. It supports specifying execution contexts, output redirection, and interval offsets (e.g., “every 5 minutes between 9-5 on weekdays”). You can also write conditional logic around which jobs run on different environments or servers. Because it's integrated with your codebase, Whenever keeps your cron definitions versioned, testable, and maintainable alongside the rest of your project rather than buried in server configuration. -

ciao
HTTP checks & tests (private & public) monitoring
HTTP checks & tests (private & public) monitoring - check the status of your URL. ciao checks HTTP(S) URL endpoints for a HTTP status code (or errors on the lower TCP stack) and sends a notification on status change via E-Mail or Webhooks. It uses Cron syntax to schedule the checks and comes along with a Web UI and a RESTful JSON API. Create an open-source web application for checking URL statuses with a UI and a REST API which is easy to install and maintain (no external dependencies like Databases, Caches, etc.) in public and private environments. -

httplog
Log outgoing HTTP requests in ruby
Log outgoing HTTP requests made from your application. Helps with debugging pesky API error responses, or just generally understanding what's going on under the hood. In theory, it should also work with any library built on top of these. But the difference between theory and practice is bigger in practice than in theory. This is very much a development and debugging tool; it is not recommended to use this in a production environment as it is monkey-patching the respective HTTP implementations. You have been warned - use at your own risk. Just like in Rails, you can filter the values of sensitive parameters by setting the filter_parameters to an array of (lower case) keys. The value for "password" is filtered by default. Please note that this will only filter the request data with well-formed parameters (in the URL, the headers, and the request data) but not the response. It does not currently filter JSON request data either, just standard "key=value" pairs in the request body. -

CSS-Only Chat
A truly monstrous async web chat using no JS whatsoever
css-only-chat is a proof-of-concept demonstration that implements a functioning chat interface using only HTML and CSS, without any JavaScript or backend logic. The project showcases creative use of CSS selectors, checkboxes, labels, and the :checked pseudo-class to mimic interactive behaviors normally handled by JavaScript. Messages are pre-written in the HTML and displayed based on user interaction, making it more of a playful experiment than a real messaging platform. Its main purpose is to illustrate the limits of CSS as a programming and UI tool, serving as both an educational example and a bit of humor within the developer community. By pushing CSS beyond its conventional role, it demonstrates how user interfaces can be simulated through styling tricks and static structures. Although not suitable for production use, it stands as a fun exercise in front-end creativity and unconventional coding challenges. -

GitHub Markup
Determines which markup library to use to render a content file
This library is the first step of a journey that every markup file in a repository goes on before it is rendered on GitHub.com. GitHub-markup selects an underlying library to convert the raw markup to HTML. See the list of supported markup formats provided. The HTML is sanitized, aggressively removing things that could harm you and your kin—such as script tags, inline-styles, and class or id attributes. Syntax highlighting is performed on code blocks. See github/linguist for more information about syntax highlighting. The HTML is passed through other filters that add special sauce, such as emoji, task lists, named anchors, CDN caching for images, and autolinking. The resulting HTML is rendered on GitHub.com. The dependencies listed are required if you wish to run the library. You can also run script/bootstrap to fetch them all. -

Jekyll::Gzip
Generate gzipped assets and files for your Jekyll site at build time
Generate gzipped assets and files for your Jekyll site at build time. Performance in web applications is important. You know that, which is why you have created a static site using Jekyll. But you want a bit more performance. You're serving your assets and files gzipped, but you're making your webserver do it? Why not just generate those gzip files at build time? And with the maximum compression too? Jekyll::Gzip does just that. Add the gem to your Jekyll application and when you build your site it will generate gzip files for all text based files (HTML, CSS, JavaScript, etc). Zlib's gzipping capabilities don't quite squeeze all the compression out of our files that we could want. If you want a slower but better compression algorithm, check out Jekyll::Zopfli. Zopfli is about the best compression we can get out of the gzip format, but there's more! Brotli is a relatively new compression format that is now supported by many browsers and can produce even smaller files. -

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.
