    Blueprint CSS

    Blueprint CSS

    A CSS framework that aims to cut down on your CSS development time

    Blueprint CSS is a CSS framework aimed at accelerating layout and typographic design by providing robust base styles, grid systems, and reusable UI components. It combines normalized defaults with helpful utilities—such as column layouts, form styling, and typography helpers—so developers can build responsive sites with less repetitive CSS. Because it’s designed as a structural foundation rather than a themed UI kit, it’s easy to layer branding and custom design on top without fighting the base styles. The framework includes mixins, modifier classes, and responsive breakpoints so layouts adapt fluidly across screen sizes. By starting with a consistent baseline, Blueprint CSS reduces cross-browser quirks and gives designers confidence in spacing, proportion, and element alignment. Teams often use it as the “CSS backbone” of internal tools, web products, or component libraries.

    Compass

    Compass

    Stylesheet authoring framework

    Compass is a stylesheet authoring framework built on top of Sass that provides a rich set of mixins, functions, and helpers for writing maintainable CSS. It offers abstractions for vendor prefixes, cross-browser compatibility fixes, and reusable UI patterns like grids, buttons, and typography helpers. With Compass, developers can write cleaner Sass code that compiles into consistent CSS across browsers without hand-coding workarounds. The framework also includes a command-line tool for compiling Sass, managing sprite sheets, and integrating with build workflows. It was widely adopted in the era before modern CSS standards caught up with mixins and variables, helping developers speed up styling while reducing redundancy. While less dominant today, Compass remains an important historical tool that influenced the evolution of Sass and frontend best practices.

    DuckRails

    DuckRails

    Development tool to mock API endpoints quickly

    DuckRails is a development tool. Its main purpose is to allow developers to quickly mock API endpoints that for many possible reasons they can't reach at a specific time. The application allows creating new routes dynamically to which developers can assign static or dynamic responses. DuckRails is an open source development tool built using the Ruby on Rails framework. The purpose of the tool is to allow developers to easily mock API endpoints outside their applications. Knowing ruby is not required. It would just help you define ruby dynamic mocks easier (embedded ruby). No worries, you can still define dynamic responses by selecting Javascript as the mock’s body type. Instead of defining a mock to always respond with some static content, you can also configure it to dynamically resolve the content to serve. For example, you can access the original request’s parameters and headers and decide how you could respond.

    Hanami

    Hanami

    A flexible framework for maintainable Ruby apps

    Hanami is a modern Ruby web framework that aims to be lightweight, fast, and modular, in contrast to the monolithic design of Rails. It emphasizes separation of concerns, encouraging developers to structure applications into clear layers of controllers, views, entities, and repositories. Each component—like the router, model layer, or view rendering engine—can be used independently, which gives developers flexibility to build lean applications. Hanami promotes immutability, plain old Ruby objects, and minimized global state, which makes codebases more maintainable and testable. It supports multi-application setups within the same project, making it well-suited for larger service-oriented architectures. The framework is designed to provide Rails-like productivity while encouraging more explicit architecture and performance-conscious choices.

    Mobility

    Mobility

    Pluggable Ruby translation framework

    Mobility is a gem for storing and retrieving translations as attributes on a class. These translations could be the content of blog posts, captions on images, tags on bookmarks, or anything else you might want to store in different languages. Storage of translations is handled by customizable "backends" which encapsulate different storage strategies. The default way to store translations is to put them all in a set of two shared tables, but many alternatives are also supported, including translatable columns and model translation tables, as well as database-specific storage solutions such as json/jsonb and Hstore (for PostgreSQL).
