A comprehensive UI component library for Rails applications. Provides reusable components in three formats: ERB partials, Phlex components, and ViewComponents. Built with Tailwind CSS 4 and Stimulus.js.

Use Frontyard in your rails app to simplify the use of Phlex views.

GRSX — JSX-flavored templates for Ruby, powered by Phlex

Description of InnerPlan.

Build Rails applications focusing on your business problem not the code.

PhlexKit brings the shadcn/ui component catalog to Phlex and Rails, replacing Tailwind with co-located vanilla CSS per component plus a global :root design-token theme. phlex-reactive is an optional, per-component integration — never a required dependency. Assets ship precompiled-static, so no host build step.

Stimulus.js and Sorbet support for Phlex components

Pinmark adds a dev-only floating overlay to any Rails app. Click a component or any element on the page, leave a comment, and Claude Code consumes the queue via MCP — closing the loop between visual feedback and source edits. Works with Phlex, ViewComponent, and ERB partials.

Proscenium integration for Phlex

Build phlex based forms using Rails conventions

ruby_ui_admin is an admin framework for Rails, rendered with RubyUI (Phlex) components and authorized with action_policy.

Provides `rails g ruby_ui_scaffold` — a drop-in replacement for `rails g scaffold` that generates model, controller, routes, tests, and Phlex view classes wired to ruby_ui components (Input, Textarea, Checkbox, Button, Table, FormField, etc.).

All shadcn/ui v4 components ported to Phlex with Stimulus controllers, 7 base color themes, 17 accent colors, and Rails generators.

Provides component-scoped CSS encapsulation using [data-capsule] attributes for Phlex components, ViewComponent components, and ERB templates. Styles are automatically scoped to prevent leakage between components. Inspired by component-based CSS approaches like Angular's view encapsulation and CSS modules. Works with Rails and can be used standalone in other Ruby frameworks (Sinatra, Hanami, etc.) or plain Ruby scripts.
