UI components for Rails views in the spirit of form_for. Builders for index tables (sortable, deferred, kept live by Turbo Streams), detail lists, forms, cards, page headers and loading skeletons; a Turbo Frame modal, a confirm dialog and flash toasts; menus, tabs, tooltips, local times, copy buttons, autogrowing textareas and UUID inputs as self-registering custom elements; and AI chat components — transcripts, streamed replies, tool-call timelines, plans, permission requests and a composer — kept live by Turbo Streams. Plain helpers styled with Tailwind CSS v4 (required; the host's build compiles the gem's component CSS), with no Stimulus.

A Rails engine that adds passkey registration and authentication backed by Active Record. Self-contained, pure-Ruby WebAuthn ceremonies (CBOR, COSE, attestation and assertion verification) with stateless signed challenges — no external gems.

Upkeep records the data and identity dependencies used while Rails renders a view, then updates subscribed frames when matching application data changes.

A jQuery plugin provides to display time in user's timezone.

Serializable and validatable value objects for ActiveRecord

The Rails half of the VEKTIS Impact Tracking data path. Ships the ingest client, the emit seam, off-request delivery, a controller concern, and the browser handoff for @vektis-io/tracker. Explicit-call-only: the only events on the wire are the ones your code asks for.

ViewComponents for the Velvet Design System

bind_render and bind_render_each resolve a partial once and then call the method ActionView already compiled for it. Partials stay ordinary partials: backtraces, locals, strict locals, development reloading and fragment cache digests all keep working.

Define styles as Ruby hashes next to your components. Compiles to deterministic atomic classes with per-property merging, conditions, breakpoints, dynamic values and CSS-variable theming. No JavaScript build step.

Concerns to help manage attributes in View Components

Provide feature to search view files from your browser.

Administrate is heavily inspired by projects like Rails Admin and ActiveAdmin, but aims to provide a better user experience for site admins, and to be easier for developers to customize. To do that, we're following a few simple rules: - No DSLs (domain-specific languages) - Support the simplest use cases, and let the user override defaults with standard tools such as plain Rails controllers and views. - Break up the library into core components and plugins, so each component stays small and easy to maintain.

vue_live compiles .vue single-file components on the fly, in Ruby, and serves them to the browser as native ES modules. It works with any Rack application (Sinatra, Roda, plain Rack), detects a Rails application and configures itself as a Railtie, and coexists with Sprockets, Propshaft, Webpacker, importmap-rails and jsbundling without touching their paths. An optional Node backend (via @vue/compiler-sfc) adds <script setup>, TypeScript and CSS preprocessors.

WebGit is an embeddable Sinatra app that provides an in-browser visual interface to a simple but effective Git workflow. For educational purposes.
