Unifig support for Rails.

UniOne Web API for Rails: API client, Action Mailer delivery method, webhooks

Union Station Rails hooks.

A mountable Rails engine wrapping the UniRate API (https://unirateapi.com) — free currency exchange rates, conversion, supported-currency listings, and VAT rates. Ships a configurable client, ActionView helpers (unirate_rate, unirate_convert), and a JSON proxy controller. Zero runtime dependencies beyond Rails.

A Rails adaptor that encapsulate measurements and their units in Ruby on Rails.

Make your model uniq and identifiable through a readable name.

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.

Render SVG icons inline in Rails views, resolve them through library/name references and aliases, and download popular icon sets (Heroicons, Lucide, Tabler, Feather, and more)

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.

Unreliable helps uncover bugs in Rails apps that rely on ambiguous database ordering. Installing it makes both your app and your test suite more robust.

Rails 8 (PR #53281) sorts schema.rb columns alphabetically. That breaks db:schema:load parity with production, Postgres column-alignment padding, add_column :after/:before, and bulk-import pipelines that depend on SELECT * column order. This gem prepends ActiveRecord::SchemaDumper to dump columns in the order the database actually stores them.

Gemified UOL frontend framework

This gem adds to ActiveRecord a method update_by_case that allows you to update multiple records based on case values on a single database hit.
