Activejob Locks is an ActiveJob addon that will lock workers based on queue or work payload

activejob-temporal bridges Rails ActiveJob with Temporal's durable execution engine. It provides a drop-in ActiveJob adapter, Temporal workflows, and supporting tooling so Rails apps gain fault-tolerant scheduling, retries, and observability with minimal changes.

ActiveModel::Caching is a versatile gem for managing structured, temporary data using a caching backend, typically Rails cache for Rails applications. This gem provides an easy-to-use API for storing, retrieving, and manipulating data structures like scalars, lists, and JSON, making it simple to handle transient data without adding extra dependencies.

ActiveShopifyGraphQL provides an ActiveRecord-like interface for interacting with Shopify's GraphQL APIs, supporting both Admin API and Customer Account API with automatic query building and response mapping.

A metadata backend that lets Active Storage store its Blob, Attachment, and VariantRecord rows in Amazon DynamoDB (through the aws-record gem) instead of Active Record. Blob bytes still flow through any Active Storage Service (Disk, S3, ...); only the metadata lives in DynamoDB. Implements the generic custom Active Storage backend contract.

This library contains functionality to send/store BI and AB-testing data

Pension Guidance Booking Locations API adapter

chats is a drop-in gem to add chat messaging to your Rails app. It implements a real-time messaging engine for Ruby on Rails 8+ apps: direct messages (DMs), group chats, image attachments, emoji reactions, read receipts, unread badges, and typing indicators. All rendered server-side and updated live with Hotwire (Turbo Streams over Action Cable), so it ships with zero custom JavaScript build steps and works with importmaps out of the box. Any model can converse via a single `acts_as_messager` macro (users, organizations, support agents — participants are polymorphic), conversations can be optionally attached to any domain record via `acts_as_chat_subject` (so users can chat about a specific order, a listing, a booking), and the whole inbox UI is overridable view-by-view like Devise. It exposes small adapter seams a blocked-users lookup, a `can_message` policy, and a notifier hook; so it snaps onto the `moderate` gem for Trust & Safety (report/block/filter, DSA + app-store compliance) and onto any notification system (like the `noticed` gem) without any hard dependencies. Messages support soft deletion, editing, system messages posted by your app, per-sender rate limiting, and optional encryption at rest.
