Qoa is a simple machine learning library for Ruby, including a basic feedforward neural network implementation with backpropagation.

Caches the results of allowlisted SELECT queries (and MongoDB finds) across requests, below the ORM, with per-rule TTLs computed from the result.

A gem that removes duplicates when multiple copies of a que job are enqueued.

Isomorphically Render Liquid in Rails and JS

Quonfig — feature flags and live config, stored as files in git.

Extends Rack with AI capabilities including request classification, content moderation, smart caching, and security features

Tool that checks a Ruby application server for Rack compliancy

A comprehensive AI toolkit for Rails with multi-provider support, context awareness, and performance optimizations

Measures the Rails Heft Index (RHI), a weighted performance score based on realistic Rails 8+ workloads across Active Record, caching, views, jobs, and image processing.

Drop-in improvement for Rails cache

RailsGlyphs is an essential SVG icon library built exclusively for Ruby on Rails projects!

A Rails engine that adds structured, pluggable health check endpoints to any Rails app. Includes 11 built-in checks (database, cache, Redis, SMTP, Sidekiq, SolidQueue, GoodJob, Resque, disk, memory, HTTP), parallel execution via Concurrent::Future, result caching, Prometheus metrics, check groups, per-environment toggling, boot-time validation, and a Prometheus-compatible /metrics endpoint. Drop-in replacement for OkComputer.

rails_named_cache lets a Rails application register several ActiveSupport::Cache::Store instances by name and read them back with Rails.cache(:memory), Rails.cache(:redis), Rails.cache(:pricing) and so on. Rails.cache keeps working exactly as before, stores are never wrapped, and no new caching API is introduced.

Lightweight ops dashboard for Rails: run seeds, execute rake tasks, inspect environment variables, and manage workers. All behind HTTP Basic Auth, blocked in production by default.

A mountable Rails engine providing real-time metrics, job monitoring, cache analytics, and error tracking for applications built on the Solid trifecta.

Packages the yabeda ecosystem and health-monitor-rails into a single, opinionated kit for running Rails applications on Kubernetes: Puma, Sidekiq and SolidQueue runtime metrics in Prometheus text format on an in-process /metrics endpoint (default port 9394), plus a /healthz endpoint wired for liveness/readiness/startup probes. No sidecar, no separate collector. It also hosts the schedulers that let a job executor scale to zero without stranding its recurring jobs: a supervised SolidQueue scheduler thread, and a supervised sidekiq-cron poller for Sidekiq.

A comprehensive Rails profiler with web debug toolbar, profiling UI, SQL analysis, performance timeline, and MCP server integration

RailsQuery provides a declarative abstraction for fetching, caching, and managing remote or expensive data in Rails applications. Inspired by modern data-fetching patterns, it introduces query lifecycle concepts such as caching, stale-while-revalidate, automatic invalidation, and request deduplication, while remaining idiomatic to the Rails ecosystem.

Rails simple event sourcing engine.
