Rails + Hotwire + Stimulus overview

Classic modern-Rails stack: Ruby on Rails with Hotwire (Turbo Frames and Turbo Streams) for server-driven UI updates without writing JavaScript, and Stimulus for small, targeted client-side behaviors. ActiveRecord (PostgreSQL or MySQL), Active Job (with Sidekiq for background processing), Action Mailer, and Action Cable (WebSockets) are the canonical Rails companions. Tailwind CSS via the cssbundling-rails gem is the standard styling approach. Deployment commonly targets Heroku, Render, or Fly.io. This stack favors convention over configuration and maximizes developer productivity for feature-rich web applications.
