description	Ruby on Rails MVC framework with Active Record and conventions. Use for rapid development.

Ruby on Rails

Rails is a web application framework that includes everything needed to create web applications. Rails 8 (2025) simplifies deployment (Kamal) and reduces dependencies (Solid Cache/Queue).

When to Use

• Startups: The "One Person Framework". Build a full SaaS alone.
• Rapid Development: Convention over Configuration makes you move fast.
• No-Build: Rails 8 pushes hard for "no-build" setups with Propshaft and import maps.

Quick Start

# app/controllers/posts_controller.rb
class PostsController < ApplicationController
  def index
    @posts = Post.all
  end
end

Core Concepts

The "Solid" Stack (Rails 8)

• Solid Cache: DB-backed caching (replacing Redis for simple cases).
• Solid Queue: DB-backed background jobs.
• Solid Cable: DB-backed WebSocket handling. Rails 8 aims to let you deploy with just a SQLite/Postgres DB, no Redis required.

Hotwire

Build SAP-like responsiveness with HTML over the wire.

• Turbo: Fast navigation and partial page updates.
• Stimulus: Modest JavaScript frameworks for the remaining 10% of interactivity.
