# Ruby on Rails — Build Happy. Ship Fast. Scale Forever.

> The definitive case for Ruby and Ruby on Rails: the language and framework powering Shopify, GitHub, Airbnb, and thousands of startups — with a curated Get Started hub.

Ruby is a programmer's best friend. Rails is the definitive full-stack framework built on it. Together, they scale from a weekend prototype to Shopify — without ever getting in your way.

- **Ruby**: released 1995 by Yukihiro "Matz" Matsumoto. Latest: Ruby 4.0.
- **Rails**: released 2004 by DHH / 37signals. Latest: Rails 8.1.3 (March 24, 2026).
- **Doctrine**: optimize for programmer happiness, convention over configuration, the menu is omakase, no one paradigm, exalt beautiful code, provide sharp knives, value integrated systems, progress over stability, push up a big tent.

## Built on Rails (a partial list)

- **Shopify** — 4M+ stores on a Rails monolith
- **GitHub** — 100M+ developers, 2M+ LOC Rails app
- **Airbnb** — global marketplace scaled on Rails
- **Basecamp** — where Rails was born
- **GitLab** — open-source DevOps powerhouse
- **Instacart** — real-time logistics for millions
- **Zendesk** — multi-billion-dollar SaaS empire
- **Kickstarter** — crowdfunding the creative world
- **Hulu** — streaming built on Rails
- **Coinbase** — high-traffic crypto exchange
- **Gusto** — billions in payroll processed
- **SoundCloud** — one of the world's largest audio libraries

## Why Ruby

1. **Optimized for happiness.** Ruby was designed with one goal: make programming a joy. Every syntax choice bends toward the human, not the machine.
2. **Expressive and concise.** Where other languages need a paragraph, Ruby needs a line. Blocks, symbols, and open classes let intent lead the code.
3. **200,000+ gems, 30 years strong.** A mature ecosystem battle-tested since 1995.

## Why Rails

1. **Convention over Configuration.** Sensible defaults; skip the boilerplate.
2. **The One-Person Framework.** ORM, routing, jobs, mailers, storage, credentials — batteries included.
3. **Hotwire & Turbo.** Reactive UIs backed by server-rendered HTML.
4. **Scales from PROMPT to IPO.** Rails 8 ships with Solid Queue, Solid Cache, and Kamal.

## Code, side by side

The Rails way:

```ruby
# app/controllers/products_controller.rb
class ProductsController < ApplicationController
  def index
    @products = Product.published
  end
end
```

The verbose alternative:

```java
public class ProductsController {
  @Autowired
  private ProductRepository repo;

  @GetMapping("/products")
  public ResponseEntity<List<Product>> index() {
    List<Product> products = repo.findAllByPublishedTrue();
    return ResponseEntity.ok(products);
  }
}
```

> "Ruby is simple in appearance, but is very complex inside — just like our human body." — Yukihiro Matsumoto

## Common objections, answered

- **Ruby is too slow.** Performance is almost never a language problem. Shopify serves millions of requests per minute on Rails. Ruby 4's ZJIT closes the gap further.
- **Rails hiring is hard.** Rails attracts senior engineers who care about craft. Tight pool of high-signal talent beats a huge pool of framework tourists.
- **Rails is dead.** Rails 8 shipped in 2026 with Solid Queue, Solid Cache, Kamal, and a doctrine built for AI-agent-authored code. Rails World 2026 sold out.
