🖼️ Introducing On Rails: A New Podcast 🎙️ from the Rails Foundation

The Rails Foundation wanted to launch a new podcast featuring “Rails devs talking about the nitty gritty technical decisions they’ve made along the way” – now it’s here, hosted by Robby Russell. You can listen to the first episode here featuring 37signals’ Rosa Gutiérrez talking about her team’s work building Solid Queue.

📺 💻 DHH: Future of Programming, AI, Ruby on Rails, Productivity & Parenting | Lex Fridman Podcast

David Heinemeier Hansson (aka DHH) is a legendary programmer, creator of Ruby on Rails, co-owner & CTO of 37signals that created Basecamp, HEY, & ONCE, and is a NYT-best-selling author (with Jason Fried) of 4 books: REWORK, REMOTE, Getting Real, and It Doesn't Have To Be Crazy At Work. He is also a race car driver, including a class-winning performance at the 24 hour Le Mans race.

💻Native integrations for Hotwire Native apps

Planning to build native apps with Rails? You’ll definitely need Bridge Components.

Hotwire Native enables seamless communication between native Swift and Kotlin code and web views in hybrid mobile apps. Bridge components extend this functionality by providing reusable native components that interact your web views. They enable developers to break out of the web view container and drive native features.

Add production-ready bridge components to your app without writing any custom Swift or Kotlin.

You can also get access to advanced components and priority support: pro components

💻 How large companies build architecture: solutions, technologies, approaches

📦 Version control and API management

They use Garage Extension — an extension to the monolith (Rails), configured separately via a client.
Required: Rails / Sinatra, gRPC / JSON API, CI/CD (e.g., GitHub Actions, CircleCI)

🔗 Microservice communication

Challenge: requests between many services → complexity, latency, fault tolerance.
Solution: GenExpediter — a Ruby equivalent of Netflix Hystrix.

Required: concurrent-ruby, Redis / Kafka / RabbitMQ for queues, Sidekiq / Resque, Circuit breaker + fallback logic, Monitoring: Prometheus + Grafana

🏗 Lego-style architecture approach
Rails is minimalist but flexible. Want a monolith — keep it. Want microservices — add them.

Options: Dry-rb — clean architecture, Hanami — for stricter structure, Event Sourcing via RailsEventStore, gRPC / JSON-RPC for inter-service communication

📺Rails New with typecraft

💻 Exactly 21 years ago, DHH introduced the world to the first version of Rails — v0.5.0 — with the words: "this piece will grow in public."

He wasn’t wrong.

Since then, Ruby on Rails has become the foundation for thousands of companies around the world, grown with the support of countless developers, and stayed true to its core principles: simplicity, elegance, and productivity.

Rails 0.5.0 marked the end of vaporware — and the beginning of a new era in web development.

Original announcement from July 24, 2004:

rubytalk.org/t/ann-rails-0-5-0-the-end-of-vaporware/12744/1

Want to build iOS and Android apps without leaving Rails?

At RailsConf 2025, Joe Masilotti showed how Hotwire Native lets you create native mobile apps using just HTML, CSS, and Rails.

One codebase — three platforms: Web, iOS, Android

Instant updates across all platforms

📺Watch the talk on YouTube

Only 31% of Rails developers use Stimulus, while the majority believes that Rails API + SPA architecture is “necessary.”
Inertia.js allows to build modern JS components without the SPA complexity:

- A step-by-step tutorial to add Sign Up to your e-commerce app

- A brand new video series with Typecraft (don’t miss this!)

-A centralized Tutorials Hub to bring it all together

📺Hotwire Native Modals

Hotwire Native modals… when to go web vs. when to go native?

Learn how to turn off your JavaScript and HTML modals when rendering in the iOS and Android apps. This helps create a better native experience by making the app feel more, well, native!

💻 70 Companies You Didn't Know Were Using Rails in 2025

Duolingo, Netflix, Spotify, Peloton, Robinhood... all running Rails under the hood. From edtech to finance, Rails is quietly powering systems at global scale.

💻Turbo PR #1427 by Rosa Gutiérrez: the first step toward full offline support in Turbo using service workers

New @hotwired/turbo/offline package + strategies: networkFirst, cacheFirst, staleWhileRevalidate.
Useful for PWAs and mobile apps built with Hotwire Native.
