First: The Rails World website is finally live thanks to our website sponsor WyeWorks, and the amazing work of developers Jessica Ferreira and Lucas Troncoso and designer Jomiro Eming. Big thanks to the team!

Check it out.

Apply to speak at Rails World 2026

Most of all, we’re excited to announce that the CFP for Rails World 2026 is officially open.

Submit your talk by May 16: https://sessionize.com/rails-world-2026/

What we’re looking for in 2026 (you’ll never guess)

Rails has always been about developer happiness, productivity, and the ability to build ambitious things with small teams. That hasn’t changed, but the landscape around us has. AI-assisted development is mainstream, teams are getting smaller, iteration cycles are getting shorter, and the ability to move quickly matters more than ever. And Rails is well positioned for all of this.

Some of our CFP themes remain the same as previous years (Rails 8 in production, The competitive advantage of Rails, Focus on the frontend), but this year, we’re adding a few new themes that reflects how modern application development and workflows are changing:

• AI-native development with Rails
• Rails + AI / Agentic Systems
• Trust, Security, and Reliability

In short: we really want to hear how you’re building now, not just what you’ve built.

Check out the CFP for more details about those and other themes, speaker benefits, and how to apply.

The CFP and speaker benefits are made possible thanks to our Speaker Support sponsor, Beyond Finance.

New for 2026: Workshops…maybe.

If all goes well, we hope to offer workshops this year on Sept 22. 🤞🏻

Workshops need to be hands-on, teachable in 4 hours or less, and leave people with something concrete to take away.

While we are open to all topics from the CFP, we would strongly consider workshops with topics that attendees have asked for before:

• AI-Native Development with Rails
• Rails + AI / Agentic Systems
• Focus on the frontend

If you’ve ever wanted more time than a standard 30-min talk allows, and have a hands-on, longer-form session in mind (and you have, because you’ve asked me), this is your chance.

Apply via the CFP by May 16. Workshops priced and announced in June.

Rails at Scale returns

The Rails at Scale Summit will return the day before Rails World as a separate, invite-only event where engineers working on high-performance, high-traffic systems can connect and exchange insights, best practices, and hard-earned lessons.

We encourage applications from anyone working with Rails at scale. However, this is an invite-only event capped at 150 attendees, so space is limited.

Applicants are asked to apply to attend or speak by May 8. We will review all applications and suggested talks and select those who best align with the event’s focus (undoubtedly AI will play a large role at the summit, too).

Apply to attend the Rails at Scale Summit here.

Corporate Support tickets are live

We’ve released Corporate Support tickets for $1,300. These pre-released tickets cover almost the full cost of having an attendee at Rails World (no joke), and are ideal if your company wants to send your team and can use an L&D budget.

Support tickets play a key role in making Rails World possible and also help keep General Admission tickets affordable for community members paying out of pocket. As a thank you for supporting the event, we’ll recognize your name (or your company’s name) during the opening session at Rails World.

We also have a very special limited edition swag item for Corporate Support ticket holders that I promise you haven’t seen before. I’m so excited about it.

Support tickets are already available. Book yours here.

General Admission tickets are coming

General admission tickets will go on sale on May 12th at 10 am Central Time, and will be priced at $699. The general admission tickets are greatly subsidised by the Rails Foundation and Rails World sponsors, and they tend to sell out quickly.

But we do have more tickets available this year, so I am always hopeful!

Don’t forget to sign up to the event mailing list to receive a reminder on the day itself.

That’s all for now. Good luck to all who apply!

Rails Foundation

Still here? Great. Interested in sponsoring?

There are still a few booths and programs remaining, and a few fun ideas we are trying to get off the ground. Check out the 2026 prospectus and get in touch at sponsors@rubyonrails.org to join our amazing lineup of sponsors this year.

Founded in 2005 and headquartered in Carlsbad, CA (with a fully remote team), Planning Center builds church management software used by more than 90,000 churches around the world. Their platform helps churches organize the practical details of ministry - service planning, volunteer scheduling, donations, event registrations, check-ins, small groups, and more.

On Rails since day one

If it runs at Planning Center, it runs on Rails, and has for nearly two decades. That includes:

• Customer-facing web applications used daily by tens of thousands of churches
• API backends for their mobile apps and public developer API
• Church Center, their congregation-facing web experience
• Internal tools, account management, and billing systems

The platform consists of multiple Rails applications, where each core product (Services, People, Groups, Giving, Registrations, Calendar, Check-Ins, Publishing, and more) runs as its own Rails app. In a world of majestic monoliths and sprawling microservices, Planning Center took another path: macroservices. (Internally, they call it the “Stonehenge architecture.” Nobody quite remembers why it was made that way, but it works, and people keep coming back to see it.)

Bootstrapped and profitable since day one, Planning Center has now grown to a team of 225 people, more than 100 of whom are engineers. The company has no outside investors, no debt, and no plans to sell. In fact, they recently committed to transitioning to a non-profit structure, reinforcing their long-term commitment to serving churches rather than building equity.

Joining the Rails Foundation

Founder Jeff Berg has long been a member of the community, and was even in attendance at the first RailsConf back in 2006.

Rails is not just our framework, it’s the foundation our entire company grew up on. Every product, every API, every line of code that serves all churches runs on Rails. Joining the Rails Foundation felt less like a strategic decision and more like finally showing up to the family reunion.

Jeff Berg CEO, CTO, & Founder, Planning Center

Planning Center’s history of building, scaling, and sustaining a profitable, independent company on Rails is yet another testament to what the framework makes possible. We’re excited to have them on board, and we appreciate their support of our shared mission.

Welcome to the Foundation, Planning Center!

Planning Center joins Core members Cookpad, Doximity, Fleetio, GitHub, Intercom, Judge.me, Procore, Shopify, 1Password and 37signals, and Contributing members AppSignal, Cedarcode, Chime, Clio, Fullscript, Gusto, Higher Pixels, makandra, Planet Argon, Renuo, Saeloun, SerpApi, and TableCheck.

Learn more about the Rails Foundation and its mission here. If your company would like to join the list, please reach out to foundation@rubyonrails.org.

Ruby 4.0.0 is days away, the Ruby website and documentation just got awesome new rebrands, and there are constant updates to the Rails framework.

But we’ve also watched this year as companies built on Rails grow and adapt to a new (and constantly shifting) AI landscape in fascinating ways. There are new startups choosing Rails every day, new projects and gems taking shape, new folks joining the community, new conversations, new collaborations, new books being published, new events popping up all over the world.

Things are happening, left, right and center, and at times the pace feels breathless. You all just…don’t stop shipping.

You are building, experimenting, and scaling, and the Rails Foundation is here for it.

Keep running, and we will be there, cheering you all on.

Here’s what kept the Rails Foundation running alongside you in 2025:

We launched a podcast. (Education - Marketing)

On Rails is hosted by Robby Russell and features deep conversation focused on the technical decisions, architectural trade-offs, and long-term thinking behind building and maintaining Ruby on Rails applications. In season one, Robby spoke to Rosa Gutierrez, Jean Boussier, Nadia Odunayo, Ryan Stawarz, Austin Story, Hilary Stohs-Krause, Florent Beaurain, Alexander Stathis, Miguel Conde, Peter Compernolle, Kayla Reopelle, and Jay Tennier. It’s a wonder he still has a voice.

On Rails is hosted on Buzzsprout, and edited by Anuschka Laubscher. Find it on all major podcast platforms, and subscribe to be notified when the next episodes drop, because Robby has some great guests lined up for you in 2026.

Work on the Rails Guides continued. (Documentation)

This year, 12 guides were updated and we started work to improve the SEO of the Ruby on Rails website, thanks to the efforts of Ridhwana Khan, Bhumi Shah, Harriet Oughton, Petrik de Heus, the team at Ranker Studios, and the many, many folks in the community who helped by reviewing the PRs. Only a few more guides to go before we can wrap this work up in 2026.

We shipped two new tutorials and a new tutorial page. (Education)

When we revamped the Getting Started guide in 2024, we changed the demo app from a blog to an e-commerce site, giving us a better starting point to expand the tutorial over time and allow beginners to continue learning by adding new real-world features to their app. Chris Oliver continued that work this year with two additional tutorials: Sign Up & Settings and User Wishlists. Find them both on the new Tutorial landing page, which also landed this year with help from John Athayde and Naijeria Toweett: rubyonrails.org/docs/tutorials.

We shipped another Rails case study. (Marketing - Documentation)

The newest Rails case study in the series highlights how and why Cookpad migrated to Rails in 2007. Find it here.

This case study was a collaborative effort made possible by Miles Woodroffe from Cookpad, Robby Russell from Planet Argon, the Cookpad engineering leadership team, and John Athayde from Meticulous.

A lot of work across a number of teams goes into these case studies, and while they are not fast and easy to write, these stories help demonstrate the decision-making behind choosing Rails, and the real-world impact of Rails across different industries and organizations of all sizes. We’ll have another one coming in 2026, so stay tuned.

We supported regional Rails events. (Events)

This year we sponsored Rails Girls São Paulo (Brazil) and Rails Girls Cali (Colombia), and partnered with Tropical on Rails to make sure there were a batch of sponsored tickets set aside for local devs who might not have been able to get a ticket otherwise.

All three are events run by teams doing fantastic work to promote Rails in South America, and we were happy to support their efforts this year.

We put a lot of focus on video this year. (Education - Marketing)

The Rails YouTube channel is growing and the content is expanding. This year we published the Rails New series with Typecraft, we continued the Rails in Focus series with three new videos, and we started experimenting with YouTube shorts.

We also started recording a new series with Rails maintainers and community members about what Rails is - the people who make it, the rules that guide it, and the community that uses it. Expect the pilot episode to drop in January.

Big shout out to Chris Power, Robert Beene, Harriet Oughton, Emmanuel Hayford, Carolina Cabral, and Anuschka Laubscher on the work that went into preparing, recording, and editing these different series.

We produced the third Rails World and launched the Rails at Scale Summit. (Events - Marketing - Education - Community)

This year we returned to Amsterdam where 825 attendees joined us for the third Rails World and the very first Rails at Scale Summit.

Rails World is our flagship annual event, where more than a year of preparation culminates into a whirlwind week of making sure all attendees, speakers, and sponsors have the best combined experience. We had a lot of fun this year, and we hope you did too.

Read the Rails World 2025 recap here, in case you missed it. A big, final thank you to this year’s production and volunteer teams, as well as a shout out to Jomiro Eming, Gaia Putrino, Inez Alvergne, Amani Jones, Beatriz Mitre, Theodora Ntoka, and Bram Janssen for their help on the event.

Marco Roth won the 2025 Rails Luminary award. (Community)

And finally, as one of the last orders of business this year, the Rails Core team and the Rails Foundation announced Marco Roth as the Rails Luminary for 2025 for his unique vision and work on improving the Rails view layer.

Core member Xavier Noria traveled to Zurich to announce the news to Marco during the Rails Höck meetup at the Renuo offices in person (video here).

The Rails Foundation continues to grow.

All of the work that listed above is thanks to the ongoing support of our members who show up time and time again for the Ruby community in a multitude of ways.

This year that number grew by seven more companies.

Judge.me joined the Core members of the Rails Foundation, with co-founder and Chief Architect Linh Dam joining the board. The board also welcomed new directors Whitney Imura (GitHub) and Gabi Stefanini (Shopify), and we’d like to extend a sincere thank you to Neha Batra and Duncan Davidson, who previously served as directors, for their time and contributions while on the board.

And finally, we welcomed Saeloun, Clio, Higher Pixels, Chime, Fullscript, and SerpApi as Contributing members this year.

So, what’s up next in 2026?

All of the efforts above will continue, and we are deep in 2026 planning right now with even more ideas on how to further our mission. But for now, here’s what we know for sure is coming (and where we are looking for help):

• Rails World 2026 and the Rails at Scale Summit will take place in September in Austin. Read some preliminary information here, and if your company wants to support, you can find the sponsorship prospectus here.
• Brazil, India, and Japan are home to some of the most active Rails communities in the world. While it would be exciting to host a Rails World in each of these regions, we believe the most meaningful way to support Rails globally is by partnering with local organizers who understand their communities, cultures, and local Rails ecosystems best. So this year, the Rails Foundation is proud to support Tropical on Rails in Brazil, Deccan Queen on Rails - a new event coming to Pune, India, and Kaigi on Rails in Japan.
• Due to a change on the documentation team, we are looking for one more writer to join and help us finalize the work in 2026. If you have experience writing technical documentation and are available for approximately 10 hours a week in 2026, please get in touch.
• We are also looking specifically for someone to write an Accessibility guide for Rails apps. We have an outline started, but would prefer someone with direct experience to help write this new guide. If that’s you, please get in touch for a chat.

Stay tuned for all of that and more in 2026. As always, our suggestion box is open.

That’s a wrap on 2025.

For now, here’s wishing everyone in the Rails community a fantastic end to 2025!

Rails Foundation

The Rails Luminary Awards exist to celebrate those in the community who have significantly advanced Rails for the benefit of all, through contributions, gems, ideas, or knowledge-sharing, and Marco ticked all of those boxes this year.

From Rails Core member Xavier Noria:

Marco has been a prolific Open Source author for many years, and is now doing outstanding work on Herb, ReActionView, and his vision for improving the tooling and user experience around the Rails view layer. He travels the world sharing his work and knowledge at conferences and, if you have met him, you know he is as highly skilled as he is humble and kind. Marco embodies everything this award represents: technical excellence, generous collaboration, and a genuine commitment to making Rails better for everyone. We couldn’t be more proud to present him with the Rails Luminary award.

If you haven’t followed Marco’s work, you can catch up by checking out his talks about Herb and ReActionView at three events this year: RubyKaigi, RailsConf, and Rails World.

Through these projects - plus being a genuinely positive, kind guy - Marco has helped inspire the community, and we can’t think of a better person to receive the Rails Luminary award this year.

As part of being a Rails Luminary, Marco received an award and will receive a $1,000 prize.

Thank you to all who nominated community members this year, and congratulations Marco. Thanks for all your work.

A few quotes from the nominations:

Marco Roth deserves recognition because he’s genuinely made Rails more fun and easier to work with. Thanks to things like Herb, building interactive UI in Rails suddenly feels lightweight and natural, and his work on Turbo Morphing solved a bunch of real-world frustrations people hit when using Hotwire every day. What I appreciate most is that Marco doesn’t just release code — he explains things, shares ideas, helps others, and pushes the ecosystem forward in a friendly, down-to-earth way. A lot of us build better Rails apps today because of the tools and patterns he’s brought to the community.

Marco’s been doing incredible work for Rails with Herb and ReactionView. Views have been a fairly unchanged thing in Rails for years and his work is improving ERB and views enormously. Herb has already found a ton of impossible to spot issues with my views. His Rails World talk got so many people excited and he really deserves credit for all his work on this, Stimulus, Turbo, etc.

Marco has been a huge Open Source ruby contributor, gathered the community together through the ruby events website, and tackled very hard and a bit neglected tooling problems for the front end.

Big shout out to Alessandro Rodi, Josua Schmid, and Yessin Ben Brahim from Renuo, who helped us organize a lastminute Railshöck meetup in Zurich and invited Marco so that we could surprise him with the award in person. Here’s a video of how it went!

Before the year wraps up, while everyone is planning their 2026, we wanted to share some quick information about Rails World 2026 in case that is on your conference wishlist next year (and we hope it is!).

Quick overview

• Dates: September 23 & 24, 2026 (Wed & Thurs)
• Location: Palmer Event Center (very central Austin)
• CFP: open Q2/early spring 2026

Tickets

We adjust Rails World attendance to our chosen venue in each city, and since everything is bigger in Texas, that means we will have space for 1,200 attendees: the largest Rails World yet.

Tickets will be released in Q2 2026. We will have the same ticket tiers as before:

• Corporate Tickets - pre-released; for when your company wants to send your team and you can use an L&D budget, or if you wish to support the event further.
• General Admission Tickets - subsidized heavily by the Rails Foundation and released at a later date.

Ticket cost is determined by a number of factors, not least of all sponsorship sales (more on that below), so we are still narrowing down the 2026 ticket prices. This is our first US event, and it’s generally more expensive to produce in the US, so I do expect a small increase from previous years. However, we’re doing our utmost to keep costs down and ticket prices affordable for those paying out of pocket.

Like in previous years, we will supply letters of invitation for ticket holders who need them. Instructions on how to request one will be sent in the confirmation when you buy your ticket.

Rails at Scale Summit

The Rails at Scale Summit is a day of open discussion about scaling Rails applications where engineers working on high-performance, high-traffic systems connect. Last year was the first edition, and it was a success, so we’re doing it again.

The summit will take place the day before Rails World, on September 22nd, and is a separately ticketed event. It will once again be an invite-only event based on an application, with a separate CFP for Summit talks.

Sponsor Rails World

Sponsorship sales are now open. Join us as a Rails World sponsor to connect with the Rails community, showcase your brand or product, and help shape the future of Rails. We have a lot of fun packages this year, and a lot of ideas that we would love to bring to life.

Becoming a sponsor is also a great way to guarantee tickets for you or your team well in advance, and there are a number of low-lift sponsorships this year that allow you to attend the event if you prefer not to man a booth.

Download the prospectus here, and get in touch if you want to chat: sponsors@rubyonrails.org.

That’s it for now.

We’re excited about Austin, and if you’ve never been…we can’t wait to show you why.

Keep an eye on the website for updates, or sign up to this event-specific mailing list to be kept informed. And you can also always reach out at world@rubyonrails.org, I’d love to hear from you.

✌🏻

Rails Foundation

In this case study, you’ll read how and why Cookpad migrated from ColdFusion to Rails in 2007, and how Rails has supported their growth every day since, from their expansion to many more countries, all the way to their public offering on the Tokyo Stock Exchange.

Read the case study: The Secret Ingredient: How Rails Helps Cookpad Serve 100M+ Home Cooks

A huge thank-you to the Cookpad engineering team for generously sharing their story, and a big shout-out to everyone involved in helping bring this case study to life, including Robby Russell from Planet Argon.

Why we’re sharing these stories

A big part of the Rails Foundation’s mission is to help people discover what you already know - that Rails is one of the best frameworks to build fast, flexible, and scalable applications. There’s no better proof than the real stories of companies like Cookpad. These case studies show how Rails lets teams of all sizes to move quickly and achieve meaningful results, so they can put their energy into what counts: growing the business, serving their users, and implementing new features.

Cookpad and Doximity (previously released) are just two stories - find them both on the Docs landing page, and stay tuned for more coming soon.

Founded in 2017, SerpApi enables developers and companies to scrape search engine results from platforms like Google, Amazon, and others, returning structured data in a clean and easy-to-use JSON format.

We at SerpApi have used Rails since our earliest days. I’m grateful for how easy it is to maintain and improve our product with it. I’m also inspired by how Rails helped make the MVC pattern a global standard in web development.

Illia Zub, Operations Engineer, SerpApi

SerpApi’s API, frontend, and background jobs all run on Ruby on Rails. Their app is a majestic monolith, deployed on a cluster of AWS EC2 instances from their automation scripts from CI.

SerpApi relies on a wide range of gems including Mongoid, Sidekiq, Redis, Puma, Stripe-Rails, Airbrake, AWS SDK, HTTP.rb, Nokogiri, Nokolexbor, and Geokdtree. For frontend development, the team uses ERB, jQuery-Rails, and React-Rails.

SerpApi’s contributions to the Ruby ecosystem extend well beyond their own products. They maintain and support several open-source gems, including:

• nokolexbor – a high-performance HTML5 parser for Ruby
• ethon-impersonate – a fork of Ethon that wraps libcurl-impersonate.
• turbo_tests – a faster, incremental test runner for large Rails codebases
• serpapi-ruby – the official Ruby wrapper for SerpApi’s endpoints
• clauneck – a tool for finding contact information via Google Search Results
• uule_converter – a Ruby library for encoding and decoding Google search UULE parameters
• google-local-results-ai-parser – a gem that extracts structured data from Google Local Search Results using AI-based parsing models

SerpApi is also active in the wider developer community, organizing and sponsoring events such as Riverhacks x NASA Space Apps Challenge, Multimodal Search AI Hackathon, and upcoming sponsorships at IDSW.dev and PyCon Indonesia.

The Rails Foundation looks forward to working with SerpApi on our mission to support the Rails community.

SerpApi joins the growing list of companies supporting the Rails Foundation, including Core members Cookpad, Doximity, Fleetio, GitHub, Intercom, Judge.me, Procore, Shopify, 1Password and 37signals, and Contributing members AppSignal, BigBinary, Cedarcode, Chime, Clio, Fullscript, Gusto, Higher Pixels, makandra, Planet Argon, Renuo, Saeloun, and TableCheck.

Learn more about the Rails Foundation and its mission here. If your company would like to join the list, please reach out to foundation@rubyonrails.org.

But first and more importantly: All the talks are now online! Catch up on ones you missed on the Rails World 2025 YouTube playlist.

Recap

814 Rails devs from 62 countries gathered in Amsterdam for more than two days of the latest news in Rails, technical talks, networking, and a fantastic closing party.

Here’s a quick run down of the highlights:

Keynotes

DHH opened by challenging tech’s obsession with complexity, announcing Rails 8.1 beta and a wave of new features—including Markdown Rendering, Active Job Continuations, Action Text Lexxy, Beamer, Active Record Tenating, and Kamal Geo Proxy. He even booted a fresh Framework laptop, installed Omarchy OS, and launched a Rails app in under six minutes. Watch here.

Joe Masilotti closed day one with a keynote about Hotwire Native, showing how Rails devs can now build web, iOS, and Android apps without duplicating business logic. Watch here.

Day two kicked off with Aaron Patterson, Hiroshi Shibata, and Jean Boussier from the Ruby maintainer team in conversation with Robby Russell, sharing recent work on Ruby, pain points and lessons learned, and what they would like to see for and from the Ruby and Rails ecosystem in the future. Watch here.

And finally, Aaron Patterson wrapped things up by diving into Shopify’s work on Ractors, the new ZJIT compiler, and pro tips for writing JIT-friendly code. Watch here.

Rails at Scale Summit

A brand-new addition, the Rails at Scale Summit (sponsored by Shopify) brought together engineers from 36 companies, all facing similar challenges of running high-performance, high-traffic Rails systems. They met for a one-day, single-track event focused on sharing insights, best practices, and hard-earned lessons from operating Rails at scale.

The summit was intentionally limited to 100 participants to encourage candid, small-group conversations, with a schedule that left plenty of room for informal networking so that attendees could connect with others who might already have solved the problems they were facing.

Feedback was really positive, so we are considering hosting it again.

Fun stuff

After a few years of Rails World, we wanted to add a bit of fun and whimsy to this year’s event. So beyond the talks, Rails World had a few other playful experiences this year.

At the Ruby Embassy, powered by Avo and RubyEvents, attendees navigated tongue-in-cheek bureaucracy to get their Ruby Passports stamped, complete with red tape, diplomatic formality and…a light saber??? (The Ruby Passport and Embassy is a thread that can connect all of the many events in our space, so other event organizers - get in touch for more info!)

The Ruby Phone installation invited attendees to share the love with those who couldn’t be in Amsterdam by recording a video message, leaving a note on the “answering machine,” or striking up a surprise conversation via two connected phones in the Sponsor Lounge.

Rubyness gave attendees a memorable and very-Amsterdam way to get to the event venue: by the Baltic Ruby Bingo Boat. Huntress hosted the Lightning Track where 16 speakers gave short, punchy lightning talks, and Shopify closed things out in style with a party at Amsterdam’s Straat Museum, where music, art, food, and dancing capped off the event.

All in all, it was a fun week and we’re already processing feedback from attendees, speakers, and sponsors on how to make next year even better for you.

Speaking of next year…

Save the date - Rails World 2026 will take place in Austin in late September. More info shared soon. Hope to see you there!

As always, none of this would have been possible without the generous support of Rails World sponsors and Rails Foundation members.

• Platinum Sponsor: AppSignal

-Amanda

But first, some frequently asked questions: Will there be a livestream? Will the talks be recorded? When will the talks be online and where can I find them?

The answer to all of those questions: We will not offer a livestream for Rails World this year. Instead, we post the Opening Keynote quickly within 24 hours, and all of the other talks as they are ready over the following 2 weeks, You can find them all soon on the Rails official YouTube channel.

Now on to the sponsors:

Platinum Sponsor: AppSignal

For the third year in a row, AppSignal is the Rails World Platinum Sponsor. Since 2023 they have been at the very heart of the Rails World, bringing demos, sjoelen, fun, and stroopwafels.

This year they also created an Amsterdam Guide, where you can find interesting activities and places to visit while in Amsterdam, the story of the Rails World venue, the Beurs van Berlage, and practical travel information.

Closing Party & the Rails at Scale Summit: Shopify

As a Gold Sponsor, Shopify will have a booth in the Sponsor Lounge where attendees can connect with their Rails experts, stop by to discuss building and scaling applications at massive scale, get help unblocking tough technical challenges, or learn more about opportunities with Shopify’s engineering team.

Beyond the booth, Shopify is also the proud sponsor and host of the Rails at Scale Summit. This one-day event, held the day before Rails World, will bring together 36 companies to share insights, challenges, and solutions unique to working at scale.

Shopify is further extending its support by sponsoring onsite interviews and post-production. This means that even those who can’t attend in person will be able to follow along throughout the day and catch up on sessions shortly after the conference wraps.

• Typesense – Sponsored the wifi.
• ODDS, Rompslomp, TRMNL, IQ Lab, and AndPad – Generously provided financial assistance that enabled seven attendees to join the conference.

As you can see, bringing Rails World to attendees each year takes a village of sponsors. We simply couldn’t do it without all of these companies, and we can’t wait for you to meet them all onsite next week.

From the beginning, this was a project for the community, not just Rails World. So it’s been fun to see Tropical on Rails and Baltic Ruby also use the app for their events this year. That’s exactly what we hoped for when we made it open source. ❤️

This year, we asked Bram Janssen, a junior developer in the community, to take the lead on upgrading the app in collaboration with Telos Labs, getting it production-ready for this year’s event.

Under the hood, the event app uses a modern, vanilla Rails stack, relying on default features like Hotwire, Solid Queue for background jobs, SQLite3, Import Maps, and Kamal 2 for deployment. It also uses Tailwind CSS for styling, Avo for admin, AppSignal for monitoring, Mailpace for email, and AWS S3 for file storage.

But a lot has changed in Rails since last year’s release: Rails 8 and Hotwire Native were both announced just weeks after the app first shipped. So, it was time for an upgrade.

What’s new for 2025?

Upgraded from Rails 7.2 to Rails 8
The app now runs on the latest version of Rails, benefiting from all the framework improvements and updated defaults launched last year.

Native app support via Hotwire Native
We now have native iOS and Android apps, powered by the same Rails backend. They’re live in the App Store and Google Play, thanks to Hotwire Native.

Coming soon:

• Dark mode (feature in review)
• Offline support (in progress)

And there’s still some work to do before Rails World. If anyone wants to help, check out the Issue board. If there’s a feature or issue you’d like to work on, feel free to jump in.

Thanks to Bram, Telos Labs, Tropical on Rails, and Baltic Ruby for making this such a fun, ongoing community collab.

We’ll be rolling out the upgraded app to Rails World attendees soon, so attendees should check their inboxes tomorrow.
