Two weeks ago, some of our Lisbon team headed north to Viana do Castelo for Euruko 2025, Europe’s biggest Ruby conference. It was an inspiring few days packed with talks, workshops, and plenty of hallway conversations with Rubyists from all around the world.
Euruko is known for its welcoming, community-driven atmosphere, and it brought together expert developers to share knowledge, swap stories, and explore the future of Ruby.
Euruko always balances technical depth with community spirit, and this year was no different. For us, it was more than just attending talks. It was about immersing ourselves in the Ruby ecosystem, meeting peers, and bringing back ideas we can apply directly to our work. Here are some of the highlights and key themes we’re taking away from this year’s event:
1. The Ruby Ecosystem Keeps Evolving
Talks this year emphasised how Ruby is improving performance, concurrency, and developer experience, all while keeping its trademark elegance. We’re excited to test out new Ruby features on internal projects to see how they can boost both scalability and productivity.
2. The Rise of AI + Ruby Workflows
AI was a recurring theme, with many speakers showing how Ruby developers can integrate AI into testing, reviews, and building smarter applications. Without a doubt, we’ll be experimenting with AI-driven tooling in our own workflows, from test automation to documentation support.
3. Better Developer Experience with Herb
Marco Roth’s talk on Herb stood out for us. Herb is an HTML-aware ERB parser that brings modern, fast, and fault-tolerant tooling into Rails views. With a built-in CLI, language server, formatter, and linter, it transforms everyday .html.erb work into something far smoother.
As Darren from our team put it: “Definitely a game-changer for Rails developers looking to level up their DX.”
4. Simplifying AI Integration with RubyLLM
Carmine Paolino introduced RubyLLM, which tackles a big pain point: every AI provider ships their own bloated client, with different APIs and conventions.
RubyLLM solves this by offering one unified API for all providers (like GPT, Claude, or even local Ollama) with just three dependencies: Faraday, Zeitwerk, and Marcel. This is a big step toward cleaner, more maintainable AI integrations in Ruby, and we’re eager to test it out.
5. Ruby Gems, Live in the Browser
Albert Pazderin impressed the audience with a demo of Ruby + WebAssembly. His talk explored how WebAssembly can power interactive Ruby gem tutorials that run right in the browser. No installs, no repo clones, no config headaches.
We see big potential for this in onboarding and training. Interactive docs and browser-based tutorials could lower barriers for newcomers and speed up experimentation for seasoned devs.
6. Community & Continuous Learning
Beyond the talks, Euruko was a reminder of why we invest in events like this: to learn, share, and grow together as a team. Each of us came away with different insights, and we’ll be running internal workshops to spread that learning across the company.
Wrapping Up
Attending Euruko 2025 reinforced our belief that investing in learning isn’t just good for individual growth, it’s good for our clients and partners, too. By staying close to where Ruby (and the broader tech ecosystem) is heading, we can continue delivering work that’s forward-thinking, reliable, and impactful.
A huge thank you to the Euruko organisers, the inspiring speakers, and everyone we met along the way. We’re already looking forward to Euruko 2026!
