Submit Now! I'm Attending! June 12, 2026 June 13, 2026 Baltic Ruby 2026 UTC Baltic Ruby is a conference that travels through the Ruby community — helping it gain more energy, more inspiration, and more resources to grow and support local Rubyists. In 2026, we’re heading to Hamburg to join forces with Ruby Unconf and create a one-of-a-kind event that blends two worlds: a traditional curated lineup of CFP-selected talks, and an unconference format where anyone can step up and become a speaker on the spot. This Call for Papers is for the main lineup. We’re planning to feature 10 to 13 talks across two days. In past years, we’ve welcomed speakers like Matz, Tim Riley, Marco Roth, and many other respected contributors and voices from the Ruby world. But not only them. We’ve always put special emphasis on diversity — and proudly made space for new voices. Around 50% of our speakers typically come from local communities or are first-time names on the Ruby stage. The same goes for content. Each year, the lineup has had its own unique flavor — with a tilt toward Ruby, frameworks, open source, or something else entirely. But there’s always room for fresh, relevant, and exciting ideas beyond any one narrow theme. This year is no different. We’d love to see a variety of talks that reflect where the industry is heading. That said, in 2026 we’re giving special attention to Rails — so if that’s your jam, you’re extra welcome! So — welcome to Baltic Ruby. There’s space for every kind of talk here, and every submission will be reviewed by our program committee — made up of Ruby community and conference organizers from across Europe. Hamburg

If you have something genuinely useful or interesting to share, we’d love to have you as a speaker. --- ### Sales pitches It’s totally fine to highlight your product, framework, or service. But straight-up sales pitches—especially reused ones—won’t make the cut. --- ### Inclusivity We welcome speakers from every background and experience level. If you’d like to speak but need support or accommodations, let us know. We’ll do what we can to help. --- ### Be nice! We won’t publish anything offensive or disrespectful. We’re here to learn, share, and have fun, let’s keep it that way. Online
