Our Program Committee welcomes you to the Scala Days 2026 Call for proposals, open April 30 - May 31, 23h59 CEST

Join us for the 17th edition of Scala Days by giving a presentation during the conference on October 12-13, 2026.

We are bringing a diverse community to Berlin to share and explore all the latest in Scala, functional programming, and software engineering. As part of making a great program, we (the Program Committee) look to provide up-to-date and practical knowledge on Scala and surrounding technologies for software developers, software architects, team leads, community members, and researchers. We are particularly interested in practical insights and experience reports that demonstrate how Scala continues to evolve and deliver value in rapidly changing technological landscapes.

Whether you’re a seasoned expert or a first-time speaker, we encourage you to submit your ideas and help shape this year’s program. Seize this chance and contribute to the Scala community!

Formats

Talks (30 minutes)

Classic conference talks for sharing ideas, lessons learned, technical deep-dives, and real-world experience.

We’re looking for talks that bring real value to the community: practical insights, innovative approaches, hard-earned lessons, or fresh perspectives on Scala and its ecosystem.

We will select up to 48 talks, organized across 3 parallel tracks as part of the main conference program.

Interactive Labs (2 hours)

Interactive labs are a new format at Scala Days 2026: small-group, highly interactive sessions built around live demos, guided exploration, and practical experimentation during the conference.

This format is ideal for showcasing tools, libraries, frameworks, and new ideas in action. The goal is for participants to explore, experiment, and leave with practical experience they can immediately apply.

Because sessions are limited to 2 hours total, proposals should be designed to get participants engaged quickly, with minimal setup time and a clear path into the core experience.

Interactive labs are also a great fit for open-source maintainers who want to introduce their projects, onboard new users, and grow their contributor community.

We will host up to 16 Interactive labs, organized into two dedicated conference time slots, across both days.
Each session is limited to 10 participants, with seats allocated on a first-come, first-served basis.

Workshops (2 days)

Workshops are in-depth training sessions held after the main conference, on October 14–15.

Unlike Talks and Interactive labs, Workshops require a separate ticket and provide dedicated time for deeper exploration of a topic through practical exercises, discussion, and guided learning.

They are designed to equip participants with substantial knowledge and practical experience over the course of two full days.
