Scala Days 2026: Call for proposals open

Scala Days 2026: Call for proposals open

Submit your talk https://cfp.scaladays.org/scala26/cfp and be part of Scala Days 2026!

The Call for Proposals is now open and will close on May 31, 2026, at 23:59 CEST.

The Program Committee is looking for talks, labs, and workshops that showcase how Scala is evolving and delivering value in today’s fast-changing technology landscape.

In particular, we’re excited to hear practical insights, real-world experience reports, and forward-looking ideas.

See the topics below for inspiration.

Kind reminder: Super Early Bird tickets are available only until the end of the day on April 30, 2026.

Formats

This year’s program includes three submission formats. Talks and Interactive labs are part of the main conference program, while Workshops take place after the conference and require a separate ticket.

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.
