About Scala Days

Spirit of Scala Days 2025

Scala Days brings developers from around the globe to share their experiences and new ideas around creating applications with Scala and related technologies, like Spark, Kafka, and Akka. Scala Days provides a unique opportunity for Scala users to interact with the contributors to the language and related technologies and connect with fellow developers.

Leaders from Scala User Groups and global communities, students, and language contributors will gather to discuss academic research, use cases, and visionary projects for a two-day, action-packed event.
