Beyond `flatMap`: Is Kyo the Future of Scala Effects?

About This Talk

For nearly a decade, Scala's concurrency has been driven by Akka, Cats Effect and ZIO, each with its own vision for purity, safety, and pragmatism.

Kyo enters this incredible ecosystem with a fresh perspective.

This talk provides a critical, technical comparison of these systems through a unified framework, evaluating their approaches to:

- Effect Modeling: How they represent, compose, and handle effects and errors.

- Concurrency & Resilience: The guarantees and costs of their fiber and structured concurrency models.

- Developer Experience: The trade-offs in readability, ergonomics, and type-driven safety.

We will focus on how Kyo’s use of algebraic complements the work of its predecessors.

You'll see how it embraces Scala 3 and understand why it earns its place in an already fantastic field.
