Kotlin roadmap

Last modified on	August 2026
Next update	February 2027

Welcome to the Kotlin roadmap! Get a sneak peek into the priorities of the JetBrains team.

Key priorities

The goal of this roadmap is to give you the big picture. Here's a list of our key focus areas – the most important directions we are focused on delivering:

Language evolution: keep Kotlin concise and expressive, prioritizing ergonomics and safety over ceremony.
Kotlin Multiplatform: become the foundation for modern cross-platform apps through a solid iOS experience, mature web targets, and reliable IDE tooling.
Staying agnostic: support developers no matter their tools or targets.
Experience of third-party ecosystem authors: simplify the development and publication process for Kotlin libraries, tools, and frameworks.
