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

Key priorities

The goal of this roadmap is to give you a big picture. Here’s a list of our key priorities – the areas we are investing the most effort into:

  • Fast turnaround: making the change-test-debug cycle really fast.

  • New compiler: a rewrite of the Kotlin compiler optimized for speed, parallelism, and unification. Later we will also work on pluggability.

  • Fast and smooth IDE: improving the stability and performance of the Kotlin IDE.

  • Kotlin for JVM server-side development: expanding support for server-side use cases across the Kotlin ecosystem.

  • Kotlin Multiplatform Mobile: improving the user experience and feature set for sharing code on mobile platforms.
