Kotlin roadmap

Last modified on	February 2025
Next update	August 2025

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: more efficient data handling, increased abstraction, enhanced performance with clear code.
Kotlin Multiplatform: release direct Kotlin to Swift Export, streamlined build setup, and simplified creation of multiplatform libraries.
Experience of third-party ecosystem authors: simplified development and publication process for Kotlin libraries, tools, and frameworks.

Kotlin roadmap by subsystem

If you have any questions or feedback about the roadmap or the items on it, feel free to post them to YouTrack tickets or in the #kotlin-roadmap channel of Kotlin Slack (request an invite).

Subsystem	In focus now
Language	See the full list of Kotlin language features and proposals or follow the YouTrack issue for upcoming language features
Compiler	🆕 Finalize JSpecify support 🆕 Deprecate K1 compiler 🆕 Promote Kotlin/Wasm (`wasm-js` target) to Beta Kotlin/Wasm: Switch `wasm-wasi` target of libraries to WASI Preview 2 Kotlin/Wasm: Support Component Model
Multiplatform	The first public release of Swift Export Enable Concurrent Mark and Sweep (CMS) GC by default Stabilize klib cross-compilation on different platforms Implement the next generation distribution format of multiplatform libraries Support declaring Kotlin Multiplatform dependencies at project-level Unify inline semantics between all Kotlin targets Enable incremental compilation of klib artifacts by default Kotlin Multiplatform development roadmap
Tooling	🆕 Improve development experience for Kotlin/Wasm projects in IntelliJ IDEA 🆕 Improve performance of imports 🆕 Support resources in XCFrameworks 🆕 Kotlin Notebook: Smoother access and improved experience IntelliJ IDEA K2 mode complete release Design the Build Tools API Kotlin Ecosystem Plugin supporting Declarative Gradle Support Gradle project isolation Improve integration of Kotlin/Native toolchain into Gradle Improve Kotlin build reports Expose stable compiler arguments in Gradle DSL Improve Kotlin scripting and experience with `.gradle.kts`
Library ecosystem	Library ecosystem roadmap items: Refine the Dokka HTML output UI Introduce default warnings/errors for Kotlin functions that return non-unit values that are unused New multiplatform API for the standard library: Support for Unicode and codepoints Stabilize the `kotlinx-io` library Improve Kotlin distribution UX: add code coverage and binary compatibility validation Promote `kotlinx-datetime` to Beta Ktor: 🆕 Add gRPC support to Ktor with a generator plugin and tutorial 🆕 Make project structuring for the backend applications simple 🆕 Publish CLI generator to SNAP 🆕 Create Kubernetes Generator Plugin 🆕 Make Dependency Injection Usage Simple 🆕 HTTP/3 Support Exposed: 🆕 Release 1.0.0 🆕 Add R2DBC Support
