Official Kotlin Support for Visual Studio Code Is Now Available in Alpha | The Kotlin Blog

Announced at KotlinConf 2026, the Alpha release of the official Kotlin extension for Visual Studio Code is now available, offering Kotlin developers an alternative to IntelliJ IDEA and Android Studio for their coding environment. The Kotlin by JetBrains extension integrates with the Kotlin Language Server, providing essential features such as code completion, diagnostics, navigation, quick fixes, and formatting, all backed by IntelliJ IDEA's code-insight infrastructure. This release is part of JetBrains' broader effort to enhance Kotlin tooling across different platforms, following the earlier introduction of a Java to Kotlin Converter extension. As an Alpha release, user feedback is crucial to refine the extension, and developers are encouraged to share their experiences and report issues on GitHub.
