JetBrains has released an official Kotlin extension for Visual Studio Code in Alpha, announced at KotlinConf 2026. The extension connects VS Code to the Kotlin Language Server, which is built on IntelliJ IDEA's code-insight infrastructure. It provides core editor features including code completion, diagnostics, navigation, quick fixes, formatting, and project import. IntelliJ IDEA and Android Studio remain the most complete Kotlin environments, but this extension targets developers who prefer or already use VS Code. The release is part of a broader tooling effort that also includes a Java-to-Kotlin Converter extension for VS Code. The Kotlin Language Server can also be used manually with other LSP-compatible editors that support pull-based diagnostics. JetBrains is seeking community feedback via GitHub.

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

<p>A friend of mine works as a maintenance dev for the tax authorities. He’s been a  Kotlin skeptic so far because of the JetBrains lock-in. I kind of feel him: he is _so _tired of rewriting abandonware Scala and Groovy apps to Spring/Java, and for all he knows the same will happen to Kotlin if JetBrains abandons it. Good to see wider community support being embraced by JetBrains here!</p>
