Experimental Kotlin Language Server for VS Code

A pre-alpha, official Kotlin Language Server is now available for Visual Studio Code, implementing the Language Server Protocol for Kotlin. Built upon IntelliJ IDEA and its Kotlin plugin, this server supports most essential features but is experimental and lacks stability guarantees. Currently, only JVM-only Kotlin Gradle projects are supported out-of-the-box. Parts of the implementation are currently closed-source for faster development, with plans for full open-sourcing later. While easily installable as a VS Code extension, other editors require manual configuration. Users are encouraged to try it and provide feedback, but direct code contributions are not yet supported.
