It mattered because it gave editor-agnostic Kotlin completion, diagnostics, hover, symbols, and navigation before JetBrains published an official Kotlin language server. ### Project history The GitHub repository was created on 2018-05-28 and early release metadata shows version 0.1.3 on 2018-06-12. The README describes a language server providing smart completion, diagnostics, hover, document symbols, definition lookup, and signature help for Kotlin in any LSP-capable editor. The README explicitly notes that JetBrains later published an official language server and that this community project can be considered deprecated. JetBrains documentation describes the official Kotlin Language Server as based on IntelliJ IDEA, the IntelliJ IDEA Kotlin plugin, JetBrains AIR, and Fleet. ### Adoption history The project became widely referenced because Kotlin users outside IntelliJ IDEA and Android Studio needed LSP support in editors such as VS Code, Atom, Vim/Neovim, Emacs, and Helix. Package-manager adoption in Homebrew, MacPorts, Nix, and APK reflects that cross-editor audience. GitHub repository metadata observed on 2026-07-01 reported 2,035 stars and 249 forks, a notable footprint for a language server maintained outside the language vendor. ### How it is used Users install the `kotlin-language-server` executable and configure an LSP client in their editor. For classpaths, the README documents automatic Maven or Gradle resolution as well as manual scripts such as `[project root]/kls-classpath` or config-root `kotlin-language-server/classpath` files. Its practical use was strongest for Kotlin/JVM projects where editor users wanted language intelligence without opening the project in IntelliJ IDEA. ### Why package nerds care This package is significant because language servers are exactly the kind of tool package managers make useful: one executable can unlock editor integrations across many frontends. It also captures a transitional moment in language tooling, where community LSP implementations filled gaps until language vendors shipped official servers. ### Timeline - 2018-05-28: GitHub repository created. - 2018-06-12: 0.1.3 release published in GitHub release metadata. - 2019-08-16: 0.3.0 release published. - 2019-10-25: 0.4.0 release published. - 2025: JetBrains documentation published an official Kotlin Language Server page, and the community README marked fwcd/kotlin-language-server deprecated in favor of it. ### Related projects - The project is related to the Language Server Protocol, Kotlin compiler internals, editor LSP clients, VS Code Kotlin integrations, and JetBrains' official Kotlin Language Server. - It also sits near kotlin-debug-adapter and tree-sitter-kotlin, both of which appear in the README as companion editor-agnostic Kotlin tooling. ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
