IntelliJ IDEA Goes LSP: Java and Kotlin Intelligence Comes to VS Code, Cursor, and Agentic Flows
↗
JetBrains is releasing a preview VS Code extension that exposes IntelliJ IDEA's Java and Kotlin language intelligence via the Language Server Protocol, making it available in non-JetBrains editors and agentic workflows.
Developers working in VS Code, Cursor, or terminal-based AI agents can now access IntelliJ's code analysis, completion, and refactoring capabilities for Java and Kotlin without leaving their preferred environment. The extension requires an IntelliJ IDEA Ultimate subscription after the preview period, meaning teams must weigh the licensing cost against the benefit of using IntelliJ's analysis engine outside the IntelliJ IDE.
