Hexana — IntelliJ Plugin Documentation

Hexana is an IntelliJ Platform plugin (plugin ID org.jetbrains.hexana, vendor JetBrains) for WebAssembly and binary analysis. It parses .wasm modules, renders WAT and WIT, opens native binaries (ELF, Mach-O, PE) and JVM artifacts (.class, .jar, .war, .apk, .jit), integrates with WASM runtimes (Wasmtime, WAMR, GraalVM), exposes a Model Context Protocol (MCP) server for AI-assisted exploration, and ships Java-side code completion for the GraalWasm and Chicory APIs.

Version and compatibility

  • Plugin version: 0.10.
  • since-build: defined by gradle.properties → defaultSinceBuild. Hexana targets IntelliJ Platform 2024.1+.
  • Optional integrations: the JavaScript plugin (enables JS interop for instance.exports) and the Java module (enables GraalWasm / Chicory completion). Both are loaded when the host IDE bundles them.
  • Required dependency: com.intellij.mcpServer — Hexana registers its toolset against the platform MCP server.

Supported IDEs

IntelliJ IDEA, RustRover, WebStorm, CLion, PyCharm, Rider, PhpStorm, and any other IDE on IntelliJ Platform 2024.1+ that bundles or installs com.intellij.mcpServer. RustRover and CLion users get the natural fit for binary tooling; WebStorm and PhpStorm users get JS interop.

A companion VS Code extension is published separately on marketplace.visualstudio.com and open-vsx.org. See the VS Code section of this site for that product's documentation.
