Extism: a WASM-Powered Plugin System
summary
Extism is a WASM-powered plugin system that loads WebAssembly modules with a PDK and currently supports eight languages; hosts invoke plugin-exported functions or expose host functions for plugins to call. Communication runs through separate memory spaces, so payloads must serialize (JSON recommended) and primitive types pass directly. Example integration targets include a desktop GitKraken client, CLI, and VS Code/JetBrains plugins so a single plugin could work across those apps. Extism is Rust BSD-licensed and relies on runtimes like Wasmtime; discoverability and a hosted marketplace remain necessary.
