Extism

The universal plug-in system. Run WebAssembly extensions inside your app. Use idiomatic Host SDKs for Go, Ruby, Python, Node, Rust, C, C++, OCaml & more (others coming soon).

Plug-in development kits (PDK) for plug-in authors supported in Rust, AssemblyScript, Go, C/C++.

Add a flexible, secure, and bLaZiNg FaSt plug-in system to your project. Server, desktop, mobile, web, database -- you name it. Enable users to write and execute safe extensions to your software in 3 easy steps:

1. Import

Import Extism host SDK into your code as a library dependency.

2. Integrate

Identify the place(s) in your code where some arbitrary logic should run (the plug-in!), returning your code some results.

3. Execute

Load WebAssembly modules at any time in your app's lifetime and Extism will execute them in a secure sandbox, fully isolated from your program's memory.
