Extism is a cross-language framework for building with WebAssembly that functions as an off-the-shelf plug-in system you can integrate as a library. It emphasizes security by sandboxing all plug-in code, enabling safe execution within your host app and fast deployment (ship in days, not weeks). It offers SDKs for many languages (Python, Node, Ruby, Rust, Go, PHP, C/C++, OCaml, and more) and is designed to run almost anywhere.
