WasiPy - Python Interpreter for WebAssembly

WasiPy is a Python interpreter that runs in WebAssembly using RustPython, enabling Python code execution in sandboxed environments.

Overview

This project consists of two main components:

• executor: A WebAssembly module that contains the Python interpreter (RustPython)
• server: A Rust server that loads and executes the WebAssembly module to run Python code

Building

1. Build the WebAssembly Executor

First, build the Python interpreter as a WebAssembly module:

cargo build --target wasm32-wasip2 -p executor --release

This creates target/wasm32-wasip2/release/executor.wasm.

2. Run the Server

The server will load the WebAssembly module and execute Python code. This will mount the current directory as read-only.

cargo run --release -p server --  -m .:.:ro -c "import os; print('Current directory contents:'); [print(f'  {item}') for item in os.listdir('.')]"

Now try it again without the -m flag.
