RustPython is an implementation of the Python programming language written in Rust. Its goal is to provide a fast, embeddable, and secure interpreter that can be integrated into Rust applications or used standalone. Because it’s in Rust, it benefits from memory safety and modern tooling, allowing developers to compile Python into efficient binaries or embed it as a scripting engine in Rust projects. The interpreter aims to support the Python standard library, dynamic typing, garbage collection, and common builtins, although full compatibility is a work in progress. ...

wasmi is a lightweight WebAssembly interpreter written in Rust that is designed to execute Wasm binaries efficiently in constrained or embedded environments. Unlike JIT-based runtimes, wasmi focuses on interpretation, prioritizing portability, determinism, and low resource usage over maximum raw performance. It is particularly well-suited for blockchain systems, embedded devices, and other contexts where predictable execution and minimal dependencies are critical.

...One of its key goals is to enable Ruby to run in environments where traditional implementations struggle, including WebAssembly and sandboxed or untrusted execution contexts. Artichoke features a modular architecture composed of multiple Rust crates, allowing developers to customize and embed the interpreter into their own applications. It includes tools such as a command-line interpreter and an interactive REPL, making it usable both as a runtime and a development environment. The project emphasizes experimentation with advanced features like alternative garbage collection strategies, parallel execution, and ahead-of-time compilation.

This is an experimental Javascript lexer, parser and interpreter written in Rust. Currently, it has support for some of the language.

SpaceWasm is a NASA JPL WebAssembly interpreter designed for resource-constrained spacecraft systems. It implements a constrained form of the WebAssembly 1.0 specification for executing portable onboard programs. A streaming decoder reads modules in chunks, validates them in one pass, and converts instructions into an interpretation-focused intermediate representation. Its custom memory model uses fixed-size pages to provide deterministic allocation behavior and avoid panic on allocation failure. ...

...Its design is motivated by the desire to reduce runtime overhead and binary size compared to interpreter-based solutions, especially in environments where performance and portability are critical.

py-spy is a sampling profiler for Python programs. It lets you visualize what your Python program is spending time on without restarting the program or modifying the code in any way. py-spy is extremely low overhead: it is written in Rust for speed and doesn't run in the same process as the profiled Python program. This means py-spy is safe to use against production Python code. py-spy works from the command line and takes either the PID of the program you want to sample from or the command...
