PyPy is described as 'Interpreter that implements the Python programming language, based on the RPython compiler framework for dynamic language implementations' and is an app in the development category. There are eight alternatives to PyPy for a variety of platforms, including Linux, Mac, Windows, BSD and Self-Hosted apps. The best PyPy alternative is Python, which is both free and Open Source. Other great apps like PyPy are Nim (programming language), Mojo, Jython and Stackless Python.
Python is an interpreted, interactive, object-oriented, extensible programming language. It provides an extraordinary combination of clarity and versatility, and is free and comprehensively ported.

Mojo is a specialized artificial intelligence (AI) programming language developed by Modular Inc. First released in May 2023, it is designed to become a superset of Python, with the performance of C.
United States
Jython, successor of JPython, is an implementation of the Python programming language written in Java.
Stackless Python is an enhanced version of the Python programming language. It allows programmers to reap the benefits of thread-based programming without the performance and complexity problems associated with conventional threads.
MicroPython aims to implement the Python 3.4 standard (with selected features from later versions) with respect to language syntax, and most of the features of MicroPython are identical to those described by the “Language Reference” documentation at docs.python.org.

Shed Skin is an experimental compiler, that can translate pure, but implicitly statically typed Python (2.4-2.6) programs into optimized C++. It can generate stand-alone programs or extension modules that can be imported and used in larger Python programs.
