It's the best tool for performance conscious users. It turns Python code into C/C++ code instead of freezing it, and, as an ahead-of-time compiler, performs several optimizations when compiling Python code into C/C++ code, improving performance significantly. Some of this optimizations are constant folding (which means that if a variable stores the result of 3+3, Nuitka already knows it is 6 at execution time), conditional-statement predictions, and quicker function calls. This benchmark can be useful for comparing Nuitka's performance against Python's performance. See More
PyInstaller is one of the best tools for easily freezing Python Scripts and Modules into self-contained executables. It can be used via CLI with a single command and without many configurations. This tool pulls all the necessary files and libraries needed into a file to have your program run on any PC as an executable app. See More
Python bytecode can be obfuscated by specifying an encryption key with a CLI command. This should prevent most forms of tampering with the executable, such as reverse-engineering it to extract the underlying Python code. While the bytecode is encrypted using AES256, it should not be confused for security because the key can be extracted from the executable. See More
