What is it?

cx_Freeze turns Python scripts into standalone executables, so the program can be run on a machine without a separate Python installation. The generated executables are said to keep the performance of the original script, and the tool works on any platform Python runs on.

It is installed with pip or conda-forge and is documented on a Read the Docs site. The project includes samples, including one for building Windows service executables.

It suits developers who want to distribute a Python command-line tool or desktop application as a single program for end users who do not manage Python environments.

Key features

  • 01Builds standalone executables from Python scripts.
