PyInstaller

PyInstaller bundles Python applications and all their dependencies into a single, standalone executable for distribution.

PyInstaller is the definitive tool for packaging Python scripts into self-contained executables (EXEs on Windows, .app on macOS). It analyzes your script, recursively collecting all required modules, libraries, and even the active Python interpreter itself. The result is a single package that users can run immediately—no Python installation or environment setup is necessary. It supports Python 3.8+ and is tested against major platforms: Windows, macOS, and Linux. The core command is simple (`pyinstaller myscript.py`), with the `--onefile` option being a preferred method for creating a single, clean executable file for end-user deployment.
