## What it is
PyInstaller is a tool that bundles a Python application together with its dependencies and the Python interpreter into a stand-alone folder or single executable file. It analyzes import statements to discover all required modules and libraries, producing self-contained apps that run without Python installed.

## Use cases
- turn a python script into a standalone exe
- package a python app for users without python installed
- bundle a python program with all dependencies into one file
- distribute a python gui application to windows users
- create a single-file executable from a python project
- freeze a python application for macos
- ship a python tool as a self-contained binary

## When to choose
- you need to distribute a Python app to end users who don't have Python installed
- you want a single executable or folder bundle for Windows, macOS, or Linux
- your app uses common packages like numpy, PyQt, or matplotlib that PyInstaller bundles out of the box
- you need code signing support on macOS

## When to avoid
- you need cross-compilation - PyInstaller only builds for the OS it runs on
- you want to reduce binary size drastically - bundles include the full interpreter and dependencies
- you need to hide source code securely - bundled bytecode can be extracted
- you target niche platforms like AIX or Solaris where support is untested and unguaranteed
