What it is

Py2app is a tool that converts Python scripts into standalone Mac OS X applications, making it easier to distribute your software without requiring the end user to have Python installed. It's particularly useful for developers who need to package their applications for distribution on macOS.

Py2app stands out for its simplicity and effectiveness in converting Python scripts into standalone applications specifically for macOS users, without requiring them to have a Python environment installed.

When it fits — and when it doesn’t

A good fit for

  • Python developers looking to package and distribute their applications on macOS

  • Developers needing to create self-contained executables without requiring the user to install Python

Look elsewhere if

  • Developers targeting platforms other than Mac OS X, as py2app is specific to this operating system.

  • Projects that require cross-platform compatibility out of the box.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited to macOS environments

    py2app is specifically designed for creating standalone applications on Mac OS X and does not support other operating systems like Windows or Linux.

  2. 02

    Complex setup process

    Requires a detailed understanding of Python packaging, environment management, and macOS application structure to properly configure and build the standalone applications.

  3. 03

    Poor documentation for advanced configurations

    While basic usage is well-documented, more complex scenarios such as customizing application behavior or handling specific dependencies are not thoroughly covered in the official documentation.

  4. 04

    Performance overhead due to bundling Python interpreter

    The resulting standalone applications include a full Python runtime which can increase the size of the final executable and potentially affect performance compared to native applications.

What it does well

  • Converts Python scripts into standalone Mac OS X applications

  • Supports packaging of dependencies and resources within the application bundle

  • Provides flexibility in customizing the application's appearance and behavior
