Platypus is a developer tool that creates native Mac applications from interpreted scripts such as shell scripts or Perl, Ruby and Python programs. This is done by wrapping the script in an application bundle along with a native executable binary that runs the script.

Platypus makes it easy for you to share your scripts with people unfamiliar with the command line interface, without any knowledge of the native Mac APIs — a few clicks and you will have your own Mac application. Creating installers, maintenance applications, login items, launchers, automations and droplets is very easy using Platypus.



Platypus is free, open-source software distributed under the terms of the three-clause BSD license. It is written in Objective C for the Cocoa application programming interfaces. The source code is available on GitHub.

The latest version is Platypus 5.2, released on March 3rd 2017. Platypus and Platypus-generated applications require Mac OS X 10.7 or later, and are 64-bit Intel binaries.

If you want to target 10.6 and/or 32-bit systems, version 4.9 continues to work just fine. If you want to target 10.4 and PowerPC users, you can use version 4.4.
