Platypus is a developer tool that creates native Mac applications from command line scripts such as shell scripts or Python, Perl, Ruby, Tcl, JavaScript and PHP programs. This is done by wrapping the script in a macOS application bundle along with an 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 programming for the native macOS APIs — with a few clicks you can create your own native 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/Cocoa. The source code is available on GitHub.
