Platypus icon

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 app binary that runs the script.

Platypus makes it easy to share scripts and programs with people who are unfamiliar with the command line interface. Native, user-friendly applications can be created with a few clicks. It is very easy to create installers, droplets, administrative applications, login items, status menu items, launchers and automations using Platypus.



Platypus is free, open source software distributed under the terms of the three-clause BSD license and has been continually maintained and developed for a very long time (since 2003). It is written in Objective-C/Cocoa. The source code is available on GitHub.
