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 and has been continuously developed and maintained for a very long time (since 2003). If you find this program useful, please make a donation.
Platypus can also be installed via Homebrew (may not be latest version):
$ brew install --cask platypus
Platypus lets you select one of several different user interfaces for your script.

$ make build_unsigned

Platypus is very old software, dating back to the early days of Mac OS X, around 2003, when I was first learning to use Objective-C and the Cocoa APIs. I made many beginner mistakes, some of which remain in the structure of the code. This software has since gone through about four dozen significant versions. It has been patched, bugfixed, streamlined to include new features and was transitioned over to modern Objective-C a few years ago. It's not how I would write it today.
With these caveats in mind, here is the BSD-licensed source code to Platypus.
