Avoid switching between Clojure and bash scripts. Enjoy your parens on the command line. Leveraging GraalVM native-image and the Small Clojure Interpreter, babashka is a self-contained and instantly starting scripting environment. Babashka comes with scripting batteries included: tools.cli, cheshire, babashka.fs, babashka.process, java.time and many more libraries and classes. Babashka scripts work on linux, macOS and Windows. Besides the built-in libraries, babashka is able to load libraries from source, tapping into the world of already existing Clojure libraries. Babashka supports real JVM threads and like Clojure, supports futures and dynamic thread-locally bound vars. Babashka features a built-in task runner which covers the most popular use cases of make, just and npm scripts. Babashka can shell out to other CLI programs like you are used to in bash. It goes one step further and offers seamless integration with other binaries using the pod protocol.

The freeWrap program turns TCL/TK scripts into single-file binary executable programs. freeWrap can wrap TCL/TK applications that consist of multiple script and binary files. freeWrap combines all the files together into a single executable file.

Logic Programming and Deductive Database system (Tabled Prolog) for Unix, Mac, and Windows.

PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.
