I'm not a TCL user, but from the description of wduquette is sounds similar to Python's zipapp

The definition of "standalone application" is a bit stronger - what's always been possible with "Tclkits" has been to embed the application code in an interpreter binary and distribute that, and the new core zipfs supports that as well.

Yes, exactly. You can package up your entire scripted application, plus all resources, into a single executable, and distribute that single file.
