Replacing pyinstaller with 100 lines of code

The python project itself lets you download embeddable python, you don't need to get it from random sources. It works great, you can install all your pip packages, zip it backup and it just works.

Nuitka does something like this too, but in my experience does not handle signals as well as PyInstaller.

Do you do extract, fork process, cleanup? Does it handle signals sent to the extract process as if they were sent to the actual program?

Important to note that PyOxidizer, the tool that gets a special mention at the end of this blog post, is currently in a zombie state and not getting updates [1]. So alternatives in this space are extremely welcome!

There is also PyApp, which I think is really promising. The docs there are not that comprehensive yet and maybe a bit confusing, but the packaged programs usually work out of the box, unlike with pyinstaller.
