Ok well this doesn’t work on Mac, so much for not needing to cross-compile on every architecture. It’s because of the OSX Gatekeeper but if majority of people need to self-sign or otherwise compile this binary I’m not sure if it is that portable be it if it’s only a Mac thing. This dumps the zip content directly on the wire skipping an extra kernel write. There have been attempts before to run the same binary on multiple architectures by inserting magic headers without having to recompile. There are shell/batch versions of the same thing [0]. The issue is such projects usually never get much traction since every programmer is wedded to their choice of OS and typically relies on APIs specific to each system. There are also “fat binaries” which accomplish the same thing if one truly wanted a cross platform single executable. There isn’t a huge need for them currently and not just because they’re “fat” (something this approach seems to tackle primarily) so I expect for the same reasons there won’t be many needs for this approach either.
I see a lot of people making the comparison between this and the OG Linux tools. I absolutely don’t think this qualifies as one, most old Linux tools are irreplaceable or at least were when they first came out and there were no alternatives. Serving a bundled zip file on a web server across many different platforms is not something people are dying to do. You can run a web server like nginx or Apache to index your files or if you really hate those why not a single line command which is supported on almost any platform:
python -m http.server 8080
