Guix/Nix does this better across many programming languages. Unlike language-specific package managers, Guix is fully recursively reproducible ("bootstrappable"). And Nix isn't terribly far behind, either.

Julia itself is not even reproducible: https://github.com/JuliaLang/julia/issues/25900 https://github.com/JuliaLang/julia/issues/34753

Note that those issues are about deterministic performance, not results. Also guix and nix appear to be Unix only, which severely limit their use for Windows users. One of the places Julia really excels with reproducibility is inter OS, yes there are probably some bugs, but the ability to manage versions cross OS this easily is something I'm not aware of a good alternative for.

Not at all. The issue is that the default sysimage distributed with Julia cannot be reproduced across machines, e.g. there is no proof that it hasn't been tampered with. This is an open issue in Guix and Nix, though it affects all platforms.

There really is no such thing as reproducibility in Windows, at least not in the sense outlined in bootstrappable.org . If you care about reproducibility, you've chosen the wrong platform.

Sorry for the confusion. I meant reproducibility in the sense that I can have a git repo to share code between a laptop running windows and a cluster running Linux, and if I run the program on both I'll be running the same program (same libraries, same versions, equivalent binary blobs, etc). I don't mean that it can give you a cryptographic proof that your code hasn't been tampered with maliciously, just that you can debug your code locally, then deploy it to whatever you want and be pretty sure that it will still work even if you deploy to a different OS an/or cpu architecture.
