The xPack Windows Build Tools Frequently Asked Questions
Nix also provides reproducible builds, why not use it?
The short answer is… “because of Windows”.
Nix is a remarkable project that carefully controls versions down to individual libraries. However, it relies on file links, which are either unavailable or unreliable on Windows.
As a result, Nix is currently only available on GNU/Linux and, with some limitations, on macOS. Additionally, mastering the Nix language requires significant effort.
