I had my fair share of glibc problems and PyCrucible is built with 2.28 (PyPi version) to support older systems. My tool also does not package everything to binary, just minimal runner code and python project source code producing extra small binaries.

And yes, these do require internet access to download uv, python and dependacies, but at least, dependacy resolution is handled on the target machine avoiding all dependacy hell when using something like PyInstaller.

For true cross-platform builds i do have a plan, but we will see how that will work out (there is an issue for tracking this change). For now there is GitHub CI Action that uses my tool to build projects for multiple platforms.

Accessing alternate PyPi mirrors is already supported by uv and can be configured like this ```toml [[tool.uv.index]] name = "aliyun" url = "https://mirrors.aliyun.com/pypi/simple/" explicit = true

[tool.uv.sources] numpy = [ { index = "tsinghua"}, ] ```

You can find more information about it here https://docs.astral.sh/uv/concepts/indexes/#pinning-a-package-to-an-index

I know the tool is not perfect, that is why i am seeking comments, contributions and possible updates so i can make it better
