Wow! Thank you for that blog post, it was a great read.

I went through similar experience when experimenting with these tools, wish I can write a similar blog one day. Meanwhile, here's my takeaways:

APE/Cosmo

The project still has a long way to go especially for serving as drop-in-replacement for CC/compilers. And most programs I tried compiling required too much work (custom patches all over the place), to ever be able to scale up to thousands of packages.

Nix Bundle

This actually works & we used it quite a bit before running into the limitations. Ours is/was based on ralismark/nix-appimage, used bubblewrap & bundled to AppImages : https://github.com/pkgforge/nix-appimage

Guix/Guix pack

I was able to make guix pack relocatable, i.e work outside the store on another system with no guix, but the size was huge (even when compared to Nix bundle). And also guix is quite slow & expensive (even with substitutes), so we had to disable it.

You can still find a few packages from when we used to use guix

$ soar search guix
[-] bash#gnuguix.bash:bincache | 5.1.8 | static - GNU Bourne-Again Shell, the de facto standard shell on Linux (1.79 MiB)
[-] proot#gnuguix.proot-static:bincache | 5.3.0 | static - User-space implementation of chroot, bind mount, and binfmt_misc (1.15 MiB)

Appimage

Them requiring fuse2 is quite an old issue, and no longer true for appimages made post 2022. We have a lot of these properly made AppImages (even steam) that work on both glibc/musl and require no dependency. Check out: https://github.com/pkgforge-dev/Anylinux-AppImages

Python

There's only one project that provides truly static/relocatable python that work on both glibc/musl: https://github.com/leleliu008/python-distribution

All others are only partially static or meant only for either glibc or musl, not both.

Here, I would also like to introduce Sharun. This is the modern successor of staticx with many features, one of those include ability to pack python/pip packages very easily.

Here are some packages we have made using Sharun

$ soar search pypi
[-] anipy-cli#sharun.wrappe.pypi.anipy-cli:pkgcache | 3.5.8 | archive - Watch and Download Anime from the terminal (34.13 MiB)
[-] apprise#sharun.wrappe.pypi.apprise:pkgcache | 1.9.3 | archive - Send notifications from the command-line to popular notification services (23.83 MiB)
[-] archey#sharun.wrappe.pypi.archey:pkgcache | 4.15.0.0 | archive - A simple system information tool written in Python (24.88 MiB)
...and many more...

Soarpkgs (Formerly ToolPacks)

There are many more packages now (especially if you configure soar with soar defconfig --external): https://docs.pkgforge.dev/soar/readme/packages#total

But this came at the cost of discontinuing support for Android & Windows

We also had to discontinue upxed versions because we used up too much storage (yes, ironic)

The installation instruction & script have also been improved since, it now shows you what to do & where packages are installed.

Stal/Ix

We also added this as a source: https://github.com/pkgforge/soarpkgs/issues/191 And have a few packages already:

$ soar search stalix
[-] arti#stalix.bin_arti.stable:bincache | 1.4.1 | static - Tor reimplementation in Rust (22.61 MiB)
[-] fish#stalix.bin_fish.stable:bincache | 3.7.1 | static - Smart and User-friendly Command Line Shell (3.86 MiB)
[-] wget#stalix.bin_wget.stable:bincache | 1.25.0 | static - Tool for retrieving files using HTTP, HTTPS, and FTP (8.94 MiB)
[-] wget2#stalix.bin_wget_2.stable:bincache | 2.2.0 | static - The successor of GNU Wget, a file and recursive website downloader (10.50 MiB)

I also worked closely with the author to introduce binary caches & docker image.

Another project you might be interested in is ppkg: https://github.com/leleliu008/ppkg

This one can compile static binaries, even for BSDs. We have this in soarpkgs as well.

$ soar search ppkg
[-] alacritty#ppkg.alacritty:bincache | 0.15.1 | static - GPU-accelerated terminal emulator (14.75 MiB)
[-] dash#ppkg.dash:bincache | 0.5.12 | static - POSIX compliant shell that aims to be as small as possible (754.03 KiB)
... Total 334...

DockerC

Similar to your experience, dockerC indeed turned out to be quite underwhelming & we are slowly phasing these out from soarpkgs.
