Provide a Podman(Distrobox)/ Flatpak/ distro-agnostic image

[gluckgluckwasserbauch]

I really like the idea of this tool and find it a bit sad that it isn't available on other distros, like Fedora Atomic for example.

There is a very similar tool called BoxBuddy, that does almost the same, but doesn't look as sleek.

Would it be possible to provide a package for other distros too, so it gets a wider audience?

That would require apx in the host. It is possible to make a flatpak but we have no effort to maintain it. We for sure can help someone to make it.

Both apx and apx-gui (I am the package maintainer) are available in nixpkgs, and can be installed on any linux system (not just NixOS). To do so you will first need to install the nix package manager e.g. from here. Then it's simply a matter of running:
nix profile install nixpkgs#apx-gui

apx-gui running on OpenSUSE tumbleweed installed using nix:

As others pointed out above, there is no reason not to install the apx-GUI via Nix package manager. Nix should be standard on all distros. Flatpaks are often slow to load.
