A friend and I would like to try out Jammr but we do not use either Ubuntu or a distro that handles debs so I wonder if you can offer a distro agnostic option like AppImage or Flatpak?

Yes, absolutely. This seems to be the future of third-party software distribution on Linux.

I plan to look at both Flatpak and Snap for future jammr releases. That should cover most distros.

Thanks for the pointer to AppImage. I'll take a look!

A Flatpak is now available here: https://flathub.org/apps/details/net.jammr.jammr
