Like bauh which supports AppImage, Arch packages (including AUR), Debian packages, Flatpak, Snap and native Web applications. Source: 12 months ago

If you really want a GUI package manager that doesn't break EndeavourOS, I've had a good experience with bauh when I started using EOS. But I also do everything with yay now, as others have suggested, it is more convenient once you know the commands. Source: over 1 year ago

Lastly, deb-get + pacstall + bauh. All of these combined covers 99% of my software needs, much less need to find and install PPAs and .deb manually. Still not as convenient as AUR, but much better than it was before. Hopefully, eventually everything is on Flatpak, snap, or AppImage so I could just use Bauh for most apps, but for now, I'm glad that these tools exists. Source: over 1 year ago

Is it an AppImage? Did you make it executable? If you use a lot of AppImages then you may want to add DE integration via their utility. I do not use it, as it runs a backgroudn daemon, I prefer using bauh instead. Source: over 1 year ago

Write a Rails app and wrap it with https://todesktop.com. Source: over 2 years ago

I also came across flask-desktop, and todesktop.com which claim to be able to convert a flask app into a desktop app. I'm not sure how an https request would work there, but I'm considering looking into that as well. Source: about 3 years ago
