Appimages totally suck, because many developers think they were a real packaging format and support them exclusively.
Their use case is tiny, and in 99% of cases Flatpak is just better.
I could not find a single post or article about all the problems they have, so I wrote this.
This is not about shaming open source contributors. But Appimages are obviously broken, pretty badly maintained, while organizations/companies like Balena, Nextcloud etc. don’t seem to get that.
AppImages are great and easy to use and they can be very easily archived. Today I tried to archive a Flatpak package (yuzu) and it was a pain, complicated and gave up in the end. I end up archiving multiple versions of the AppImages and continue using the Appimage for this emulator. Also sometimes Flatpaks do not work correctly, and I (and any other user) have to figure out what settings and configuration, rights and other stuff is needed to setup with Flatseal. Recently I solved the open links issue with Flatpaks, and found out a certain portal was required to be installed. Also sometimes the theming is not correct too.
All in all, I use Flatpak still and AppImages too, each for their own reasons. The lack of repositories and not needing an installation for being functional is not a problem with AppImages, because that’s the entire point of it. They can be automatically generated and ready for download, regardless of any repository, directly on Github from the developers. There is even a program, RPCS3 (a ps3 emulator), which can check and update itself and list all changes since last update.
If you download AppImages from shady places, then off course its shady and insecure. Just like installing any software without knowing what you are doing is insecure. So that’s not a point against the format itself. The argument “Duplicated libraries” is hilarious, if we speak about AppImages vs Flatpak, because Flatpak has duplicated drivers (especially with Nvidia, I know how bad it is because I had Nvidia cards before) and desktop environment versions, just because certain versions of the application needs it.
I don’t understand these evangelism for packaging formats. Flatpak, AppImage, native system packages and other formats have their own uses and are all useful and not bad.
