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.
Less secure than blindly installing flatpaks or appimages?
Appimages work “everywhere” so they are better for distributing malware.
Flatpaks are normally not installed from random sources and I hope it stays like that.
So yes and no.
(Also Flatpaks are, at least in theory, sandboxed and can’t mess with your system stuff unless you allow them to)
Not yet.
The permissions are too comlicated (unlike “allow documents access” on Mac for example)
And there is no Desktop GUI integration for opt-in to permissions. So install, open Flatseal / KDEs settings, harden, then run.
