This is kind of a bad comparison. Theoretically, malicious authors could sign their Flatpak packages and Flatpak could verify it with cryptography. It doesn't matter if you're downloading a "crypto-wallet" that's really just a phishing exercise.
Will still be using 4.79 GiB?
It will use more, but not exponentially more if de-duplication works as well as is claimed. The problem with AppImages is that they don't include all of the dependencies, making them less reliable. At the expense of storage space, Flatpak bundles everything for reliability.
De-duplication works better the more Flatpak applications you have installed. e.g. de-duplication saves TheEvilSkeleton over 50GB of storage space here: https://tesk.page/2023/06/04/response-to-developers-are-lazy-thus-flatpak/#but-flatpaks-are-easier-for-end-users
You don't have many Flatpaks installed, but you happened to install applications that depend on three different runtimes (Freedesktop, GNOME, KDE), which is where a lot of the weight is coming from. Install 20 more Flatpaks and see what happens.
Well, if you think about it, the Freedesktop Platform is essentially a distribution. And Flatpak used to be called "xdg-app". If you've got all your graphical applications installed via Flatpak, with GNOME, Systemd, glibc, GRUB and all the core dependencies only packaged for the base system (essentially Arch's core repository), that's pretty much a Freedesktop OS.
Hey, maybe we could use Snaps for the base system and Flatpaks for the userland? Or are these the kinds of ideas that get people stoned?
if you have a flatpak with an uncommon library
In this case, you're responsible for packaging it yourself. This usually means specifying the git URL and build options in the manifest. You can see Krita doing this in their manifest because they don't depend on the KDE Platform, as they need much older dependencies. So they're responsible for over 1000 lines worth of dependencies.
The Freedesktop Platform is essentially a distribution unto itself, and I don't think there's ever been a case of dependencies in that distribution not being kept up-to-date.
Distro libs are less likely to have this happen because very few distros have a bus factor of 1—there’s usually someone who can take over.
Well...debatable. There were over 1200 orphaned packages in Debian last year, many of which had not been maintained in over 3 years.
In general I agree, though had something to add regarding these points:
by defaults the sandbox is pretty good
This is a rather major problem with Flatpak; the maintainer decides what permissions they need by default, not the user. The user needs to retroactively roll them back or specify global options and manually override them per-app, but that's not user-friendly at all. Though many Flatpaks do have good permissions because Flathub maintainers step in and offer suggestions before approving the Flatpak for publication, there are a number of Flatpaks that punch big holes in the sandbox; so much so that they might as well be unsandboxed.
But Bottles has a great sandbox, for instance, which is just what you'd want when running lots of proprietary Windows applications you maybe don't trust as much as your Linux-y software.
It's better than what we have with traditional packages but it can sometimes get in the way and not all beginners can easily figure out how to fix permissions issues with Flatseal. This will probably improve as we get more portals built.
some apps are less maintained and use EOL runtimes etc
Not much is different for distribution-maintained packages, either. See TheEvilSkeleton's post about how there are over 1200 unmaintained packages in the Debian repositories, and even over 400 in Arch's much smaller repositories that are outdated (!). At least Flathub applications are usually maintained by upstream, and so are usually as up to date as they can be.
not suited for some apps like terminal apps or system stuff
This isn't really true. It's only true when terminal applications need privileged access to something. Flathub ships Mesa userpace drivers and NVIDIA's proprietary userspace drivers just fine. You can package something like yt-dlp in Flatpak just fine with --filesystem=host. Hell, they've even got Neovim on Flathub. Sure, it's a little more cumbersome to type, but you can always create an alias.
Flatpak is not suitable for all graphical applications, either. Wireshark's full feature-set cannot be supported, for example.
I would add that:
flatpak update --commit. Much harder with traditional package systems, and you'll probably need to downgrade shared libraries too.master or with a few patches, all you really need to do is clone it from flathub/whatever, change a few lines, and it has a very high chance of building properly. No need to figure out dependencies, toolchains, or sane build options. And it's all controlled from an easy-to-read and modify file.Most Flatpaks depend on the Freedesktop Platform runtime, or GNOME/KDE runtimes, which are derived from it. This contains several hundred common dependencies and librarires programs need, like gcc and python. When you update the runtime (change it from 22.08 to 23.08 in the manifest), all the dependencies are updated too. Many simple applications don't depend on many more dependencies than are available in the runtime. Some...have more complicated dependency trees.
But counterpoint: the developer will update the dependencies when they are known to work properly with the application. Upgrading GTK3 to GTK4 in the GIMP flatpak will just break the application. Same thing with Krita and the dozens of patches to libraries it depends on. If you upgrade the application in the name of security before it's compatible, all you end up with is a broken application. Which I guess is more secure, but that's not helpful to anyone.
When my KDE screenlocker crashes on Wayland, all my monitors tell me to switch to a TTY and run a manual unlock. Which is reassuring!
If it doesn't work in Wine (the only reason I've encountered so far is DRM), I just run it in a Windows VM. I play mostly visual novels, so it's not that much slower. For Anti-Cheat games, I boot into my Windows 10 installation. I still haven't quite figured out what I'm going to do with that installation come October 2025.
Eminently logical.
I'm saying that Flatpaks use more storage for reliability, and that AppImages are less reliable because they rely on system dependencies in some circumstances.
This is why AppImages are less reliable. Flatpaks either work for everybody, or they don't work at all. AppImages might not work if you're on a "weird distro" or forgot to install something on your system.
Packaging your software with Flatpak does not mean you won't have issues. But when you do have issues, you know they'll be an issue for everybody. So when you fix it, you also fix it for everybody.
For example, the RetroArch package was using an old version of the Freedesktop Platform, which comes with an old version of Mesa. When they bumped the version (just changing it from
22.08to23.08), the problem was fixed: https://discourse.flathub.org/t/problems-with-mesa-drivers/5574/3
