You can, but that completely negates the reasons why you’d want to have a repo system in the first place. You gotta do the legwork to get updates, for example.
And to be explicit about it, zypper, dnf, apt, flatpak all have a specific mechanism to declare repositories and one ‘update’ check will walk them all.
snap does not, and manually doing a one off is useless. AppImage also has no ‘update’ concept, but it’s a more limited use case in general, it’s a worse habit than any repository based approach.
This isn’t necessarily true - a developer choosing to not include their app in a repo can always opt for a self-updating mechanism.
Don’t get me wrong - repos and tooling to manage all of your apps at once are preferred. But if a developer or user wants to avoid the Canonical controlled repo, I’m just pointing out there are technically ways to do that.
If you’d question why someone would use snap at all at that point… that would be a good question. The point is just that they can, if they want to.
The main reason is that it is completely controlled by Canonical, with no way to add alternative repos.
It’s worth noting you can bypass the repo, and install snaps that you downloaded from some other source - see https://askubuntu.com/questions/1266894/how-can-i-install-a-snap-package-from-a-local-file.
That doesn’t give you a separate “repo,” but it does allow you to install snaps from anywhere.
