As I’ve found out recently, finding true alternatives can be difficult. Take bread for instance. I just discovered Bimbo Bakeries own at least 26 brands. So when you’re on the bread aisle you probably have a moderate to high chance of buying one of their products.
If it’s a mostly self-contained app, like a game or a utility, then Flatpak is just fine. If a Flatpak needs to interact with other apps on the host or, worst case, another Flatpak it gets tricky or even impossible. From what I’ve seen though, AppImage and Snap are even worse at this.
