Here are the best options among them.
1.GNOME Software
GNOME Software is the app store that comes with many versions of desktop Linux.
It offers excellent Flatpak integration, so it’s an easy way to discover new Flatpak apps.
GNOME Software can also display which sources, known as Flatpak remotes, your system is downloading apps from.
If GNOME Software isn’t preinstalled on your box, you’re free to install it yourself.
This is known as sandboxing, and it has been a work in progress.
For the most part, apps don’t even inform you what permissions they need.
Without sandboxing, your system can be open to all sorts of security risks.
On the flip side, restricting permissions can break certain apps.
But once you do gain understanding, the solution is usually to download andlearn how to use Flatseal.
3.Warehouse
There’s a lot of information contained within a Flatpak.
It serves as a storehouse of nearly everything you might want to know about a Flatpak.
Warehouse also mitigates one of the few minor flaws of Flatpaks: automatic updates.
With Warehouse, you’re able to tell an app to ignore updates.
This way, if a future release comes with bugs or substantial changes, it wont impact you.
Warehouse also lets you downgrade to a previous version of the app.
Like GNOME Software, Warehouse can list your available Flatpak remotes.
you could also add your own repo file or URL.
Another standout feature of Warehouse is the ability to view the folders that store your Flatpak app data.
Then you have the option to delete this folder.
And Warehouse isn’t limited to the software you have currently installed.
Unlike Warehouse, it doesn’t attempt to do anything else.
Flatsweep is isolated just to your Flatpak apps.
Open Flatsweep, wipe your files, and move on.
Flatpak Largely Just Works
Flatpak makes getting apps on Linux easier than it has ever been.
But the format, or the tools built around it, still has a few kinks to work out.
This is true of other alternatives, like Canonical’s Snap package format.
But as time goes on, the need to install extra tools may gradually go away.
