How to manage Flatpak permissions graphicly?

Finding difficulties to manage Flatpak permissions using command lines? Maybe you should give Flatseal a try.

The main purpose of Flatpak is to provide a centralized service for distributing applications. But while Penguin users enjoy the taste of updated and secured Linux apps, they have hard time managing Flatpak permissions for the lack of graphical front-end which helps them do so.

Here the important of the Flatseal utility, which developed by the enthusiast engineer Martin Abente Lahaye, appears.

What is Flatseal?

According to FlatHub "Flatseal is a graphical utility to review and modify permissions of Flatpak applications."


Flatseal is available as a flatpak app that you can easily install it using the following command line:

flatpak install flathub com.github.tchx84.Flatseal{codeBox}

Now, run it from application launcher and let's discover it.


Flatseal is a simple clean Linux app that makes Flatpak permissions management very easy. However, its interface looks ugly on my KDE plasma system. The screenshot below provides an overview of the interface.


  • In the top-left you have a simple search box, which helps you find the desired flatpak apps.
  • Just below the search box, you find your flatpak installed application list.
  • On the wide right sidebar, there is a long app-specific list of permissions: socket, filesystems, devices...


You can use this useful app by following this steps:

  1. Launch Flatseal from app menu.
  2. Select an application from left sidebar.
  3. Modify its permissions: You should use this powerful feature carefully and only change the needed ones.
  4. Restart the application for the changes to take effect
  5. Something is wrong? Don't worry,  just click on the reset button (on the top right bar).


In summary, Flatseal is a very useful app that makes flatpak's permission management effortless. However, the interface should be updated to bring a better integration with desktop environments, especially KDE plasma.
