Warehouse is a versatile toolbox for managing flatpak user data, viewing flatpak app info, and batch managing installed flatpaks.




Flattool is a command line script designed to improve user experience with flatpaks. It streamlines flatpak management tasks, making them more efficient and user-friendly.
Permissions Reporter allows you to quickly validate the current security posture of entire local and/or network file systems at once. All with multiple export formats, command-line support, built-in scheduling, and much more.




jdPermissionStoreEdit allows you to directly view and edit the Flatpak Permission Store. This makes debugging easier when you are working with it (e.g. if you are developing an app to manage Flatpak permissions).
