With the Loki_AdminComponents module, the Loki Components behaviour (offered in the Loki_Components module) - which allows you to create complex UI components based on Alpine.js with AJAX syncing to the Magento backend - is brought to the Magento Admin Panel as well, to build grids and forms.
The core Loki_Components module actually just works in the admin - so if you want to build your own customer, you don't need this Loki_AdminComponents module. However, to build something as complex as a grid or a form, a lot of the functionality is involved. And this is added with this module and little effort.
