Features of the View version.
There is a free analogue of the Attribut & co module. Actually, this is the same module, only with a non-commercial license.

The limitations of the free version relate to physical changes in the database. You can perform any actions with Attributes or Values as in the paid module, but no changes will occur in the Database. Those. after reloading the page, everything will become as it was. The free version is designed to explore the possibilities and understand the convenience of working with attributes, as well as to make sure that the module can work on your OpenCart store.
