It is common for a single generic product to be produced in a factory, whereby the manufacturer then sells that product to whatever company/brand wants to put their label on it. The result is several different "clones" of that product, each with different brand labels.
What is the word used to describe these "clones"? Note that I'm not looking for the word "clone" because that implies an original was copied, and bears a similar connotation to "knock-off".
Example usage would be in the context of a heading on a website or user interface:
- Brand 1
- Brand 2
- Brand 3
- Brand 4
Whereby the implication of this list is to enumerate identical alternatives/options to a given product from other brands.
