However, there are synonyms for vaporwares that you can use to describe such fake products. One of the most popular is "snake oil software," which refers to software that claims to solve every issue but is, in reality, useless or harmful. Other similar synonyms include "vaporwareware," "griftware," and "scamware." Although these terms vary in their intensity, they all suggest deception and fraudulence associated with software products that don't live up to their advertised claims.
