The 1.0 version shipped for the Mac in August 1989, with two versions, Serius Programmer that allowed the creation of new applications using the existing object library, and Serius Developer that allowed new objects to be written in external computer languages. This release was followed by 1.1 in October, which added a new Database object, and the 1.2 update in December. Serius was one of several visual programming tools that were available on the Mac in the late 1980s, such as TGS Systems' Prograph. The Serius89 Programmer product sold for $295 and the Serius89 Developer for $495. A review of Serius89 1.2 by "MacWEEK" concluded that it was "a novel, fascinating approach to 'desktop programming' and, despite its shortcomings, we believe it's an investment that will pay dividends in the future."
