AppWare was a rapid application development system for Microsoft Windows and the classic Mac OS based on a simple graphical programming language. Applications were constructed by connecting together icons representing objects in the program and their commands. The resulting logic could be compiled on either platform and typically only required minor changes to the GUI layout to complete the port. Originally introduced in 1989 as Serius89, and eventually becoming Serius Developer, it is best known as AppWare when it was briefly owned and marketed by Novell. Novell sold the product off in 1995 or 96, it was renamed MicroBrew, and development eventually ceased in 1997.
