Aubit 4GL is a free opensource work-alike for Informix 4GL. The project was started by Mike Aubury of Aubit Computing Ltd, who continues to contribute most to it. A number of other contributors have include Andrej Falout, John O’Gorman, Sergio Ferreira, Walter Haslbeck. Recently, other companies have joined the Aubit4GL brotherhood with the intention of contributing to the development of independent graphical frontends.

Where Informix 4GL was locked into working only with Informix’s own database engines: SE and IDS, Aubit 4GL can work with any SQL compliant engine. Currently supported engines are Informix SE and IDS, PostgreSQL, SAPDB, mysql, SQLite3, and using ODBC (unixODBC or iODBC on Linux/Unix) any other engine for which ODBC interfaces exist.
