Harbour is a program for Windows which serves as a compiler for the xBase superset language called Clipper. It is an open source project that can be used to develop applications to be distributed on a free or paid basis.

Cross platform development

One of the standout features of this software is its cross platform compatibility. This means you can create programs capable of running on various operating systems. To be more exact it is possible to make projects for the following OSs:

Linux;
Windows;
macOS;
iOS;
Android;
BSD;
nix.

The utility is equipped with a command line interface, which might pose a challenge if you do not have prior experience with such controls. However, it is important to note that extensive documentation is readily accessible both online and within the installation folder.

Performance and conclusion

In addition to cross platform development capabilities, the tool supports Replaceable Database Drivers. Thus, you have the option to work with multiple data sources. This enables you to scale your applications. There are also several example projects to help you learn more about the functionality.

The program maintains low CPU and memory usage, ensuring that it will not burden the system performance. All factors considered, Harbour is a convenient solution if you are interested in compiling apps using Clipper. To decompile Visual Basic projects, you may use a utility named VB Decompiler.
