Hang on, developers are developing!
You will find more information here shortly. For now, you can head over to ubports.open-cuts.org for a demo installation used by the UBports Community. OPEN-CUTS is still very much in development; get involved on GitLab!
Free and open source!
OPEN-CUTS is free and open source software originally developed by Jan Sprinz. You can find an overview of the source code and the terms of the license here.
