CloneCD is proprietary optical disc authoring software that makes exact, 1:1 copies of music and data CDs and DVDs, regardless of any digital rights management (DRM) restrictions.

It was originally written by Oliver Kastl and offered by Swiss company Elaborate Bytes, but due to changes in European copyright law, they were forced to take it off the market.

The software was subsequently sold by SlySoft, a company located in Antigua and Barbuda, whose legislation does not ban the circumvention of DRM schemes.

In older versions of "CloneCD", the features "Amplify Weak Sectors", "Protected PC Games", and "Hide CDR Media" were disabled in the United States of America and Japan.

Changing the region and language settings in Windows (e. g. to Canadian English) and/or patches could unlock these features in the two countries.
