Applications created by Hardcoded Software are open source. They also used to be fairware, an innovative development model that tried to reconcile "sharware-type" open source applications with a "shareware" type of revenue. It was partly successful, but in march 2013, after two years and a half of fairware, I began phasing it out.
HS apps are now "purely" open source or on they way to being so. The only exception is dupeGuru, whose transition I'll delay a bit (I explain why in the article linked above).
This website is here for legacy purposes, that is, to avoid creating dead hyperlinks and to explain what fairware has been while it lasted. The Stats page will give you contribution statistics for those 2.5 years.
