Is the Private Eye source code available?
Unfortunately, the source code for Private Eye is not currently available. I have spent many hours trying to figure out - even guess at - mostly undocumented APIs. There is some intellectual property value in the code. However, I will consider licensing it to interested companies for a fee. See Why is Private Eye free? for the reasoning.
 
If you are serious about purchasing the source code for Private Eye, then please send an e-mail to offer@stevengould.org and be sure to include the text "[Private Eye Offer]" in the subject line. If you fail to include "[Private Eye Offer]" in the subject line it will not get past our spam filter. In your e-mail, please describe your intended use of the source code and how much you are willing to pay for rights to the code.
