Free chemical reactions database

I'm creating a program, which predicts reactions of compound. So, I need a database of chemical reactions. And I need both inorganic and organic reactions. But I can't use Scifinder or Reaxys because they are not free. Is there any free analogs?




In the current form the question is addressed, and assuming you took a look at a listing of software already in the field like [here](https://en.wikipedia.org/wiki/List_of_computer-assisted_organic_synthesis_software), I speculate the sheer number of organic reactions ([just some](https://en.wikipedia.org/wiki/List_of_organic_reactions)) alone renders such a task as a one-man / one-woman project too large. There is a lot of work associated to create such a database, or software. [Organic Synthesis](http://www.orgsyn.org/) is one open-access reference for organic reactions, yet the normal output is a html / pdf of the *reaction procedure*, and not a [\*.sdf](https://en.wikipedia.org/wiki/Chemical_table_file#SDF) (or other chemically relevant \*.xml-like) format. [Inorganic Synthesis](http://www.inorgsynth.com/) is a publication with similar intent as the former, yet not openly accessible.


Nevertheless, if you are interested in this topic, I suggest to consult the recent publications *Computer-aided synthesis design: 40 years on* ([DOI 10.1002/wcms.61](http://onlinelibrary.wiley.com/doi/10.1002/wcms.61/full)) as well as the just about a year old *Computer-Assisted Synthetic Planning: The End of the Beginning* in *Angewandte Chemie* ([English version DOI: 10.1002/anie.201506101](http://onlinelibrary.wiley.com/doi/10.1002/anie.201506101/abstract)).
