Last time I was checking this index is pretty crappy (as in inaccurate and spotty; for instance it claims that swiss citizens can access North Korea visa free). Henley & Partners have one that is more reliable. I spot checked last year's version of H&P and that website against timatic which is the source for both and H&P was at least mostly correct. Unfortunately there is no good way to get access to this information in machine readable format. It's all free form text and full of special rules.
