Here probably, but what do you mean by "programmatic"? automated link builders? on page SEO analysers? or something else?
something else .. programmatic SEO = seo automated , generate massive Landing page and improves user experience
Sounds like a pipe dream. Pages created by "generators" are usually very poorly coded and don't improve the ux. Can you point to some examples where is done well?
As @sarahk indicates, anything you find will likely make things worse instead of better. Your only real choice is to develop your own generator to meet your exact needs. However, that is a MASSIVE chore that is probably beyond your capabilities. That said, in targeted instances it is possible to create your own generator. I have developed one for my own personal targeted use and it works pretty well, BUT I have been tweeking it for over 15 years to get it to where it works for me. I even tweeked it more today. And it will not work for anything other than what I use it for.
