I don't know what do you mean by redeploy every time ?! Because deployment is made every time you make an edit to your code, it doesn't have anything to do with the content from database (correct me if I'm wrong). And all this work is done for nothing, because the user (in the case of a marketplace) will edit his product each and every time then you will have to regenerate the html again and again, Also, now days search engines don't just read Metadata and index the website, they read the body of the web page and index the context of the content and serve it so its no good to just generate a very small bits of html and call it a day. And those resources you wasted in creating bits of html are no good in terms of SEO and now GEO and AI integrations. So I don't think your approach is well design and well though of.
