I’m in the process of converting a Wordpress blog to a static site. We did have significant comment traffic back in the day so I did look into how to maintain comment functionality. I found Comentario
https://docs.comentario.app/en/ which is a standalone comments engine that can be self-hosted and linked to the blog page. Single stand alone Go executable, SQLite database - seems dead simple and has built-in ways to migrate Wordpress comments.
Still, since we do not get that many comments these days, I’ll probably postpone it and just provide a static render of existing / historical comments which does have value for archival and discussion purposes.
