I know this is weird, but maybe have a look into Fossil ( https://fossil-scm.org/ https://fossil-scm.org/ ). Not exactly a static site, but the whole repository

I know this is weird, but maybe have a look into Fossil ( https://fossil-scm.org/ https://fossil-scm.org/ ). Not exactly a static site, but the whole repository (all posts, comments, etc.) is a single SQLite database file. And, fossil is a single binary that can be run as a standalone server, as CGI or FastCGI as well.
