Same here. Started ages ago with DokuWiki and then decided to try GitHub Pages. Transferred everything over, but then wanted some kind of search. So, I’ve implemented a custom Google search. Wanted some way for visitors to leave comments, so added Disqus. And in the end it was a potpourri of different services and a whole lot of JavaScript.
A few years ago I wanted to own my data again and not depend on external services, so exported the Disqus comments and after playing around with Serendipity ended up with Wordpress.
Was able to import the comments and the Markdown pages and there are even plugins to make it publish everything in the Fediverse. Made it all work using SQLite and enabled auto-updates. It’s basically maintenance-free.
