You can set up any static site generator (like Astro or Hugo) with a pre-made blog template. Then you'll just have to write posts in markdown files and the generator will handle the rest.

(Or you can write a custom template in any of those, they both don't add any JS or anything else to your page by default unless you explicitly add it. I like Astro more since it's basically just HTML with extra features unlike Hugo which uses a separate templating language, but they're all pretty much the same)

You can deploy it automatically and completely for free on platforms like GitHub Pages or Cloudflare Pages, which are pretty easy to set up and will automatically build and deploy new versions of your site on every git push.
