Are you interested in building your blog from scratch? These quick tips may help:
Ship it as a static site. If you don't have to host Node.js/PHP/etc, fewer things can go wrong. You don't want to be paged because your personal blog went down.
Leverage Cloudflare Workers if you had a blog before, and you want to change the URL structure. Cloudflare Workers provide extreme flexibility and adding Permanent Redirects with them takes only a few minutes.
