I'm still thoroughly happy with going for a static site for 10ish years - first raw HTML, then Jekyll, now Hugo
But in the last few years I've been paying for bandwidth on my site - largely due to consistent traffic usage, as well as some big spikes, and lots of scraping! - so I'm currently hitting ~$30/mo on AWS due to needing AWS WAF on top of Cloudfront + S3
(I'd ended up needing to pay much more /mo for Netlify, bandwidth wise, so migrated to AWS)
