I love the website too! Came here to sing similar praises. What's the stack you're using?
I keep it super simple and don't do "the proper way" of things at times (e.g. the blog index is manually done by me). But that keeps it simple & independent to me. Next.js here is just a detail, I can always move to some other React-based static site generator.
It's hosted at Cloudflare.
The design is heavily inspired by https://turbopuffer.com/, I don't deserve any praise for that.
I had actually looked in your GH and hadn't found this - it 404s when I use this link so the repo may be private
