I started with Jekyll which had tons of freely available themes (no link) then went on to Hexo but it was slow ( https://100dayz.js.org https://100dayz.js.org ) compared to my next one Hugo (no link again) but Hugo was the fastest to generate since its made in Go. Then I used different documentation generator like Docute ( https://datastructures.js.org https://datastructures.js.org ) & Docsify, etc... Then now. Personal opinion but I love Gatsby ( https://www.gatsbyjs.org https://www.gatsbyjs.org ). For me, it is the best static site generator out there. Yes more than static site generator as it is a PWA by default. It is infinitely scalable. It prefetches content before its loaded (think about this as you get the data of Previous Blog Post & Next Blog Post when you are on the Current Blog Post). Its so fast that you will actually feel the speed. Also, with little efforts you can make it work offline too.
