Eleventy is a site generator that is flexible and production-ready. Eleventy is known for its best-in-class build-performance for JavaScript tools, zero-client-JavaScript footprint, and its friendly community of folks that like to build speedy web sites.
It's modern. It's fast. It has good tooling support. There are lots of templates. There are integrations with popular tech such as tailwind and webpack. If you are not allergic to NPM, then give this a shot.
Eleventy is the SSG I reach for first. I actively run both my personal and business websites on 11ty. The product's focus on HTML and CSS is refreshing in a sea of JS generators.
