Gatsby produces static html sites and then rehydrates them once loaded, which is what makes it feel so fast. Elm dynamically generates the html.

There has been some work to generate static html from Elm - https://github.com/eeue56/elm-static-html - and there's no technical reason I'm aware of that prevents it from being taken as far as Gatsby does.

I've been doing some work on an Elm-based static site generator: https://korban.net/elm/elmstatic/

(It uses elm-static-html under the hood.)
