Both website are serving HTML: as long as you generate HTML you can serve easily either way.

LLVM is using Sphinx to turn its documentation from RST to HTML and copy this to the webserver.
MLIR is using Hugo <https://gohugo.io/> (see mlir-www <https://github.com/llvm/mlir-www/>) to turn its .md into HTML and serve it directly from GitHub pages.

There aren't any real underlying technology from the website point of view, MLIR could be hosted with LLVM as well, and use the same theme, etc.

The use of Markdown in MLIR is mostly historical I believe (Google uses heavily markdown for its doc and MLIR started at Google).

The use of GitHub pages instead of llvm.org is because the admins told me back in the fall when I was setting up the website that "it would be nice to migrate llvm.org to GitHub pages".
