mdbook: https://rust-lang.github.io/mdBook/

> Publishing a book

> Once you've written your book, you may want to host it somewhere for others to view. The first step is to build the output of the book. This can be done with the mdbook build command in the same directory where the book.toml file is located:

> `mdbook build` This will generate a directory named book which contains the HTML content of your book. You can then place this directory on any web server to host it.

I'm not sure this meets the OP's requirements, but this is what I was going to recommend as well.

I've used mdBook exclusively since moving off GitBook in 2019 when they dropped their OS/local project and highly recommend it for how easy it is to setup and use.
