retype

While gitbook does wrap the branching/merging process in a UI that is digestible by non-developers, Retype is far more powerful because you actually use GitHub (or GitLab). You have the full power of GitHub, including branching, pull-requests, issues, reviews, automation, authentication, and everything else. For example, here's the repo for the retype.com website, see https://github.com/retypeapp/retype The entire website is built from simple Markdown text files.

BookStack looks interesting, but certainly one massive advantage Retype has is just installation. I can have Retype installed, my website built, and running in a browser in a 10 seconds. With Retype, your content source are simple Markdown `.md` text files. BookStack stores your data in a database, and in order to host a website you need a PHP webserver, Maria DB, etc. A Retype generated website can be hosted for free using GitHub Pages. The retype.com website is hosted on GitHub Pages, see https://github.com/retypeapp/retype. Hope this helps.

Retype builds directly off Markdown files, which you can store anywhere, including GitHub. The retype.com website is built directly from a GitHub repo, see https://github.com/retypeapp/retype The retype.com website is also hosted on GitHub Pages. Any change that is committed to the GitHub repo will trigger the website to be rebuilt by Retype using GitHub Actions, see https://retype.com/hosting/github-pages/. Hope this helps clarify that Retype is even more tightly integrated with GitHub, or any other source management system. You have complete control and ownership of your source content files.

One will want to be aware of the licensing for this: https://github.com/retypeapp/retype/blob/v2.2.0/LICENSE.md "Free" as in beer, it seems
