For me, the killer feature of Gitbook is something like « branched content? » (https://docs.gitbook.com/editing-content/editing-pages/chang...).

Retype without this type of feature is like many other documentation website generators.

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.
