Are any of these options a git repo under the hood for the actual knowledge base?

It’s very valuable to be able to have the double workflow of a nice web interface alongside a plain text developer git workflow and leads to a very future proof knowledge base.

There are quite a few options for markdown + git knowledge bases, eg. Obsidian. You can easily find more alternatives discussed here on HN by starting a search on Obsidian.

If you’re looking for more of a CMS there’s quite a few options out there, most notably static site generators like docusaurus or vuepress. Plug: I’ve built a small tool to generate the markdown from notion, which allows me to use notion as my CMS editor while keeping the generated site fully under my control. https://github.com/meshcloud/notion-markdown-cms

Obsidian is great, but only free for personal uses.

You are looking for a tool like NetlifyCMS, which uses Git for its data store behind a nice web UI.
