Researched this a while back but didn't find anything, so I'll ask here.

I'm looking for a flatfile CMS that would let me a) manage everything in a git repo and b) add logic to my site somehow.

Something like Netlify gets part of it right. You can manage content via git and include functions that are mounted at /.netlify/functions, but I can't host that myself and their prices are/were insane.

https://getgrav.org is closest to what I want and I'm using it now, but its git-sync plugin is a little vicious beast that will murder whatever repo you sync it with unless you set it up just so, and I'm not looking forward to trying to get that right again. No, I'm not being hyperbolic. https://github.com/trilbymedia/grav-plugin-git-sync/issues/213

If possible, I'd also like to tweak pages pre-render so I can, for instance, not show site sections/links if a user is authenticated or similar. I can do PHP if I must, but I'm way more familiar with just about every other ecosystem. #AskFedi
