I've been really getting into the flat file CMS's recently. I just did a quick project using Grav and its use of twig and yaml made the set up a breeze. With NGINX and not having to muck around with a database I was able to stick the whole thing on a Raspberry Pi and physically handed them their server to plug into the router. I won't dread the next build if these lightwieght CMS's keep popping up.
Yeah, i'm the same with the non-SQL HTML generators like Hugo etc. I can't believe how many websites get owned through a blog when all they need is static HTML.
It's almost like people are getting used to the idea of reducing their attack service...
