+1, I use Grav too for my blog. Admin panel is really light, there's a lot of skeletons based on modern templates and they are a much smaller number which can be bad but also good so that you don't get overwhelmed by crappy stuff like it happens with Wordpress.
I first thought cool. On second look I see it is based on PHP. I'm sure newest PHP is really fast and advanced but I don't want to invest any of my time on that language (just my personal opinion).
Update: OK, it also runs on nginx. Made a wrong claim it does not run on it. Sorry.
Well that shouldn't be true. Firstly there is no good reason why any PHP framework would ever require a specific web server, so the claim seems dubious. A little reading in their installation guide confirms Grav should work with any web server: https://learn.getgrav.org/basics/installation
- No DB. Use a flat file layout similar to Jekyll or static site generators.
- Offers dynamic features like redirecting and custom routing when you need it. This isn't possible with a pure static site generator.
- Decent optional panel to write, edit and manage almost all aspects of your site.
- Quite fast once you set it up with good caching.
