Bludit

I used it recently on two different websites and it was a breeze to install/use/customize. Perfect if you need a CMS with zero learning curve. You have users management available right out of the box and a modern/clean UI. I chose it primarily because the admin interface is also translated into Japanese and I didn't regret my choice for lots of other reasons. I recommend it warmly ... not to mention that the developper is very active on the support forum. That's a CMS you can't find easily which is the reason I decided to share its existence on Product Hunt. I tested it alongside with Grav and I found Bludit much more quick/easy to use/setup.
