GetSimple is a clean and simple Content Management System, and its 2.01 release was released recently.
Their motto, “GetSimple has everything your client needs, and nothing a CMS doesn’t”, is remarkable. Because there aren’t that many developers that put that much thought into usability.
The CMS basically features everything a CMS needs. The data is stored in XML files, so no MySQL is involved.
GetSimple has an “Undo” function, which allows undoing almost every action.
It is easy to theme, easy to use, and great for small websites. Your clients will love it.
