CMSimple_XH – a flat file CMS
CMSimple_XH is a fast, small, easy-to-use and easy-to-install modular Content Management System (CMS), which doesn't need a database.
It is free Open Source Software under the GPL3 Licence.
CMSimple_XH stores the content of the different pages in one single html-file (content.htm).
As of CMSimple_XH 1.7 the pages are separated by special HTML comments in content.htm, so H1-H6 can be used to structure each page.
