WonderCMS

Smallest flat-file CMS — one file, no database

About WonderCMS

WonderCMS is an extremely small flat-file content management system for building simple websites and blogs. A site runs from a handful of files with content stored in a JSON file, so there is no database server and no configuration: you log in, click the text, and edit in place. Themes and plugins install in one click, making it ideal for small personal and business sites.
