How to Setup Batflat on Ubuntu Linux with Nginx

Batflat is a light, fast, and bootstrap-ready flat-file CMS (Content Management System) that allows users and webmasters to create websites without the need for a separate database. Just download the web content files and enjoy!

It offers features that may not be available to other PHP-based CMS, like WordPress Joomla, or Drupal.

For one, it doesn’t need a database server, call it database-less. It is only 1024 kilobytes, and it has all features that you need but is smaller than WordPress, like SEO-friendly design, flexible CSS framework, and more.

Batflat uses a unique algorithm to find or list any content based on date, type, category, tag, or author, and the performance will remain fast even if you have thousands of posts and hundreds of tags.

Batflat began as a database-less flat file content management system. Its structure allowed you to have just the amount of functionality you needed in a flat file CMS solution, adding extensions (blade packs) for further functionality, whilst allowing setup on simple servers with no database.
