17 Free Open-Source Flat-File CMS in PHP (Laravel, Symphony, and Pure PHP)

What is a Flat-file CMS?

Flat-file content management systems (CMSs) expertly address the issue of eliminating the need for a database to store content and configuration. Relying exclusively on flat-files instead of a database, they robustly safeguard against SQL-injection. Moreover, they optimally utilize server resources, far more efficiently than their traditional database-dependent CMS counterparts.

Indeed, backing up these apps is a breeze. You just have to duplicate the content and configuration files and tuck them away securely.

However, it's crucial to understand that the pristine condition of our servers isn't always guaranteed. Misconfigurations or improper setups could introduce security vulnerabilities.

These potential risks can impact our apps, opening the door to hacking, data loss, and leaks. But with vigilance and correct practices, these risks can be managed effectively.
