The short version

  • Each has a real cost: Flask requires manual configuration of many common features like authentication, ORM, and admin panels; WordPress self-hosted installation requires PHP 8.3 and MySQL 8.0 or MariaDB 10.11 minimum; older versions expose security vulnerabilities
  • They diverge on capability: Flask covers Lightweight framework, WordPress covers Content management.
