No client-side JavaScript mode

Server-rendered online app

This online version is processed on the Ubuntu server using PHP, MySQL and Redis. Player signup, login, club creation, stadium upgrades, youth academy upgrades, test ad rewards, match simulation and admin login all use standard HTML forms.

• No game logic is run in browser JavaScript.
• No <script> tags are emitted by the PHP templates.
• The HTML response sends a Content Security Policy with script-src none.
• The Unity client and API still remain available for mobile, Windows, Mac and Linux later.

Python or Perl could also be used server-side, but the current stack already runs server-side through PHP 8.5 and avoids client-side processing.
