The code is horrible:

Tight coupling of the HTML/PHP and JS.

If they were going to use PHP, at least they could have used Laravel or Symfony and had standardized libraries for authentication, views etc.

I just checked their Composer.json, looks like it uses CodeIgniter ... so maybe there is a framework in there but still the code quality is atrocious: https://github.com/ad-aures/castopod/blob/develop/composer.j...
