What backend library dependencies do CI Wiz-generated apps have?

None at the PHP/backend level beyond the CodeIgniter 4 framework itself and its own Composer dependencies. CI Wiz generates its own base classes (GoBaseController, GoBaseModel, etc.) directly into your project — they are plain PHP files you own, not a library you pull in. On the frontend the generated views depend on Bootstrap 5, jQuery, DataTables, and Select2, all loaded from CDN links in the layout template. If you want to self-host those assets, you can replace the CDN references — nothing in the generated PHP assumes they come from any particular URL.
