Router and its fastroute adapter were tagged. This version adds support for multiple hosts via Route::hosts() and Group::hosts():

Route::get('/')
    ->hosts(
        'https://yiiframework.com/',
        'https://yiiframework.ru/'
    );
    
Group::create()
    ->hosts(
        'https://yiiframework.com/',
        'https://yiiframework.ru/'
    );
