I saw the installation page, but I still am not sure whether I can install it on a hosting such as platform.sh or pantheon. Actually I am looking for a free open source push notification system which I can install on a php, mysql, apache hosting.
If I try to explain the type of hosting I am talking about, I would give you an example of Drupal or Wordpress CMS. Both can be installed easily. This is what I am looking for. An easy to install notification system. I will be using it with drupal 7.
There are tutorials available to integrate 3rd party api using REST in drupal. So once I installed a push notification server or some kind of message send/receive system like gotify, It should not be a problem integrating it with drupal 7 using REST api.
Hope you understood what I am trying to ask
