PHP Server Monitor is a script that checks whether your websites and servers are up and running. It comes with a web based user interface where you can manage your services and websites, and you can manage users for each server with a mobile number and email address.

Notifications from any, third party, app

You can keep your phone in your pocket and still know what’s going on. Stay up-to-date on your incoming WhatsApp messages, know when someone's calling you, or read any of the other notifications from any app on your iPhone.

You can mute apps so you won't receive notifications from apps that are also running on your Mac.

Pushover makes it easy to get real-time notifications on your Android, iPhone, iPad, and Desktop (Android Wear and Apple Watch, too!)
