Safari Push Notifications is an Apple developer service that delivers notifications directly to your Mac. Beyond the web app notification use case, it is a useful tool for organisations to deliver notifications directly to their teams — without spending an additional $299 for an enterprise developer licence for in-house applications.

If you have backend web services, mission critial processes that can’t afford downtime, or real time market analysis being processed behind the scenes, Safari Push Notifications are very useful for keeping you in the loop without spamming email or developing custom apps just for status updates.
