How to make your own push notifications without third party api?

Question

Programming

Hey guys.
There are a lot of manuals, but I have not seen how to do it without a third-party api.
Maybe someone read it, or maybe even someone who did it himself. Is it possible to make your own push notification script?

Answer 1

Apple Push Notification service (APNs)
Firebase Cloud Messaging (formerly GCM)
are the 2 main push outlets for bucket, chrome and apple.
Well, or googling push notification server
If you mean your own server in general.

Answer 2

you can use HTML5 Notifications

I tested it in Chrome, FireFox, Opera - works great

Answer 3

With PushSharp, you can create your own API for sending notifications. In fact, this is a wrapper over the standard FCM, APNS.
