Ntfy is a platform for sending push notifications to your desktop or phone by simply using a PUT/POST HTTP request. In other words, it’s pub-sub. Clients publish to a topic and subscribers to the topic will be notified when something new is published. Simple and effective way to get your own push notifications. I’ve previously written how I use Ntfy with Tasker.

One of the limitations that I had to deal with when I switched to GrapheneOS originally was that there was no mechanism for push notifications without Google’s Firebase Cloud Messaging. I had a particular use case where I needed notifications and so I started using Gotify to get notifications from a stock Android phone (with Google) to my new phone running GrapheneOS. I’m now using ntfy, but the principle is the same.
