Which service for sending push notifications is suitable in this situation?

Question

Android

I, as a person who loves to automate everything, once wanted to quickly receive information from my scripts. After thinking, I decided that the ideal option would be some kind of service (at least on the left host, at least for deployment on my own), which would allow sending notifications. That is, this is how I see this scheme
1. I install their application on my android (I don’t want to scribble my own)
2. In scripts, at the right time I make an HTTP (s) request with the necessary data to the service
3. I receive a push notification on phone with the same data

Notifications will come from the browser, so you don't need to install anything. Works perfectly, the delay in sending a notification is 2-5 seconds
