… specifically, the thing to deliver alerts from your servers to your phone or whatever. I’m using Discord, because it doesn’t depend on my own infrastructure, and I can make a private “alerts” channel on my private server. But I’d like to switch to something that’s not Discord. I’m using alertmanager, FWIW.


ntfy, self-hosted offsite on an old phone, it takes around 300mA, ie.less than a watt.
ntfy app on my phone.
Wireguard between them.
Have they fixed support for mTLS?
+1 for ntfy it’s great. I’m using their free servers though and it just routes my curl’d alerts to the phone app. Will have to look into self hosting it that sounds neat, love that you repurposed an old phone for that.
Adminforge also runs a free public ntfy server: https://ntfy.adminforge.de/
It’s not super difficult. They provide setup instructions and then you just connect to your new instance instead of the public one.
