… 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.
I like ntfy.sh a lot. Sending a notification is a simple cURL request, and they have mobile apps. Also I gotta mention healthchecks.io for any cron job or uptime monitoring, which has ntfy.sh support built in.
Exactly what I use. Both are very low footprint, so they sit on an old raspberry pi, with the rest of the services on the n100. Works great for me.
