Using healthchecks.io and ntfy.sh to wake you up if your services are down

I use ntfy (on another instance) + healthchecks.io to wake me up at night when ntfy.sh is down (crazy inception, right?). It's the "poor man's PagerDuty" if you will. It works amazingly.

Here's how I set it up:

  • I signed up healthchecks.io (free plan) and configured a project for "ntfy.sh" with a "ntfy" integration, i.e. publish to ntfy.example.com/<secret> with max priority
  • I have two different hosts execute small "integration ntfy.sh tests" and only ping healthchecks.io if they succeed. If they don't healthchecks.io will publish to ntfy.example.com/<secret>
  • In the ntfy Android app, I subscribe to ntfy.example.com/<secret>, enable "Keep alerting on highest priority", and make it override DND (do not disturb) for this topic.

Now when ntfy.sh goes down, the integration tests in the cronjobs will fail, and so healthchecks.io will not be pinged, which will trigger it to publish to ntfy.example.com/<secret> and let my phone consistently ring until I acknowledge it.

I just have to say, I really love ntfy.

Years ago I used an app called simplepush, even bought the premium key. Installed it half a year ago and now they've changed to a yearly subscription. Fair enough. So I thought about throwing something together in python just to replicate the functionality just for my personal use... but luckily I searched and found ntfy first.

Really appreciate the work.

Thank you for the kind words. Feel free to recommend ntfy to your (nerd) friends if you like, haha.

Oh wow it's the man himself! Have to say you've put together an amazing piece of software! It has become an amazing tool in my alerting infrastructure. Thank you! for the wonderful project
