ntfy
A simple self-hosted push notification tool: subscribe to a topic and get pinged from anywhere.
ntfy sends push notifications over HTTP to a phone or desktop with almost no setup: pick a topic name, subscribe to it in the app, and anything published to that topic shows up as a notification within seconds.
It covers the same ground as Gotify with an even lighter footprint, and its dead-simple publish-by-URL design makes it easy to bolt notifications onto a script or automation without any real integration work.
