ntfy.sh is a super simple pub-sub notification service. It allows you to send desktop and (soon) phone notifications
|
|
via scripts, without signup or cost. It's entirely free and open source. You can find the source code <a href="https://github.com/binwiederhier/ntfy">on GitHub</a>.
|
|
</p>
|
|

|
You can subscribe to a topic either in this web UI, or in your own app by subscribing to an SSE/EventSource
|
|
or JSON feed. Once subscribed, you can publish messages via PUT or POST.
