<h1>ntfy.sh</h1>
Topics:
<ul id="topics">
</ul>
<p>
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.
</p>
<input type="text" id="topic" size="64" autofocus />
<button id="topicButton">Add topic</button>
<button onclick="notifyMe('test'); return false">Notify me!</button>
<p>
<b>Usage:</b> 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.
</p>
