<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>
<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>
<div id="error"></div>
<form id="subscribeForm">
<input type="text" id="topicField" size="64" autofocus />
<input type="submit" id="subscribeButton" value="Subscribe topic" />
