<h1>ntfy.sh - simple HTTP-based pub-sub</h1>
|
|
<p>
|
|
<b>ntfy</b> (pronounce: <i>notify</i>) is a simple <b>HTTP-based pub-sub notification service and tool</b>.
|
|
It allows you to send <b>desktop notifications via scripts</b>, entirely <b>without signup or cost</b>.
|
|
It's entirely free and open source. You can find the source code <a href="https://github.com/binwiederhier/ntfy">on GitHub</a>.

<h2>Subscribe to a topic</h2>
|
|
<p>
|
|
Topics are created on the fly by subscribing to them. You can create and subscribe to a topic either in this web UI, or in
|
|
your own app by subscribing to an <a href="https://developer.mozilla.org/en-US/docs/Web/API/EventSource">EventSource</a>,
|
|
a JSON feed, or raw feed.
|
|
</p>
|
|
<p>
|
|
Because there is no sign-up, <b>the topic is essentially a password</b>, so pick something that's not easily guessable.
|
|
</p>
|
|
|
|
<h3>Subscribe via web</h3>
|
|
<p>
|
|
If you subscribe to a topic via this web UI in the field below, messages published to any subscribed topic
|
|
will show up as <b>desktop notification</b>.
|
|
</p>
|
|
<form id="subscribeForm">
|
|
<p>
|
|
<label for="topicField">Topic ID:</label>
|
|
<input type="text" id="topicField" size="64" placeholder="Letters, numbers, _ and -" pattern="[-_A-Za-z]{1,64}" autofocus />
|
|
<input type="submit" id="subscribeButton" value="Subscribe topic" />
|
|
</p>
|
|
</form>
|
|
<p id="topicsHeader">Subscribed topics:</p>
|
|
<ul id="topicsList"></ul>
|
|
|
|
<h3>Subscribe via your app, or via the CLI</h3>
|
|
<tt>
|
|
curl -s ntfy.sh/mytopic/raw # one message per line (\n are replaced with a space)<br/>
|
|
curl -s ntfy.sh/mytopic/json # one JSON message per line<br/>
|
|
curl -s ntfy.sh/mytopic/sse # server-sent events (SSE) stream
|
|
</tt>
|
|
|
|
<h3>Publishing messages</h3>
|
|
<p>
|
|
Publishing messages can be done via PUT or POST using. Here's an example using <tt>curl</tt>:
|
|
</p>
|
|
<tt>
|
|
curl -d "long process is done" ntfy.sh/mytopic
|
|
</tt>
|
|
<p>
|
|
Messages published to a non-existing topic or a topic without subscribers will not be delivered later.
|
|
There is (currently) no buffering of any kind. If you're not listening, the message won't be delivered.
|
