<h1>ntfy.sh - simple HTTP-based pub-sub</h1>
<p>
<b>ntfy</b> (pronounce: <i>notify</i>) is a simple HTTP-based <a href="https://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern">pub-sub</a> notification service.
2021-10-24 20:22:53 +02:00
It allows you to send <b>desktop notifications via scripts from any computer</b>, entirely <b>without signup or cost</b>.
2021-10-24 05:30:10 +02:00
It's also <a href="https://github.com/binwiederhier/ntfy">open source</a> if you want to run your own.

<h2>Publishing messages</h2>
<p>
2021-10-29 19:58:14 +02:00
Publishing messages can be done via PUT or POST using. Topics are created on the fly by subscribing or publishing to them.
Because there is no sign-up, <b>the topic is essentially a password</b>, so pick something that's not easily guessable.
</p>
<p class="smallMarginBottom">
Here's an example showing how to publish a message using <tt>curl</tt>:
</p>
<code>
curl -d "long process is done" ntfy.sh/mytopic
</code>
<p class="smallMarginBottom">
Here's an example in JS with <tt>fetch()</tt> (see <a href="https://github.com/binwiederhier/ntfy/tree/main/examples">full example</a>):
2021-10-24 04:49:50 +02:00
</p>
2021-10-29 19:58:14 +02:00
<code>
fetch('https://ntfy.sh/mytopic', {<br/>
&nbsp;&nbsp;method: 'POST', // PUT works too<br/>
&nbsp;&nbsp;body: 'Hello from the other side.'<br/>
})
</code>
<h2>Subscribe to a topic</h2>
2021-10-24 04:49:50 +02:00
<p>
2021-10-29 19:58:14 +02:00
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>
2021-10-23 03:26:01 +02:00
2021-10-24 04:49:50 +02:00
<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
2021-10-24 05:30:10 +02:00
will show up as <b>desktop notification</b>.
2021-10-24 04:49:50 +02:00
</p>
<form id="subscribeForm">
<p>
<label for="topicField">Subscribe to topic:</label>
2021-10-25 14:54:46 +02:00
<input type="text" id="topicField" placeholder="Letters, numbers, _ and -" pattern="[-_A-Za-z]{1,64}" />
2021-10-24 20:22:53 +02:00

<h3>Subscribe via your app, or via the CLI</h3>
<p class="smallMarginBottom">
2021-10-29 19:58:14 +02:00
Using <a href="https://developer.mozilla.org/en-US/docs/Web/API/EventSource">EventSource</a> in JS, you can consume
notifications like this (see <a href="https://github.com/binwiederhier/ntfy/tree/main/examples">full example</a>):
</p>
<code>
2021-10-25 14:54:46 +02:00
const eventSource = new EventSource('https://ntfy.sh/mytopic/sse');<br/>
eventSource.onmessage = (e) => {<br/>
&nbsp;&nbsp;// Do something with e.data<br/>
};
2021-10-24 20:22:53 +02:00
</code>
<p class="smallMarginBottom">
2021-10-29 19:58:14 +02:00
You can also use the same <tt>/sse</tt> endpoint via <tt>curl</tt> or any other HTTP library:
</p>
<code>
$ curl -s ntfy.sh/mytopic/sse<br/>
event: open<br/>
2021-10-29 19:58:14 +02:00
data: {"id":"weSj9RtNkj","time":1635528898,"event":"open","topic":"mytopic"}<br/><br/>
2021-10-29 19:58:14 +02:00
data: {"id":"p0M5y6gcCY","time":1635528909,"event":"message","topic":"mytopic","message":"Hi!"}<br/><br/>
event: keepalive<br/>
2021-10-29 19:58:14 +02:00
data: {"id":"VNxNIg5fpt","time":1635528928,"event":"keepalive","topic":"test"}
</code>
<p class="smallMarginBottom">
To consume JSON instead, use the <tt>/json</tt> endpoint, which prints one message per line:
</p>
<code>
$ curl -s ntfy.sh/mytopic/json<br/>
{"id":"SLiKI64DOt","time":1635528757,"event":"open","topic":"mytopic"}<br/>
{"id":"hwQ2YpKdmg","time":1635528741,"event":"message","topic":"mytopic","message":"Hi!"}<br/>
{"id":"DGUDShMCsc","time":1635528787,"event":"keepalive","topic":"mytopic"}
</code>
<p class="smallMarginBottom">
2021-10-29 19:58:14 +02:00
Or use the <tt>/raw</tt> endpoint if you need something super simple (empty lines are keepalive messages):
</p>
<code>
$ curl -s ntfy.sh/mytopic/raw<br/>
<br/>
This is a notification
</code>
2021-10-24 04:49:50 +02:00
2021-10-29 19:58:14 +02:00
<h3>Message buffering and polling</h3>
<p class="smallMarginBottom">
2021-10-29 19:58:14 +02:00
Messages are buffered in memory for a few hours to account for network interruptions of subscribers.
You can read back what you missed by using the <tt>since=...</tt> query parameter. It takes either a
duration (e.g. <tt>10m</tt> or <tt>30s</tt>) or a Unix timestamp (e.g. <tt>1635528757</tt>):
2021-10-24 04:49:50 +02:00
</p>
2021-10-24 20:22:53 +02:00
<code>
2021-10-29 19:58:14 +02:00
$ curl -s "ntfy.sh/mytopic/json?since=10m"<br/>
# Same output as above, but includes messages from up to 10 minutes ago
2021-10-24 20:22:53 +02:00
</code>
<p class="smallMarginBottom">
2021-10-29 19:58:14 +02:00
You can also just poll for messages if you don't like the long-standing connection using the <tt>poll=1</tt>
query parameter. The connection will end after all available messages have been read. This parameter has to be
combined with <tt>since=</tt>.
</p>
<code>
2021-10-29 19:58:14 +02:00
$ curl -s "ntfy.sh/mytopic/json?poll=1&since=10m"<br/>
# Returns messages from up to 10 minutes ago and ends the connection
</code>
<h2>FAQ</h2>
<p>
<b>Isn't this like ...?</b><br/>
Who knows. I didn't do a lot of research before making this. It was fun making it.
</p>
<p>
<b>Can I use this in my app? Will it stay free?</b><br/>
Yes. As long as you don't abuse it, it'll be available and free of charge. I do not plan on monetizing
the service.
</p>
<p>
<b>What are the uptime guarantees?</b><br/>
Best effort.
</p>
<p>
<b>Will you know what topics exist, can you spy on me?</b><br/>
If you don't trust me or your messages are sensitive, run your own server. It's <a href="https://github.com/binwiederhier/ntfy">open source</a>.
That said, the logs do not contain any topic names or other details about you. Check the code if you don't believe me.
