    <h1>Send push notifications to your phone or desktop via PUT/POST</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.
        It allows you to send notifications to your phone or desktop via scripts from any computer,
        entirely <b>without signup, cost or setup</b>. It's also <a href="https://github.com/binwiederhier/ntfy">open source</a> if you want to run your own.

    <h2 id="publish" class="anchor">Publishing messages</h2>
    <p>
        <a href="docs/publish/">Publishing messages</a> can be done via PUT or POST. 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 a POST request (via <tt>curl -d</tt>):
    </p>
    <code>
        curl -d "Backup successful 😀" <span class="ntfyUrl">ntfy.sh</span>/mytopic
    </code>
    <p class="smallMarginBottom">
        There are <a href="docs/publish/">more features</a> related to publishing messages: You can set a
        <a href="docs/publish/#message-priority">notification priority</a>, a <a href="docs/publish/#message-title">title</a>,
        and <a href="docs/publish/#tags-emojis">tag messages</a>.
        Here's an example using some of them together:
    </p>
    <code>
        curl \<br/>
        &nbsp;&nbsp;-H "Title: Unauthorized access detected" \<br/>
        &nbsp;&nbsp;-H "Priority: urgent" \<br/>
        &nbsp;&nbsp;-H "Tags: warning,skull" \<br/>
        &nbsp;&nbsp;-d "Remote access to $(hostname) detected. Act right away." \<br/>
        &nbsp;&nbsp;<span class="ntfyUrl">ntfy.sh</span>/mytopic
    </code>
    <p>
        Here's what that looks like in the <a href="docs/subscribe/phone/">Android app</a>:
    </p>

        <figcaption>Urgent notification with pop-over</figcaption>
    </figure>

    <h2 id="subscribe" class="anchor">Subscribe to a topic</h2>
    <p>
        You can create and subscribe to a topic either <a href="docs/subscribe/phone/">using your phone</a>,
        in <a href="docs/subscribe/web/">this web UI</a>, or in your own app by <a href="docs/subscribe/api/">subscribing via the API</a>.
    </p>

    <h3 id="subscribe-phone" class="anchor">Subscribe from your phone</h3>
    <p>
        Simply get the app and start <a href="docs/publish/">publishing messages</a>. To learn more about the app,
        <a href="docs/subscribe/phone/">check out the documentation</a>.

    </p>
    <p>
        Here's a video showing the app in action:

    </figure>

    <h3 id="subscribe-web" class="anchor">Subscribe via web app</h3>
    <p>
        Subscribe to topics in the <a href="app">web app</a> and receive messages as <b>desktop notification</b>.
        It is available at <b><a href="app"><span class="ntfyUrl">ntfy.sh</span>/app</a></b>.
    </p>
    <figure>
        <a href="app"><img src="static/img/screenshot-web-detail.png" width="100%"/></a>
        <figcaption>ntfy web app, available at <a href="app"><span class="ntfyUrl">ntfy.sh</span>/app</a></figcaption>
    </figure>

    <h3 id="subscribe-api" class="anchor">Subscribe using the API</h3>
    <p>
        There's a super simple API that you can use to integrate your own app. You can consume
        a <a href="docs/subscribe/api/#subscribe-as-json-stream">JSON stream</a>,
        an <a href="docs/subscribe/api/#subscribe-as-sse-stream">SSE/EventSource stream</a>,
        a <a href="docs/subscribe/api/#subscribe-as-raw-stream">plain text stream</a>,
        or <a href="docs/subscribe/api/#websockets">via WebSockets</a>.
    </p>
    <p class="smallMarginBottom">
        Here's an example for JSON. The <b>connection stays open</b>, so you can retrieve messages as they come in:
    </p>
    <code>
        $ curl -s <span class="ntfyUrl">ntfy.sh</span>/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"}<br/>
        ...
    </code>
    <p>
        Here's a short video demonstrating it in action:
    </p>
    <figure>
        <video controls muted autoplay loop src="static/img/android-video-subscribe-api.mp4" style="max-width: 650px"></video>
        <figcaption>Subscribing to the JSON stream with <tt>curl</tt></figcaption>
    </figure>

    <h3 id="docs" class="anchor">Check out the docs!</h3>
    <p>
        ntfy has so many more features and you can learn about all of them <a href="docs/">in the documentation</a>
        (I tried my very best to make it the best docs ever 😉, not sure if I succeeded, hehe).
    </p>

        <a href="docs/"><img width="100%" src="static/img/screenshot-docs.png"/></a>
        <figcaption>Check out the documentation</figcaption>
    </figure>

    <h3 id="free-software" class="anchor">100% open source &amp; forever free</h3>
    <p>
        I love free software, and I'm doing this because it's fun. I have no bad intentions, and I will
        never monetize or sell your information. This service will always stay
        <a href="https://github.com/binwiederhier/ntfy">free and open</a>.
        You can read more in the <a href="docs/faq/">FAQs</a> and in the <a href="docs/privacy/">privacy policy</a>.
