Getting started

ntfy lets you send push notifications to your phone or desktop via scripts from any computer, using simple HTTP PUT or POST requests. I use it to notify myself when scripts fail, or long-running commands complete.

Step 1: Get the app

To receive notifications on your phone, install the app, either via Google Play or F-Droid. Once installed, open it and subscribe to a topic of your choosing. Topics don't have to explicitly be created, so just pick a name and use it later when you publish a message. Note that topic names are public, so it's wise to choose something that cannot be guessed easily.

For this guide, we'll just use mytopic as our topic name:

Creating/adding your first topic

That's it. After you tap "Subscribe", the app is listening for new messages on that topic.

Step 2: Send a message

Now let's send a message to our topic. It's easy in every language, since we're just using HTTP PUT/POST, or with the ntfy CLI. The message is in the request body. Here's an example showing how to publish a simple message using a POST request:

curl -d "Backup successful 😀"
ntfy publish mytopic "Backup successful 😀"
POST /mytopic HTTP/1.1

Backup successful 😀
fetch('', {
    method: 'POST', // PUT works too
    body: 'Backup successful 😀'
http.Post("", "text/plain",
   strings.NewReader("Backup successful 😀"))"",
    data="Backup successful 😀".encode(encoding='utf-8'))
file_get_contents('', false, stream_context_create([
    'http' => [
        'method' => 'POST', // PUT also works
        'header' => 'Content-Type: text/plain',
        'content' => 'Backup successful 😀'

This will create a notification that looks like this:

Android notification

That's it. You're all set. Go play and read the rest of the docs. I highly recommend reading at least the page on publishing messages, as well as the detailed page on the Android/iOS app.
