Send push notifications to your phone or desktop via PUT/POST
ntfy (pronounce: notify) is a simple HTTP-based pub-sub notification service. It allows you to send notifications to your phone or desktop via scripts from any computer, entirely without signup, cost or setup. It's also open source if you want to run your own.
Publishing messages 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, the topic is essentially a password, so pick something that's not easily guessable.
Here's an example showing how to publish a message using a POST request (via curl -d):
curl -d "Backup successful 😀" ntfy.sh/mytopic
-H "Title: Unauthorized access detected" \
-H "Priority: urgent" \
-H "Tags: warning,skull" \
-d "Remote access to $(hostname) detected. Act right away." \
Here's what that looks like in the Android app:
Subscribe to a topic
Subscribe from your phone

Subscribe to topics here and receive messages as desktop notification. Topics are not password-protected, so choose a name that's not easy to guess.
Subscribe using the API
Here's an example for JSON. The connection stays open, so you can retrieve messages as they come in:
$ curl -s ntfy.sh/mytopic/json

ntfy has so many more features and you can learn about all of them in the documentation (I tried my very best to make it the best docs ever 😉, not sure if I succeeded, hehe).
