# ntfy
|
|
|
|
ntfy (pronounce: *notify*) is a super simple pub-sub notification service. It allows you to send desktop and (soon) phone notifications
|
|
via scripts. I run a free version of it on *[ntfy.sh](https://ntfy.sh)*. **No signups or cost.**
|
|
|
|
## Usage
|
|
|
|
### Subscribe to a topic
|
|
Topics are created on the fly by subscribing to them. You can create and subscribe to a topic either in a web UI, or in
|
|
your own app by subscribing to an [SSE](https://en.wikipedia.org/wiki/Server-sent_events)/[EventSource](https://developer.mozilla.org/en-US/docs/Web/API/EventSource),
|
|
or a JSON or raw feed.
|
|
|
|
Because there is no sign-up, **the topic is essentially a password**, so pick something that's not easily guessable.
|
|
|
|
Here's how you can create a topic `mytopic`, subscribe to it topic and wait for events. This is using `curl`, but you
|
|
can use any library that can do HTTP GETs:
|
|
|
|
```
|
|
# Subscribe to "mytopic" and output one message per line (\n are replaced with a space)
|
|
curl -s ntfy.sh/mytopic/raw
|
|
|
|
# Subscribe to "mytopic" and output one JSON message per line
|
|
curl -s ntfy.sh/mytopic/json
|
|
|
|
# Subscribe to "mytopic" and output an SSE stream (supported via JS/EventSource)
|
|
curl -s ntfy.sh/mytopic/sse
|
|
```
|
|
|
|
You can easily script it to execute any command when a message arrives. This sends desktop notifications (just like
|
|
the web UI, but without it):
|
|
```
|
|
while read msg; do
|
|
notify-send "$msg"
|
|
done < <(stdbuf -i0 -o0 curl -s ntfy.sh/mytopic/raw)
|
|
```
|
|
|
|
### Publish messages
|
|
Publishing messages can be done via PUT or POST using. Here's an example using `curl`:
|
|
```
|
|
curl -d "long process is done" ntfy.sh/mytopic
|
|
```
|
|
|
|
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.
|

|
## FAQ
|
|
|
|
### Isn't this like ...?
|
|
Probably. I didn't do a whole lot of research before making this.
|
|
|
|
### Can I use this in my app?
|
|
Yes. As long as you don't abuse it, it'll be available and free of charge.
|
|
|
|
### What are the uptime guarantees?
|
|
Best effort.
|
|
|
|
### Why is the web UI so ugly?
|
|
I don't particularly like JS or dealing with CSS. I'll make it pretty after it's functional.
|
|
|
|
## Will you know what topics exist, can you spy on me?
|
|
If you don't trust me or your messages are sensitive, run your ntfy on your own server. That said, the logs do not
|
|
contain any topic names
