ntfy sends push notifications to the ntfy app on your phone or desktop. Use the public server ntfy.sh or your own server.
Choose a topic
A topic is the name that your ntfy app subscribes to. Use letters, digits, "-" and "_", at most 64.
On ntfy.sh, anyone who knows a topic name can read its messages. Pick a name that is hard to guess, for example acme-uptime-3f9k2, or use a protected topic with an access token.
Add the channel
- In the ntfy app, subscribe to your topic.
- Open Alerting and click Add channel.
- Select ntfy.
- Enter a name and the topic.
- Optional: enter your own server URL. Leave it empty for ntfy.sh. Your server must be reachable from the internet.
- Optional: enter an access token for a protected topic or a server that denies anonymous access. We send it as a Bearer token and never show it again.
