ntfy

Push notifications you can host yourself.

Publish alerts to an ntfy topic, either on ntfy.sh or on a server you run. For teams who would rather not route operational alerts through a third-party service, this keeps the delivery path on infrastructure you control.

Self-host it if you want. Point the connection at your own ntfy server and no third party sits in the alert path.
Or use ntfy.sh. The hosted instance works the same way if you would rather not run another service.
Open and simple. ntfy is open source and topic-based, which makes it easy to reason about and easy to subscribe to from anywhere.

01 · Why teams pick it

Control over the delivery path.

Most push services require trusting someone else with your operational alerts. ntfy is the option that does not.

Self-hosted delivery

Running your own ntfy server means alerts never traverse a third-party service you do not control.

No account required

Topic-based delivery means there is no per-user account management to maintain alongside your team list.

Easy to subscribe

Anyone who needs the alerts subscribes to the topic from their own device without you provisioning anything.

Fits self-hosted stacks

If you are already running your own infrastructure, ntfy tends to fit the way you work better than a commercial push service.

Pick your topic carefully

On a public instance, anyone who knows the topic name can subscribe to it. Choose something unguessable, or self-host.

Still needs data

Like any push notification, delivery depends on a data connection. Keep SMS or a phone call for the critical path.

Questions

Common questions

Can I use my own ntfy server?

Yes. The connection works with ntfy.sh or with a server you host yourself. Self-hosting means alerts are delivered entirely through infrastructure you control.

How do I connect ntfy to Hesklo?

Choose a topic name and decide whether you are using ntfy.sh or your own server, then add an ntfy connection in the monitor editor sidebar with those details. Subscribe to the topic on your devices and use Send test to confirm delivery.

Is a public ntfy topic secure?

On a public instance, anyone who knows the topic name can subscribe to it. Choose a topic name that is not guessable, or run your own ntfy server if the alerts are sensitive.

How does ntfy compare to Pushover?

Both deliver push notifications. Pushover is a commercial hosted service, while ntfy is open source and can be self-hosted. If keeping the delivery path under your own control matters, ntfy is the one that allows it.
