Subscribe from the Web UI

You can use the Web UI to subscribe to topics as well. Simply type in the topic name and click the Subscribe button.

While subscribing, you have the option to enable background notifications on supported browsers.

• If background notifications are off:

  This requires an active ntfy tab to be open to receive notifications. These are typically instantaneous, and will appear as a system notification. If you don't see these, check that your browser is allowed to show notifications (for example in System Settings on macOS).

  If you don't want to enable background notifications, pinning the ntfy tab on your browser is a good solution to leave it running.

• If background notifications are on:

  This uses the Web Push API. You don't need an active ntfy tab open, but in some cases you may need to keep your browser open.

  Background notifications are only supported on the same server hosting the web app. You cannot use another server, but can instead subscribe on the other server itself.

  If the ntfy app is not opened for more than a week, background notifications will be paused. You can resume them by opening the app again, and will get a warning notification before they are paused.
