ntfy
ntfy is a push notification client that lets you receive alerts from scripts, apps, and self-hosted servers using simple HTTP topics.
What is ntfy?
ntfy is a utility app for receiving push notifications sent through the ntfy service and compatible self-hosted ntfy servers. It is designed for developers, admins, and power users who want a simple way to send alerts from scripts, automation tools, and web services to their devices. Users can subscribe to topics, receive messages as notifications, and follow events such as backup results, server logins, or completed jobs. The app supports self-hosted setups, authentication for supported servers, and newer versions add attachment and image support. On Apple platforms, the App Store listing shows availability for iPhone, iPad, and Apple silicon Macs, making it useful in mixed mobile and desktop workflows. ntfy is published by Philipp Heckel as part of the broader ntfy notification platform.

Safety overview
Status: Safe
ntfy is legitimate notification software. It normally needs notification permission so alerts can appear on your Mac, and it may handle message content that you or your services send to subscribed topics. If you use public or easy-to-guess topic names, other people could potentially publish or read those messages depending on how the topic is configured, so use private topic names or your own server for sensitive alerts.
Recommendation: Keep ntfy if you use it for server alerts, automation, or personal notification workflows. If you no longer rely on those notifications, you can remove it without affecting macOS itself, though you may stop receiving alerts from your scripts or self-hosted services.
