About ntfy

ntfy is a notification service that uses HTTP publish-subscribe messaging. Scripts, REST API calls, or any tool that can make an HTTP request can send messages to a topic, and subscribed phones or desktops receive them as push notifications. The homepage says the service runs on Android, iOS, and the web, and that it has a Python client and a command-line example using curl.

Users can try the service for free without signing up. Without sign-up, a topic name works essentially as a password, so the homepage advises choosing a name that is hard to guess. Reserving topic names requires a paid plan. The homepage lists paid plans with daily message limits, reserved topic counts, phone call and email allowances, and attachment size limits that vary by plan. It also states that the software is free and open source and can be self-hosted.
