ntfy is a simple HTTP-based pub-sub notification service for sending push notifications to phones and desktops. It lets users publish messages to topics using basic HTTP requests, scripts, curl commands, or application integrations. The service can be used through the public ntfy.sh instance or self-hosted on private infrastructure. It is useful for server alerts, cron job results, monitoring notifications, CI/CD updates, and personal automation. ntfy includes web, mobile, and command-line clients, making it accessible across different environments. Its main value is providing lightweight, open-source notifications without forcing users into a heavy messaging platform or paid push service.
