ntfy

ntfy (pronounced "notify") is a simple, HTTP-based pub-sub notification service. It lets you send push notifications to your phone or desktop from any computer or script with a simple HTTP request, entirely without sign-up.

This template runs a self-hosted ntfy server. Cache, attachments, and the user database are persisted to a local volume. By default the server is open (read-write); set AUTHDEFAULTACCESS to deny-all and create users with the ntfy CLI to lock it down.
