Ntfy

Overview

ntfy (pronounce: notify) is a simple HTTP-based pub-sub notification service. It allows you to send notifications to your phone or desktop via scripts from any computer, entirely without signup, cost or setup. It's also open source if you want to run your own. Publishing a message to a topic is as simple as: curl -d "Backup successful 😀" ntfy.sh/mytopic By default, the ntfy server is open for everyone, meaning everyone can read and write to any topic (this is how ntfy.sh is configured). To restrict access to your own server, you can optionally configure authentication and authorization using NTFY_AUTH_FILE and NTFY_AUTH_DEFAULT_ACCESS. After that, simply create an admin user: ntfy user add --role=admin phil password: mypass confirm: mypass user phil added with role admin Once you've done that, you can publish and subscribe using Basic Auth with the given username/password.
