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 or cost. It's also open source (as you can plainly see) if you want to run your own.

I run a free version of it at ntfy.sh, and there's an open source Android app too.
