Show HN: Ntfy.sh – open-source push notifications via PUT/POST

Hello folks, I posted here about ntfy before, but since my last post it's been a loooong time, so I thought I'd give an update to this fantastic community.

ntfy is a a tool that lets you send push notifications to your phone from any script or server using a simple HTTP PUT/POST requests. It's 100% open source and self-hostable, and has an Android/iOS app and a web app.

You can use ntfy like this (more in the docs: https://ntfy.sh/docs/publish/). This will send a notification to your phone:

   curl -d "Backup on $(hostname) complete" ntfy.sh/mytopic

I host free and open version on ntfy.sh, but you can host your own of course.
