Show HN: Self-hostable app to send push notifications and files to phone/desktop

Hello friends, I posted here about ntfy before (https://github.com/binwiederhier/ntfy, see https://news.ycombinator.com/item?id=29715464 for previous discussion), but I've added a ton of features, so I thought I'd share some updates.

For those who don't know, 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 app and a web app.

You can use it like this (more in the docs):

   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.

Since my last post, I added the following features: Publish messages as JSON, custom user actions via action buttons, ntfy:// deep links, ntfy support in Apprise (thanks to @caronc), translations into 13 languages in the web app and Android app, lots of example usages, e.g. with NodeRED, Gatus, Sonarr, Radarr; a super cool chat-style message bar in the web app, and more.

I am happy to answer any and all questions, and I'd love some feedback or new ideas.
