Hi #Nostr!

I'm a developer working with Go and Swift, and today I'm excited to announce the launch of my first Nostr client — Nopu.

Nopu is a free and open-source push notification service built on Nostr. Think of it as ntfy.sh for Nostr — you can define custom filters to receive flexible, personalized push notifications from any event source on the nostr network.

In the future you can also self-host your own push service and config your client, giving you full control over how and where notifications are delivered.

The project is now open source:

* Backend (Go): https://github.com/sanah9/nopu

* iOS Client (Swift): https://github.com/sanah9/nopu-ios

TestFlight is also available for anyone who'd like to try it out:

Feedback and contributions are very welcome!
