Shaark VS Gotify

There's something called Shaark which was inspired by Shaarli I think. It's creator is in the process of releasing a V2 (they resurfaced 3 weeks ago).

Shaark is a good option as well if you’re looking for similar tools. https://github.com/MarceauKa/shaark

shaark - Alternative to Wallabag, Shiori, Shaarli, etc. I didn't stick around with any of them, but that doesn't mean you will, too.

I found this self-hosted platform For keep and share contents which is awesome but nowhere I could find any installation tutorial for it except it's own docker installation documentation which with it I was able to successfully deploy it with portainer but I don't know how to config the stack network or nginx or bind9 in order to work with it (I'm very new to this :)

I use apprise with Gotify

You can self-host a notification service using https://gotify.net/ for example, but you may need to ask the user to disable battery usage restrictions if you don't want the OS to kill the background process.

If you do not need the state tracking, but instead need something that can deliver push notifications to you, check out ntfy and gotify

Gotify (version 2.5.1): A client for receiving push notifications

I've found Gotify to work well for that

Just FYI - there's also shoutrrr and gotify with similar functionality. I've tried them, they're very good, but not fitting my (very humble) needs.
