This is how all of my nostr projects have started... I have a need. Everything else sucks or isn't what I want. So I build it myself.

If you build it for your needs then probably it’s not dogfood and others would use it as well unless it’s not public, I think it’s a good approach for great app ideas
gnostream and grain are very much open source and I'd like to think they're both really good. GitHub is linked in my bio.
