I'm no Nostr Vet either, only for a year or so. My basic understanding is that its the underlying technology/protocol (much like what Haveno is to RetoSwap).
So anyone can use the open source code to integrate into a 'third party' service to access it, and also tweak it to how they want to use it.
Nosmore/Monstr are basically built on the Nostr network and customized the algorithm, UI and some config settings to allow for adding 'Monero Zaps' or tips with a connected Monero wallet. I have no had much luck with using these harnesses. So I stick to Nostr native clients to have a smoother experience reading and intersecting with posts and just manually searching for and following the Monero community.
