This looks like something I've been looking for! Excited to give it a try! I don't even use a password manager because of the things you've seemed to work around here. It's been painful.

Honestly, though, I'm most intrigued by your P2P solution. I've built a couple of web apps as custom html elements that use indexedDB for storage and I've been trying to figure out the sweet spot for syncing the data between apps. I think this nostr relay hits the mark as something people can feel comfortable not self hosting, while power users can host their own solution. Seems like a great solution, to me! Any advice as to some footguns with the approach? I'm very interested in giving it a try myself[0], so any notes you think would prevent some re-work would be really appreciated!
