Fun fact: These extensions are not exclusive to NostrNet.work; you can turn each one into a PWA app.

The most interesting part is that anyone can attach these  extensions to their websites with just a few lines of code.

Just copy paste few lines of code in your HTML and you get the nostr Note, Calendar or any extension. I will post more on that later nostr:note1chem36ylm6duwjp6uu3t8an6lcg533vtca0g4ur8rkttn5v8k0kss5rj56
